Label.

”Tobago”, in H. Adam’s handwriting.

Dimensions.

"Long. 24, diam. 10 mill."; figured specimen herein H 23.7, D 10.06, W 6.3.

Type material.

NHMUK 1878.1.28.209, lectotype (H. Adams coll.).

Remarks.

Adams did not state on how many specimens his description was based. The specimen was designated as lectotype by Breure (1979: 123), but erroneously mentioned under Bulimulus aureolus rawsoni Guppy, 1871. Guppy’s shell was from the same source and his taxon was considered the senior subjective synonym of Adam’s taxon by Pilsbry (1899: 20).

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) rawsoni (Guppy, 1871).
