Type locality.

"in Peruviâ. (Ancon)".

Label.

”Peru”. M.C. label style I.

Dimensions.

"long. 5/10 lat. 3/10 poll. [H 12.6, D 7.6 mm]"; figured specimen herein H 11.6, D 7.7, W 5.5.

Type material.

NHMUK 20100635, five probable syntypes; 20100636, five probable syntypes (Cuming coll.).

Remarks.

There are two lots with the same same label. As Broderip described this taxon from Cuming’s collection, we consider them as probable syntypes; see also the remarks under Bulinus scabiosus . One of the specimens of lot 20100635 corresponds to Reeve 1848 [1848-1850]: pl. 21 fig. 129a; the other figure (129b) corresponds to one of the specimens from the second lot (20100636). The current systematic position follows Richardson (1995).

Current systematic position.

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