NHMUK 1947.2.10.1, syntype (ex Rolle).

Rolle did not state on how many specimens his description was based upon. However, the shell height is close to the original measurements and together with the indication ”type” on the label in Rolle’s handwriting, there is no doubt about the status of the specimen. The locality is ambiguous, as there are several places called ”Huancabamba” in Peru. There were, however, several other species described from the same locality, amoung them Columbinia huancabambensis, which is regarded by Loosjes and Loosjes-van Bemmel (1984: 33), as occurring in northern Peru. Another species described in the same paper, Systrophia moellendorffii, was said by Haas (1955: 367) to have been rediscovered in the Chanchamayo valley [Dept. Pasco]. Given the fact that a third species described by Rolle—Newboldius illustris—is known to occur in the same region, makes it likely that Huancabamba in Dept. Pasco is the locality where Rolle’s taxon occurs. This species was hitherto considered as published in 1905 (Richardson 1995: 95); however, on the copy in the Smithsonian Institution Libraries the title page of the issue in which Rolle’s paper appeared is marked ”Rec’d Mar. 2/04” (see http://www.biodiversitylibrary.org/item/53294#page/211/mode/1up); p. 48 of this issue mentions ”Ausgegeben 22. Februar”.

Bulimulidae, Drymaeus (Drymaeus) abruptus (Rolle, 1904).

”Province of Quito, Ecuador”.

”Ecuador”, taxon label in Pfeiffer’s handwriting. M.C. label style IV.

NHMUK 1975497, lectotype; 1975498 five paralectotypes (Cuming coll.).

Pfeiffer did not state on how many specimens his description was based; no variety has been mentioned by him. Two sets of labels are with this lot, which is originating from the Cuming collection; one reading ”Ecuador” in the handwriting of one of Cuming’s secretaries. On both labels the taxon name is in Pfeiffer’s handwriting. One of the lots has been labelled ”abscissus var.” in a later handwriting.

Bulimulidae, Drymaeus (Drymaeus) abcissus (Pfeiffer, 1855).

”Longit. 52 mil., latit. 25 millim.”; figured specimen herein H 43.7 D 23.3, W 6.2.

NHMUK 1854.12.4.125, five paralectotypes (d’Orbigny coll.).

d’Orbigny did not state on how many specimens his description was based. The types series appears to have been split between the MNHN and NHMUK collections. None of the specimens in London match the original figures, while one of the specimens in Paris is close to the published dimensions. The current systematic position follows the synonymisation of this taxon with Helix hygrohylea d’Orbigny, 1835, by Miquel (1989b: 77); this author, however, overlooked that Helix abyssorum has page priority. Cuezzo et al. (2013) disageed with this synonymisation.

Bulimulidae, Drymaeus (Drymaeus) abyssorum (d’Orbigny, 1835).

”Long. 10, diam. 6 mill.”; figured specimen herein H 13.2, D 7.7, W 5.3.

NHMUK 20100651, two possible syntypes (Cuming coll.).

The specimens found are slightly larger than the original measurements; the largest has shell height 13.2 mm. The material—not accompanied by a taxon label in Pfeiffer’s handwriting—is from the Cuming collection, on which Pfeiffer based the description for this taxon; he did not state on how many specimens his description was based. The specimens are treated as possible syntypes.

”Long. 19, diam. 10 mill.”; holotype H 19, D 9.52, W 8.7.

NHMUK 1855.4.5.25, holotype (Cuming coll.).

Forbes writes ”This shell (...)”, therefore the single specimen found, together with the indication on the label that it was figured, makes it justifiable to consider it a holotype.

Bulimulidae, Naesiotus achatellinus (Forbes, 1850).

”Matto Grosso, Brazil”.

”Long. 33, diam. 14 mm.”; holotype H 33.4, D 14.1, W 7.4.

NHMUK 1907.11.21.10, holotype (da Costa coll.).

da Costa wrote ”A rather peculiar shell, unlike any known to the writer, who obtained it at the dispersal of the collection of the late Mr. Miers”; given the singular form, it may be assumed that da Costa only had one specimen at hand.

Bulimulidae, Drymaeus (Drymaeus) acuminatus da Costa, 1906.

NHMUK 1975377, lectotype; 1975378, two paralectotypes (Cuming coll.).

Pfeiffer did no indicate on how many specimens his description was based. He described two varieties from ”Chimborazo (Bourcier)”. The second label in the lot indicates ”var.” and ”Chimborazo, Equador / Mons. Bourcier / Consul General”. The systematic position at the species level follows Richardson (1995: 345).

