Abstract

The type status is described of 39 taxa classified within the family Amphibulimidae (superfamily Orthalicoidea) and kept in the London museum. One taxon, Bulimus elaeodes Pfeiffer, 1853, is removed to the Strophocheilidae. Lectotypes are designated for Bulimus adoptus Reeve, 1849; Bulimus (Eurytus) eros Angas, 1878; Helix onca d’Orbigny, 1835; Amphibulima pardalina Guppy, 1868. The type status of the following taxon is changed to lectotype in accordance with Art. 74.6 ICZN: Strophocheilus (Dryptus) jubeus Fulton, 1908.

As general introduction to this and following papers on Orthalicoid types in the Natural History Museum, a brief history of the London collection is given and several examples of handwriting from different authors are presented.

Introduction

Annotated catalogues of type specimens are an important source of information on the primary types that constitute the basis of a stable taxonomy for a group. For the superfamily Orthalicoidea, with more than 1750 available taxa names, this has partly been achieved by the papers of Zilch (1971, 1972), Breure (1975, 1976, 2011), Neubert and Janssen (2004) and Köhler (2007). Breure (1979) and Breure and Schouten (1985) listed all the primary type material for this group, known at that time. During the course of an ongoing revision of the Orthalicoidea, which now also includes phylogenetic research (Breure et al. 2010, Breure and Romero in press), it became evident that a re-study of types and a documentation up to present-day standards were needed to ensure a stable taxonomy at the species level. This paper is a first contribution presenting the type material of the Orthalicoidea in the collection of the Natural History Museum (hereafter NHM or the Museum), London, United Kingdom, which now houses more than 600 types of nominal taxa from this group. For practical reasons, this paper is dealing with the Amphibulimidae only. However, in the following introduction to the collection and the handwritings found therein, some examples from other families within the Orthalicoidea will be mentioned; these other families will be treated in subsequent papers.

The collection

The NHM collection is famous for its large amount of primary types of taxa, many of which were described throughout the 19th Century. For a concise general history of the collections, see Stearn (1981: 194–197); for acquisitions up to 1904, see E.A. Smith (1906). Biographical references have largely been obtained from Coan et al. (2011). In the context of this paper, the following acquisitions are important to mention as they contained type material of several taxa dealt with herein.

In 1837 the Trustees of the Museum purchased the collection of William J. Broderip, which probably also contained type material of species he described together with Sowerby (Broderip and Sowerby 1832a, b). However, some of these types came into the Cuming collection (see below), and were further exchanged (see Köhler 2007, Neubert and Janssen 2004). Around the same time, part of the extensive collection made by Lansdown Guilding in the West Indies was acquired at an auction, containing “the actual types or co-types of the various species described by Mr. Guilding” (E.A. Smith 1906: 704). However, none of the taxa described by Guilding pertaining to the Orthalicoidea could be traced during this research.

