Type locality.

”Peru”.

Label.

"without locality, from the original series".

Dimensions.

"Height 8.2 mm., diameter 8.6 mm."; figured specimen herein H 7.2, D 7.6, W 4.9.

Type material.

NHMUK 20100630, four probable paratypes (ex Weyrauch).

Remarks.

Pilsbry and Olsson (1949: 10) remarked "paratypes 184900 ANSP and in Museo Historia Natural, Lima, where many specimens were preserved without locality". As it is known that Weyrauch worked in the Lima museum during many years in the 1940s-1950s ( Barbosa et al. 2008), and Weyrauch exchanged many shells, these specimens are considered probable paratypes. Of the supposedly five specimens originally sent by Weyrauch, one is missing and two are broken.

Current systematic position.

Bulimulidae , Bostryx metagyra Pilsbry & Olsson, 1949.