Bulimulidae, Kuschelenia (Vermiculatus) aequatorius (Pfeiffer, 1853) (comb. n.).

”Meobamba, Peru (Mr. Gueinzius)”.

”Ecuador”; taxon label in Pfeiffer’s handwriting. M.C. label style I.

”Long. 17, diam. 7 1/3 mill.”; syntype H 16.9 D 7.9, W 6.4.

NHMUK 1975462, syntype (Cuming coll.).

Pfeiffer described this taxon from Cuming’s collection, but did not state on how many specimens his description was based. The specimen found corresponds to the shell height given by Pfeiffer. This is a case where the locality information provided by Cuming to the describer (viz. Pfeiffer) has been lost; the label ”Ecuador” on the frontside of the wooden tablet has been added in a later handwriting and may be erroneous.

Bulimulidae, Drymaeus (Mesembrinus) aesitvus (Pfeiffer, 1857) (comb.n.).

”in Peruviâ (Mexillones, desert of Atacama)”.

”Peru”; taxon name in Pfeiffer’s handwriting. M.C. label style I.

”long 1, lat. 1/2 poll. [H 25.3, D 12.7 mm]”; figured specimen herein H 27.5, D 12.6, W 8.3.

NHMUK 20100610, five possible syntypes (Cuming coll.).

Broderip described this taxon from the Cuming collection, but did not indicate on how many specimens his description was based. These specimens are herein regarded as possible syntypes; one is corresponding to Reeve’s figure. The presence of a label in Pfeiffer’s handwriting together with specimens apparently seen by Reeve as evidenced by the figured specimen, corroborates the assumption (Breure and Ablett 2011: 5) that—at least in some cases—material from the Cuming collection was either returned after having been sent to Pfeiffer or Pfeiffer made the identification during a visit to London.

Bulimulidae, Bostryx affinis (Broderip in Broderip and Sowerby I 1832).

NHMUK 1907.11.21.16, holotype (da Costa coll.).

da Costa did not clearly state on how many specimens his description was based. However, since he mentioned ”a shell” it may be safely assumed that he had only one specimen at hand.

Bulimulidae, Drymaeus (Drymaeus) alabastrinus da Costa, 1906.

NHMUK 1937.6.18.13-16, three possible paratypes, California Academy of Sciences Expedition 1905–1906 leg. (ex Schlesch).

The type status of these specimens is not fully resolved and is here viewed with much caution, as it remains unclear how Schlesch obtained specimens from the original series.

Bulimulidae, Naesiotus albemarlensis (Dall, 1917).

NHMUK 20100611, five possible syntypes (Cuming coll.).

Broderip described this taxon from the Cuming collection, but did not indicate on how many specimens his description was based. These specimens are herein regarded as possible syntypes; one is corresponding to Reeve’s figure. This is another case of material that has been studied by both Reeve and Pfeiffer. See also affinis Broderip, 1832.

Bulimulidae, Bostryx albicans (Broderip in Broderip and Sowerby I 1832).

According to the label, a paratype has been ”smashed [in] 1896”. The current systematic position follows Richardson (1995: 96).

”long. 0.8, lat. 0.5 poll. [H 20.3, D 12.7 mm]”; figured specimen herein H 15.0, D 10.7, W 4.7.

NHMUK 1842.5.10.149–151, three possible syntypes (Cuming coll.).

The name was introduced in Sowerby I 1833 [Sowerby I and II 1832–1841] as ”B. albus Brod.”. However, as can be seen in Sowerby I (1833 in Sowerby I and II 1832–1841: 73), the authorship should be credited to G.B. Sowerby I (”G.B.S.”). It is not known if this species was described from the Cuming collection, but this cannot be excluded a priori (see also Breure and Ablett 2011: 3). One specimen is closely resembling Sowerby’s figure. The material is herein considered as possible syntypes. The registration numbers suggest that six specimens were originally present; only three of these could be found.

As mentioned before, the publication dates of Sowerby’s publications are according to Coan et al. (2013a) and Duncan (1937). Interestingly, d’Orbigny 1838 [1834–1847]: 280 mentioned this taxon as ”Bulimus albus Broderip”, with reference to Sowerby I (1833 in Sowerby I and II 1832–1841), and said it had publication date 11 June 1833 [contra Duncan 1937: 78, who reports 20 September 1833]. At the same time he noticed that Duclos had published Bulimus olorinus on 15 June 1833 (Duclos 1833: pl. 24). The text pertaining to this plate describes this taxon from ”Chili”, based on a specimen from Duclos’ collection and collected by Gay. He signed the text with ”15 juin 1833”; however, it seems likely from the context that this was the date Duclos finished his description and not the date the text appeared in print. Without additional bibliographical research it seems premature to give priority to Duclos’ taxon. The current systematic position follows Richardson (1995: 15).