The collection of Hugh Cuming has been a source for thousands of species descriptions, giving it a unique position in its time-frame. As far as can be traced from the registration books in NHM, several series were purchased during Cuming’s lifetime. In 1842 and 1843 the Museum purchased about 1800 specimens collected by Cuming, who lived for several years in Chile and made collecting trips to, among others, parts of South and Central America (Melvill 1895). He not only collected himself, but also gathered specimens from various sources, through exchange, and with the help of various assistants, e.g., Thomas Bland (see Martin 1886), Bourcier (possibly Jules Bourcier, who was at the time French consul to Ecuador; see Beolens and Watkins 2003), his son-in-law Thomas Bridges (Dall 1866), David Dyson (an assistant to Cuming, who collected in the Neotropics; le Tomlin 1945), Nicolas Funck (who was a draftsman to J. Linden and accompanied him during his collecting travels; his third trip was to Venezuela in 1841–1842 and he returned to that country in 1845; see Urban 1902), Gueinzius (possibly Wilhelm Gueinzius, who never travelled in South America, but who exchanged extensively with Eduard Friedrich Poeppig, a German naturalist who spent several years in Brazil, Chile, and Peru; see Urban 1902), Karl Theodor Hartweg (a German botanist who collected extensively in Central America, Ecuador and Colombia (see Urban 1902, Anonymous 2011a), William Lobb (an English plant collector who travelled in South America in 1840–1848; see Shepard 2003), John Miers (an English botanist who lived for some years in Brazil; see Anonymous 2011b), Auguste Sallé (a French malacologist; see Crosse 1897), Louis Joseph Schlim (travelled with J. Linden to Venezuela, New Granada, Jamaica and Cuba from 1841–1844, and together with N. Funck in 1845 to Guadeloupe and Venezuela; see Urban 1902), and Richard Spruce (an English botanist who spent approximately 15 years exploring the Amazon from the Andes to its mouth; see Seaward and Fitzgerald 1996). As far as we could detect none of the lots inspected were found accompanied with a label bearing Cuming’s handwriting (see also below). Cuming, “in the most free and liberal manner, opened the collection to the use of (..) conchologists and iconographers as would fall into his views as to the describing and naming of species” (Gray 1868: 726; cf. Gray 1869 where this account on the Cuming collection was re-published, spreading this tale also to the New World). Lovell Reeve and the Sowerby family made extensive use of this opportunity to describe and publish many species and publish series of books, as documented by Petit (2007, 2009). But Cuming also made contacts with continental malacologists, of which Louis Pfeiffer needs a special mention in the context of this paper. According to Neubert and Janssen (2004: 196) “in 1845, a large suite of terrestrial molluscs were exchanged with H. Cuming containing a considerable number of voucher specimens to the important works of (..) L. Pfeiffer”. Gray (1868: 728) says that “Mr. Cuming was in the habit of sending to Dr. Pfeiffer, Reeve, Sowerby, and other describers and figurers of the species certain specimens from his duplicates marked with the same number as that attached to his own specimens; and the determination of the species depended on the accuracy with which these numbers were reported” (see also below and Fig. 5). Although a few cases have been spotted during our revisionary work where an obvious mistake has been made, it has also been possible to match many specimens to the original dimensions or figures given by Pfeiffer, Reeve, and Sowerby. This implies that specimens on which species descriptions were based were often returned by Pfeiffer to Cuming’s collection. After the death of Cuming in 1865, the collection was acquired by the Museum in 1866 (E.A. Smith 1906: 710).

In 1844, the Museum obtained the material collected during the surveying voyage of H.M.S. Fly along the coasts of New Guinea and Australia (see Jukes 1847 [2011]). The material, collected by the naturalist John MacGillivray, contained several new species of Placostylidae later described by Pfeiffer. Also the material from the surveying voyages of H.M.S. Herald and H.M.S. Pandora, commanded by Captain Henry Kellett and Lieut. Wood respectively, along the coast of California and the Pacific coast of Central and South America (see Seemann 1853, Samson 1998, Colledge and Warlow 2010) was presented to the Museum shortly afterwards . Several species of Bulimulidae were described on the basis of this material by Edward Forbes (1850).

The collection of Alcide d’Orbigny came to London in 1854 (E.A. Smith 1906: 707). Part of it is based on the specimens collected during his journeys to South America (Gray 1854) and includes most of the specimens dealt with in his “Voyage...” (d’Orbigny 1834–1847) (dates according to Sherborn and Griffin 1934). Many taxa had been briefly described before in d’Orbigny (1835), but the importance of the “Voyage...” was mainly in the elaboration of the localities (see Breure 1973 for localisation in modern geography), and in accurately figuring most of the taxa. Between 1870 and 1886, the collection of Australian material made by George French Angas, containing many types, was donated by him to the Museum (see also Iredale 1959). In the same period the collection of Robert John Lechmere Guppy, an Englishman who lived for many years in Trinidad (see Newton 1917), came to the Museum. The material comprised the type specimens of taxa described by him from various islands in the West Indies. In 1875, the collection of Thomas Lombe Taylor was presented by his widow. Its importance is mainly marked by the many species described by Lovell Reeve in the “Conchologia Iconica” (see also Dance 1986: 170–171). In 1883 the Museum purchased the collection of Jean Baptiste Gassies (see Crosse and Fischer 1884), containing many types of Placostylidae described from New Caledonia. Ten years later the collection of Arthur Morelet came to London after having been bought at an auction by Fulton, a well-known dealer at that time (see Fulton 1920). It contained all the types described by Morelet, including several Bulimulidae from South America.

