Dimensions.

"Long. 19, diam. 9 mill."; figured specimen herein H 18.8, D 9.28, W 6.2.

Type material.

NHMUK 20100564, one possible syntype (Cuming coll.).

Remarks.

A lot was found under this name, containing two specimens. One specimen corresponds to the measurements given by Pfeiffer and to Reeve’s figure; it is, however, not accompanied by a taxon label in Pfeiffer’s handwriting, and therefore considered a possible syntype. The other specimen belongs to a different species, viz. Kuschelenia (Vermiculatus) anthisanensis (Pfeiffer, 1853), and is here excluded from the type series. The current systematic position follows Richardson (1995).

Current systematic position.

Bulimulidae , Naesiotus quitensis (Pfeiffer, 1848).
