Type material.

NHMUK 1975196, lectotype and one paralectotype (Cuming coll.).

Remarks.

According to Pfeiffer (1859: 443) the type is in "Mus. Cuming". The original specimen appears to be lost. The specimens are labelled "Bulimus con-/fluens Pfr. var. / Venezuela". There is no variety mentioned by Pfeiffer, nor in his original paper nor in subsequent publications, which is interpreted as him considering this a variable taxon; the specimens are thus regarded to be from the type series.

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) confluens (Pfeiffer, 1855).