In 1901 Frederick DuCane Godman presented to the Museum his extensive collection of biological material from Central America. Jointly with Osbert Salvin he was co-editor of a multi-volume encyclopaedia on the natural history of that area, of which the land and freshwater Mollusca were treated by Eduard von Martens (1890–1901). The types of species described by von Martens can be found in the Godman collection. During the years 1902–1904, several type specimens described by James Cox (Placostylidae) and by James Cosmo Melvill and John H. Ponsonby (Prestonella) were either purchased or presented. Also type material described by S.I. da Costa and W.K. Weyrauch was presented by these authors to the Museum. Via dealers like H.B. Preston and Sowerby and Fulton, the Museum acquired material that had been either described by these dealers or originated from continental collections (e.g. Grateloup, Rolle).

For a complete understanding of the collection it is also necessary to know the history of its staff. While John Edward Gray was one of the first Keepers of the Zoology Collection (1840–1875), Edgar Albert Smith was certainly the most prominent staff member during the late 19th century; he joined the Museum in 1867 and retired in 1913. After his retirement, the Mollusca Section was formally set up. Guy Coburn Robson (1888–1945) was the first head of section, and had been working on the collections since 1911, when he entered the Museum after study at Oxford and in Naples. He had a particular interest in cephalopods, and published an important monograph in 1931–1936, but also wrote on broader problems of species and variation. When Robson resigned due to ill health in 1935 he was succeeded by George Ivor Crawford, who had studied at Cambridge and worked at the Marine Biological Laboratory in Plymouth. Crawford was followed in 1946 by William James Rees (1913–1967), who was heavily involved in the post-war reconstruction of the galleries and a reorganisation of the collections. Like Robson, he paid particular attention to the cephalopods until he moved to the Coelenterate Section in 1955. The fourth head of the Section was Ian Courtney Julian Galbraith, who was followed by Norman Tebble in 1959 when he transferred to the Bird Section. The heads of section were assisted by J. C. Vickery, who joined as a Boy Attendant in 1897, and finally retired as a Higher Grade Technical Assistant in 1947 (Hindle 1946, Crawford 1967, Stearn 1981).

Labels, author’s handwriting and matching specimens

Historical collections are not only a rich source of type material but they also permit us to have a glimpse back in time. Labels and their handwriting are often the sole remnants of work done by malacologists in the past. In the context of this project we came across many labels bearing original handwriting. Although some examples are given elsewhere (e.g. Dance 1966, Zilch 1967, Wood and Gallichan 2008, Breure 2011), it seems useful to present an overview of handwritings we encountered during this research and which we can attribute to authors of taxa (Figs 13, 4A–B).

As pointed out above, the Cuming collection is a rich source of material and this also extends to interesting labels. For example there are many examples (Fig. 4B) of labels with Pfeiffer’s handwriting, which is quite characteristic and has been published before (Zilch 1967: 36). Although it is difficult to reconstruct the past with an accuracy that rules out any assumptions, the following observations may help to partially explain the way the Cuming collection was dealt with. Cuming himself has rarely left his handwriting on labels (see also Petit 2007: 74). Most of his labels were written by his collectors and his assistants (e.g., Fig. 4G), who wrote an abbreviation for the genus name plus the locality data and a number that apparently was used to check when the determinations came back. On the last line of some labels we have found some unknown reference, e.g. “1 in No.”. Contrary to remarks found on labels added in a 20th Century handwriting, we are not of the opinion that this referred to the number of specimens, but instead to the number of lots that were sent under a given reference number (examples in Fig. 5). The examples also show that Cumingian material was either sent to Pfeiffer for identification and was afterwards returned to London, or Pfeiffer made his identifications during “his frequent trips to London to consult the Cuming collection” (Dance 1986: 122; see also Wheeler 1949: 52).

