Fig. 74

Helix cactorum d’Orbigny, 1835: 10 . – Breure & Ablett, 2014: 36 , figs 6D, L10i (lectotype designation).

Bulimus hennahi Gray. – d’Orbigny, 1837 [1834-1847]: 283, pl. 30 figs 3-4.

Type locality: “ provincia Tacnacensi (rep. Peruviana )”.

Label: “ Pérou ”, in Moricand’s handwriting.

Dimensions: “Longit. 25 millim., latit. 15 millim.”; figured specimen herein H 28.8, D 15.8, W 7.0.

Type material: MHNG-INVE-20659, four paralectotypes (ex d’Orbigny, Moricand coll.).

Remarks: These specimens originated from d’Orbigny are considered as type material; the author did not state on how many specimens his description was based. Seven specimens are present in the d’Orbigny collection in NHMUK, of which one was designated lectotype by Breure & Ablett (2014). This taxon has been synonymized with Bostryx hennahi (J.E. Gray, 1830) by Richardson (1995: 27) following d’Orbigny (1837 [1834-1847]); however, doubt remains as Breure & Ablett (2014) explained. Only further morphological and molecular research may solve this issue.

Current systematic position: Bulimulidae , Bostryx hennahi (J.E. Gray, 1828) ?