Bulimulidae, Bostryx albus (Sowerby I, 1833).

NHMUK 1975441/1–3, lectotype and two paralectotypes, Bourcier leg. (Cuming coll.).

Although the label given is more precise than the locality given in Reeve’s publication and the specimens bear a label in Pfeiffer’s handwriting, one of the shells does corresponds to the specimen figured by Reeve. The current systematic position follows Richardson (1995: 97).

Drymaeus (Drymaeus) ambustus (Reeve, 1849).

”Columbian Andes”.

NHMUK 1893.2.4.171, lectotype (Morelet coll.).

The type locality was broadly defined by Morelet and probably also covers adjacent parts of Dept. Apurimac. There are two places called ”Pomacocha” in the valley of Río Apurimac, one in Dept. Ayacucho and the other in Dept. Apurimac. Given the range in dimensions given by Morelet, it is clear that he had a larger type series at hand. The top of the lectotype is slightly damaged. There are additional lots in the MHNG collection, as described by Breure 1978. The current systematic position corresponds to Richardson (1995: 16).

Bulimulidae, Bostryx andoicus (Morelet, 1863).

NHMUK 1975450, lectotype, Schlim leg. (Cuming coll.).

This taxon is now considered a junior subjective synonym of Bulimus baranguillanus Pfeiffer, 1853 (syn. n.). The current systematic position is based on a revision of Colombian Drymaeus species (Breure and Borrero, unpublished data).

NHMUK 1975317, lectotype (Cuming coll.).

This is the first time a locality for this taxon is published; Bulimus apertus is now considered a junior subjective synonym of Bulimus orbignyi Pfeiffer, 1846 (syn. n.), whose type locality is ”Bolivia” (see under Bulimus orbignyi Pfeiffer). Any specific Peruvian locality for this taxon may likely be expected in one of the southern departments, close to the Bolivian border.

Preston did not state on how many specimens his description was based; the reference of Breure (1979) ”HT 1915.1.6.23” has to be interpreted as lectotype designation under Art. 74.6 ICZN. This is the first time the type has been figured.

NHMUK 1982297, holotype (see remarks).

Gray (1834) refers to the type material as ”This shell...”, which may imply that he had only one specimen at hand. It is a juvenile shell, with the lip damaged. The taxon was considered to be a junior subjective synonym of Helix elongata Röding, 1789 by Pilsbry (1899: 25), with which we concur.

NHMUK 1854.12.4.178–182, five lots with resp. eight, seven, seven, three and three syntypes (d’Orbigny coll.).

d’Orbigny (1935) did not state on how many specimens his description was based. In d’Orbigny (1838 [1834–1847]: 280) the localities were specified as ”sur les coteaux du Parna, province d’Entre-rios, près de Feliciano (...) près de San-Lorenzo, province de Santa-Fe. (...) la république de Bolivia (...) des provinces de Valle grande et de la Laguna (...); (...) des plaines de Santa-Cruz de la Sierra, (...) la province de Chiquitos”; see also Breure 1973. The shell of the largest specimen among the lots, in. 178, is broken on the ventral side. The protoconch of the type material proves to be smooth and the taxon is now being transferred from the genus Bulimulus Leach, 1814 to Bostryx Troschel, 1847 sensu Breure 1979 (but see Breure 2012b).

NHMUK 1975436, three possible syntypes (Cuming coll.).

Dohrn (1863) gives the measurements of five specimens, but it is unclear how many specimens his description was actually based upon. The specimens in NHMUK are accompanied by two sets of labels. One is in Dohrn’s handwriting (teste S.P. Dance, 1958) and has ”Huallaga” as the locality. The other label set originates from Farris and has ”Province of Patas, Andes of Peru”; the taxon name is in Pfeiffer’s handwriting, who identified it as Bulimus tessellatus Shuttleworth, 1852. The latter label may have been added to the material in a later stage. Due to the fact the other label has original handwriting, the specimens are considered possible syntypes. The current systematic position follows Richardson (1995: 239).

Bulimulidae, Neopetraeus atahualpa (Dohrn, 1863).

NHMUK 1866.1.3.8, two syntypes (ex Guppy).