There has been some debate in literature about the accuracy of locality labels of Cuming material (Smith 1906: 710–711; Dance 1966: 167–170; Dance 1986: 127–129; Petit 2007: 30). “In many of the specimens, especially those that have not yet been determined or named, the habitat, written on a small paper label, is stuffed into the mouth of the shell” (Gray 1868: 727). Later these labels were gummed to the back of wooden tablets, as Gray (o.c.: 729) writes “I have had the shells of the Cumingian collection placed on [wooden] tablets so that they may be arranged in the same series as the other shells in the British Museum; but each tablet is marked in such a manner that it may be at once distinguished from the rest of the collection, so that there can be no doubt about which are the types or the presumed types of the species described from the collection”. These marks are “M.C.” or “Mus. Cuming” (Figs 6B–C). On the front side, the tablets have been covered with a sheet of gray paper, on which a summary of taxon name and locality data have been added, presumably after the arrival of the collection at the Museum. Around the turn of the century, glass-topped cardboard boxes came into use to house some of the specimens. In the course of the 20th Century, it was decided to start with removing the shells and the labels from these wooden tablets or to cut the bottom of the cardboard boxes, mainly to save space (K.M. Way, pers. commun.). Due to the enormous amount of material, this has only partly been achieved so far. Therefore shells from the Cuming collection can now be found with one of the following ‘label types’: (I) the labels are still gummed on one or both sides of wooden tablets (Fig. 6A); (II) the labels are gummed to the bottom of the cardboard box in which the specimens are housed, with a summarizing label on the top side behind the glass lid (Fig. 6D); or (III) only the bottom of the cardboard has been preserved to which the labels are still glued (Figs 6B–C); (IV) the labels have been soaked off and are kept in archival pockets placed together with the specimens in an open box (Fig. 6E).

The specimens figured by Reeve in his ‘Conchologia Iconica’ (see also Petit 2009: 46) are never accompanied by written labels from that author (Figs 4C–E); instead, they have small printed labels with the taxon name on one side and the reference to a plate and figure on the other side (‘label type’ V: Fig. 4F); the font and position suggests that these labels were cut from a spare index to the ‘Conchologica Iconica’. The shells in these lots can generally be matched to the published figures, as these are very accurate with regard to the shell shape, size and colour (K.M. Way, pers. comm.). However, several instances have been found where lots labelled in the indicated way could not be matched to the original figures; it may have been that also duplicate sets have been labelled with these printed labels. The shells are usually figured in the “Conchologia Iconica” to their actual size, or the figures are accompanied by lines that indicate such size although two additional observations are worthwhile mentioning. While Reeve is known to have generally indicated by a scale bar whenever he figured a shell larger than actual size, some exceptions have been encountered (e.g., Plate XIV). The second observation is related to the way the shells might have been measured. Whenever the shells were elongate in shape with a high height/diameter ratio, the figured specimen always gave a good match. However, when the shell was more globose (viz. a lower height/diameter ratio), the figured specimen only had a good match when it was placed with the aperture downside; thus contrary to more modern practices where shells are always measured perpendicular to the ventral view.

In the collection, labels were found with handwriting that is attributed to the following persons (references to biographical data included): Henry Adams (Crosse and Fischer 1878; Fig. 1A), César-Marie-Félix Ancey (Wood and Gallichan 2008; Fig. 2D), George French Angas (Melvill 1890; Fig. 1G), William John Broderip (Melvill 1890; Fig. 3A), Matthew William Kemble Connolly (le Tomlin 1947; Fig. 3H), George Ivor Crawford (Fig. 1D), Joseph Charles Hippolyte Crosse (Poyard 1898; Fig. 3E), Solomon Israel da Costa (Melvill 1908; Fig. 1E), Wilhelm Dunker (Kobelt 1885; Fig. 3B), Hugh Coomber Fulton (Smith 1906; Fig. 1F), Edward Forbes (Melvill 1890; Fig. 2G), Jean Pierre Sylvestre de Grateloup (Fischer 1862; Fig. 4A), John Edward Gray (Anonymous 1875; Fig. 2C), Robert John Lechmere Guppy (Newton 1917; Fig. 3C), Karl Eduard von Martens (Kobelt 1905; Fig. 1H), James Cosmo Melvill II (Jackson 1930; Fig. 2H), Arthur Morelet (Crosse 1893; Fig 2E), Alcide d’Orbigny (Germain 1933; Fig. 3D), Louis Pfeiffer (Crosse and Fischer 1878; Figs 4B, 5), Rudolp Amandus Philippi (Barros 1904; Fig. 4G), Hugh Berthon Preston (Winckworth 1946; Fig. 2A), Paul Hermann Reibisch (Schniebs 1999; Fig. 2F), Hermann Rolle (Zilch 1967; Fig. 1B), Ralph Tate (Blake 1902; Fig. 2I).

