Type locality.

"[Eastern Peru]".

Label.

"E. Peru", taxon label in H. Adam’s handwriting.

Dimensions.

"Long. circa 45, diam. 17 1/2 mill."; figured specimen herein H 39.1, D 18.2, W [1.3].

Type material.

NHMUK 1867.5.18.3, holotype, Bartlett leg. (ex H. Adams).

Remarks.

As is shown in Adam’s figure, his shell ("one example of this beautiful species") was badly broken, with only the lower part of the shell remaining. The shell height he gave was clearly a guess, as the actual shell is smaller. The lot is accompanied by a photo "of [a] perfect specimen from H.B. Preston"; assuming that this photograph is natural size, the dimensions are H 58.1, D 21.0. The current systematic position follows Richardson (1995: 165).

Current systematic position.

Bulimulidae , Drymaeus (Drymaeus) pulcherrimus (H. Adams, 1867).
