Type material.

Remarks.

In his original publication Pfeiffer stated the type locality as unknown. In Pfeiffer (1848b: 208) he quoted "prope Lima (De Lattre)". This may have led Pilsbry (1896 [1895-1896]: 162) to put this taxon into the synonymy of Bulinus modestus Broderip, 1832. However, as the material has the taxon label in Pfeiffer’s handwriting, and the measurements closely agree with those originally given, the type status is here not disputed. It is assumed therefore that this is a Bolivian taxon. Breure (1979) classified this taxon with Bulimulus Leach, 1814. The protoconch sculpture consists of rather straight axial riblets, which is atypical for this genus. Pfeiffer’s taxon is now transferred to Naesiotus sensu Breure 1979 (comb. n.).

Current systematic position.

Bulimulidae , Naesiotus orbignyi (Pfeiffer, 1846).
