Bulimulus (Drymaeus) trinitarius E.A. Smith 1896: 242, pl. 8 figs 7-7a.

Type locality.

”[Trinidad]”.

Label.

”Trinidad”.

Dimensions.

"Longit. 19 millim., diam. 9"; figured specimen herein H 20.1, D 9.84, W 6.1.

Type material.

NHMUK 1875.2.8.2, lectotype and one paralectotype; 1866.1.3.13 (part), ten paralectotypes, both R.J.L. Guppy leg.

Remarks.

Smith remarked "the only two adult specimens I have seen". Pilsbry (1899: 19) already recognized that this taxon was a junior synonym of Bulimulus multifasciatus imperfectus Guppy, 1866. Type material of the latter taxon-though expected in the NHMUK-was not found. One specimen of lot 1875.2.8.2 corresponds to Smith’s fig. 7a and is here designated lectotype to define the taxon. The specimens of the other lot are all juveniles.

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) imperfectus (Guppy, 1866).