When interpreting possible type material, it is always good practice to check against the original publication (e.g. locality, dimensions, collector). However, when working with historical collections, one cannot always expect the same data that is given in present-day publications, and often one has to investigate with a biohistorical time-frame in mind. In the case of material dating back to the early 19th century, written accounts documenting the history of a collection have vanished in many cases or label handwriting has faded away. And while malacologists like Broderip, Reeve, and Sowerby generally have not left their handwriting in collections (but see Fig. 3A for an exception), it may safely be assumed that they were in contact and may well have swapped material amongst their collections (K.M. Way, pers. comm.). In general, lots originating from older collections, such as the Cuming collection, may not always be accompanied by label data that exactly matches the locality data given in the original publication. Some cases were found where labels have been added during later years, giving a different or broader defined locality than the original label has (Fig. 4D; compare the original published description and the label found in the Cuming collection, with a handwriting that is probably of an assistant during the late 19th century). This may have added in some instances to confusion in subsequent literature about the occurrence and distribution of a taxon.

The locality label is probably in the handwriting of Robert Furley Geale, who worked for Cuming as an Assistant for many years (P. Dance, pers. comm.). The characteristic abbreviation “M.C.”, added after the collection had arrived in the NHM in 1866, appears in black ink in the left-hand corner. B–C Only the bottom of the cardboard has been preserved to which the labels are still glued. The summarizing label (with text written on lines) is kept as the second label.

Methods

When assessing possible type material, the following criteria have been applied: (a) the authorship and the locality fit with the original description (but see note above on the differences which may occur between published locality data and those on labels); (b) alleged type material is in accordance with the established understanding of the taxon. In order to fulfill the requirements of article 74 of the International Code of Zoological Nomenclature (ICZN), any lectotype designations herein are to be understood as to have the sole purpose to fix the status of these specimens as the sole name-bearing type of that nominal taxon, to ensure the name’s proper and consistent application, even when this is not explicitly done in every single case but abbreviated as “lectotype designation”. Lectotypes designated herein are made using the following criteria, in order of preference: (1) the relevant specimen was figured in the original description, or in subsequent revisionary works; (2) if no original figure was published, a specimen was selected that matches as closely as possible the measurements given in the original description. If it is known that the original collection has been destroyed (e.g., Pfeiffer, Strebel; teste Dance 1966), and specimens have been found with labels in the original author’s handwriting or originating from the original author, these are herein treated as possible syntypes.

For each taxon the original publication—in which the taxon was proposed—is mentioned, as well as papers in which reference is made to the

Type material. The type locality is quoted from the original publication in the original wording and language, with clarifying notes between square brackets. The name of the collector, if given in the original paper, is only mentioned (in italics) if it might give a clue about the type status of material present in the collection. The text of the original, or oldest, label is quoted, together with information from subsequent labels if containing information necessary for a correct interpretation. All labels have been photographed and are figured for future historic reference. The original dimensions are quoted, if necessary transferred to mm (see Stöver 1986; see also Rowlett 2004). Dimensions of the type specimens have been taken with a digital caliper, using the methods figured by Breure (1974: fig. 2); measurements up to 10 mm have an accuracy of 0.1 mm, those above 10 mm are accurate to 0.5 mm. Due to improvements in accuracy of calipers, the measurements given herein are in several cases slightly different from those reported by Breure (1978), Breure and Eskens (1981) and Breure and Schouten (1985). Comparing the current measurements to those quoted from the original publication, one should be aware that the diameter especially may have been measured differently. In the case of syntypes, only the largest specimen has been measured. Under type material the NHM-registration numbers are given; if specimens from different localities are present, the order of the lots corresponds with the information of the different labels. The number of specimens originally available, if quoted by the original author, are mentioned under
Remarks.
Remarks are further given to describe any individual characteristics of the type specimens or any other details of the type lot. The current systematic position is given, following the generic scheme of Breure (1979) and the familiar arrangement of Breure et al. (2010) and Breure and Romero (in press).

