Dimensions.

"Long. 18, diam. 8 ’’’ [H 39.2, D 17.4 mm]"; figured specimen herein H 34.8, D 18.5, W 6.0.

Type material.

NHMUK 1975512, lectotype; 1975513, two paralectotypes (Cuming coll.).

Remarks.

The original measurements are interpreted as German lines (2.18 mm), and do not correspond to those of the specimen in the NHMUK. However, Pfeiffer’s collection is known to have been destroyed ( Dance 1966), and type material of this taxon is neither in the SMF ( Neubert and Janssen 2004) nor ZMB ( Köhler 2007) collections. The current systematic position follows Thompson (2011).

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) dunkeri dunkeri (Pfeiffer, 1846).
