Label.

Type material.

NHMUK 1975265, lectotype; 1975117, one paralectotype, Dyson leg. (Cuming coll.).

Remarks.

Pfeiffer (1846a: 30) mentioned that his material originated from Dyson, which is confirmed by the information on the label. Therefore there is no doubt about the type status of the specimens. However, Pfeiffer’s dimensions (H/D ration 1.85) do not fit the specimens found in the NHMUK collection (H/D ratio 2.08). The figure as presented by Reeve 1849 [1848-1850] confirms the latter ratio, which makes it likely that Pfeiffer’s measurements are either erroneous or that he had more material in his own collection. As the Pfeiffer collection must considered to be lost ( Dance 1966), the London specimens are the sole reference. We consider it probable that the published dimensions of Pfeiffer are in error.

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) hondurasanus (Pfeiffer, 1846).
