Type locality.

Label.

”Brazil” and ”Venezuela” (see remarks), taxon label in Pfeiffer’s handwriting. M.C. label style IV / I.

Dimensions.

"Long. 12 ´´´. Diam. 6 ´´´ [H 26.1, D 13.0 mm]"; figured specimen herein H 23.5, D 12.95, W 6.2.

Type material.

NHMUK 1975542, lectotype and two paralectotypes; 20120333, one probable syntype (Cuming coll.).

Remarks.

According to the labels of lot NHMUK 1975542, the specimens would have originated from Brazil. This is probably an erroneous Cumingian label, as the species has only been found in Colombia (Breure and Borrero, unpublished data). A label stating " Bul. helena Quoy" and a second, illegable, label have supposedly been added afterwards. Another label makes clear that one of the specimens was figured by Reeve (1848). As the taxon label is written by Pfeiffer, there is little doubt about the type status of the specimens in this lot. The shell figured by Simone (2006) is a juvenile syntype. Another lot, NHMUK 20120333, was found with locality ”Venezuela” (striked-through in pencil), of which the largest specimen is said to originate from the Cuming collection. As this lot also has a taxon label in Pfeiffer’s handwriting, the specimen is considered another probable syntype. It is assumed that the original measurements were given in German lines. The largest specimen in lot NHMUK 1975542 is here designated lectotype (design. n.) to fixate this taxon, which seems to have been misinterpreted in most cases (Breure and Borrero, unpublished data).

Current systematic position.

Bulimulidae , Drymaeus (Mesembrinus) nigrofasciatus (Pfeiffer in Philippi 1846).