Abbreviations used for depositories of material are: NHM, Natural History Museum, London, U.K.; RMNH, Netherlands Centre for Biodiversity Naturalis, Leiden, the Netherlands; SMF, Natur-Museum Senckenberg, Frankfurt am Main, Germany; ZMB, Zoologisches Museum, Humboldt Universität, Berlin, Germany.

Systematics Systematic list of taxa arranged in generic order

This systematic list follows the generic classification from Breure (1979), amended as proposed by Breure and Romero (in press), and unpublished data from the senior author; genera are presented in alphabetical order. As for some genera no phylogenetic data have been obtained yet (e.g. Dryptus), their familiar relationship remains tentative until a more satisfactory arrangement can be presented.

NHM 1905.5.3.1, lectotype, ex Fulton.

Remarks.

Fulton (1908) remarked that he had seen four specimens. This specimen is the only one which is marked “type”; the top is damaged and thus the original shell height must have been larger than quoted above. The holotype designation by Breure (1979) has to be interpreted as lectotype designation (Art. 74.6 ICZN). During their recent revision, Borrero and Breure (2011) compared the type material to that of Dryptus guerini (Pfeiffer, 1846), but tentatively retained Fulton’s taxon as a separate species.

The material is accompanied by a label signed by E.A. Smith, indicating that the specimen was figured in Pfeiffer (1854–1860) and were considered “types” by him. Since Pfeiffer based himself on Cuming’s material for this taxon, the type status is here not questioned despite the fact that a label in Pfeiffer’s handwriting is missing.

NHM 1975474, lectotype, ex Dunker (Cuming coll.).

Remarks.

The type locality as given in Philippi (1842–1844) is in error, as this species is only known from Venezuela. Apparently Dunker had seen three specimens, as he writes “I owe the figured specimen to the kindness of Consul Mr. Gruner from Bremen, in whose collection there are two additional, identical specimens”. According to Dance (1966) the Dunker collection is in Berlin, with many types in the Cuming collection. The whereabouts of the Gruner collection are unknown to us. Köhler (2007) does not list any type material of this taxon, hence the Cuming collection seem to be the only extant source of material originating from Dunker. The type status of the London specimen is not questioned as it is accompanied by a label in Dunker’s handwriting. The specimen, which was chosen lectotype by Breure (1978), is considerably smaller than the original dimensions and does not fit the figure in Philippi (1842–1844).

The locality on the label corresponds to the type locality of Helix pentadina d’Orbigny, 1835, which has been synonymized with Helix onca by subsequent authors; the former name has page precedence. The specimen corresponding to d’Orbigny 1837 [1834–1847]: pl. 30 fig. 1 is now selected lectotype (design. n.). According to Gray (1854) the type specimen of Bulimus pentadinus d’Obigny is missing.

Remarks.

The material is accompanied by several later labels with the indication “type” or “holotype”. The specimen is damaged at the peristome. The shell is sculptured with spiral series of granules, a characteristic which accords better with Plekocheilus (Eurytus). Close examination of the yellowish colour marks reveal that these are unlike the ‘air pockets’ commonly found in Plekocheilus (Aeropictus).

Remarks.

This taxon was placed in the synonymy of Plekocheilus (Eurytus) plectostylus (Pfeiffer, 1848) by Borrero and Breure (2011). During the prolonged time this paper was in press, the material of both taxa could be studied in the NHM. Both the size of the shell and the sculpture is markedly different (cf. Figs 20D and 25D). The previous subgeneric classification of Plekocheilus speciosus is thus retained.
