Helix cactorum d'Orbigny, 1835 Figs 6D , L10iv

Helix cactorum d’Orbigny 1835: 10.

Bulimus hennahi Gray; d’Orbigny 1837 [1834-1847]: 283, pl. 30 figs 3-4 [3 April 1837; text 6 May 1838].

Type locality.

"provincia Tacnacensi (rep. Peruviana)".

Label.

"Tacna, Pérou”, in d’Orbigny’s handwriting.

Dimensions.

"Longit. 25 millim., latit. 15 millim."; figured specimen herein H 24.4, D 12.8, W 7.0.

Type material.

NHMUK 1854.12.4.189, lectotype and six paralectotypes ( d’Orbigny coll.).

Remarks.

Seven specimens are present in the d’Orbigny collection, of which one corresponds to d’Orbigny 1837 [1834-1847]: pl. 30 fig. 4; it is here designated lectotype (design. n.). This taxon has been synonymized with Bostryx hennahi (J.E. Gray, 1830) by Richardson (1995: 27); the latter species was described from ”Arica”, which is presumably meant to be in (nowadays) Chile, while Tacna is in southern Peru; both localities are in the coastal area.

Current systematic position.

Bulimulidae , Bostryx hennahi (J.E. Gray, 1830).
