Dimensions.

"Long. 37 mill., diam. 11 1/2"; figured specimen herein H 36.5, D 13.05, W 6.5.

Type material.

NHMUK 1975132, lectotype; 1975133, two paralectotypes, Buckley leg. (Cuming coll.).

Remarks.

Smith did not mention that he based himself on a shell from the Cuming collection; the question mark in his published type locality may be associated with this source (see Breure and Ablett 2011: 5). Also the number of specimens on which the description was based was not mentioned by Smith; therefore, the reference of Breure (1979) to "HT 1975132" has to be interpreted as a lectotype designation under Art. 74.6 ICZN. The current systematic position follows Richardson (1995).

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) orthostoma (E.A. Smith, 1877).