Guppy described this taxon from immature specimens: ”The specimens from which the species was described by me in the Annals and Magazine of Natural History (1866) were young and imperfect.” (Guppy 1871: 307). There is another shell (NHMUK 1875.2.8.1), also presented by Guppy, which could be from the series he is referring to in the second paper; it is therefore not considered a syntype since this specimen was later collected than the type series, but unfortunately all three specimens have been mixed and there is no way of separating the two lots.

Bulimulidae, Drymaeus (Mesembrinus) aureolus (Guppy, 1866).

[Mexico] ”Cordova”.

”Cordova (Mexico)”; taxon name in Pfeiffer’s handwriting. M.C. label style I.

”Long. 22, diam. 10 mill.”; figured specimen herein H 21.8, D 11.1, W 5.1.

NHMUK 1975502, lectotype; 1975502/2, one paralectotype (Cuming coll.).

One of the two specimens found corresponds to the figure of Pfeiffer and is here selected as the lectotype (design. n.). The current systematic position follows Thompson (2011: 112).

Bulimulidae, Drymaeus (Mesembrinus) aurifluus (Pfeiffer, 1857).

”Venezuela”.

”Venezuela”; taxon name in Pfeiffer’s handwriting. M.C. label style I.

”Long. 39, diam. 14 1/2 mill.”; figured specimen herein H 38.8, D 20.1, W 6+.

NHMUK 1975499, lectotype (Cuming coll.).

Pfeiffer did not state on how many specimens his description was based. Only one specimen was found, which corresponds to Pfeiffer’s original measurements; the top is damaged.

Bulimulidae, Drymaeus (Drymaeus) auris (Pfeiffer, 1866).

”in provincia Peruviae Xagua” (see remarks).

”Prov. of Xagua, Peru”. M.C. label style I.

”long. 1, lat. 0.6 poll. [H 25.3, D 15.2 mm]”; figured specimen herein H 25.8, D 15.5, W 5.9.

NHMUK 20100631, three possible syntypes (Cuming coll.).

The specimen figured by Reeve was found in the collection and, together with two other specimens, are considered possible syntypes. The type locality may refer to Dept. Jauja in Central Peru (teste Crawford 1939: 330) or to Dept. Amazonas, Prov. Bagua; the latter seems slightly outside the range known for this subgenus. The current systematic position at species level follows Richardson (1995: 348).

Bulimulidae, Kuschelenia (Vermiculatus) bicolor (Sowerby I, 1835) (comb. n.).

[Peru] ”Balsa de Cocharcas”.

”Balsa de Cocharcas”, in Morelet’s handwriting.

”Long. 19, diam. 8 1/2 mill.”; figured specimen herein H 17.9, D 9.0, W 6.4.

NHMUK 1893.2.4.173, lectotype; 1893.2.4.174, paralectotype (Morelet coll.).

The current systematic position follows Richardson (1995: 35).

Bulimulidae, Bostryx nigropileatus (Reeve, 1849).

”Baranguilla in Andibus Colombianus”.

”Baranguilla / Andes of Colombia”; taxon label in Pfeiffer’s handwriting. M.C. label style IV.

”Long. 32, diam. 13 1/2 mill.”; figured specimen herein H 31.5, D 15.6, W 7.2.

NHMUK 1975452, lectotype (Cuming coll., ex Bland).

Bulimulidae, Drymaeus (Drymaeus) baranguillanus (Pfeiffer, 1853).

[West Indies] ”Barbados. (Mus. Cuming)”.

No locality given. The taxon label is in Pfeiffer’s handwriting. M.C. label style I.

”Long. 20, diam. 10 mill.”; figured specimen herein H 21.3, D 10.8 W 5.9.

NHMUK 1974054, lectotype; 1974055, two paralectotypes (Cuming coll.).

The current systematic position follows the revison of Breure (1974).

Bulimulidae, Bulimulus fuscus (Guilding, 1828).

[Peru, Dept. Cajamarca] ”Rio Yonan, Peru, 4000 feet (C.T. Baron)”.

”Rio Yonan, Peru, 4000’ / C.T. Baron”, in Fulton’s handwriting.

”Height 12 millim., maj. diam. 30 millim.”; figured specimen herein H 12.7, D 29.3, W 4.6.

NHMUK 1896.6.23.1, lectotype; 1896.6.23.2, one paralectotype, Baron leg. (ex Fulton).

Fulton did not mention on how many specimens his description was based. From Neubert and Janssen (2004: 201) it may be concluded that the type series was distributed to various museums. ”Rio Yonan” is the local name of Rio Jequetepeque at the village of Yonan, near Tembladera (V. Mogollón, pers. commun.).

Bulimulidae, Scutalus baroni (Fulton, 1896).
