Type material.

NHMUK 1905.11.17.2, lectotype (ex Fulton).

Remarks.

Fulton did not state on how many specimens his description was based. The specimen found corresponds to Fulton’s figure. Richardson (1995: 170) placed this taxon wrongly in the synonymy of Bulimus regularis Pfeiffer, 1852, which is a Brazilian taxon based on material collected by Macgillivray. Pfeiffer’s figure (Pfeiffer 1854 in Küster and Pfeiffer 1840-1865: pl. 39 fig. 22), copied by Simone (2006: fig. 366) and listed as Bulimulus regularis , is clearly different from Fulton’s taxon and may prove to be a non-orthalicoid.

Current systematic position.

Bulimulidae , Drymaeus regularis Fulton, 1905.
