Etymology
Etymology. In reference to Bernoulli Island group, including the type locality, Latinized adjective.
Description
Description. Shell (Figs 3 A, 4 A, B). Diameter and height average; shape broadly conical. Whorls with slightly angulate periphery, moderately shouldered underneath suture. Axial ribs weak. Colour brownish-horn to light brown. Genitalia (Fig. 6 A). Penial length equivalent to Ń of anterior part of oviduct (= vagina and free oviduct). Inner penial wall posteriorly with three corrugated longitudinal pilasters, anteriorly with longitudinal folds extending into atrium. Vaginal about half as long as penis and free oviduct. Spermoviduct more than three times longer than free oviduct and 1.5 times longer than albumen gland.
Discussion
Remarks. Shell colour darker than other congeners except A. augustae and A. rotunda. On average smaller than A. augustae, A. crassicostata, A. pallida, A. rotunda and A. sanctumpatriciusae, larger than other congeners; more elevated than A. buffonensis, A. nana, A. sanctumpatriciusae and A. vulcanica, flatter than other congeners; with larger number of whorls than other congeners except A. augustae A. crassicostata and A. pallida. Sculpture finer than in A. augustae, A. sanctumpatriciusae, A. crassicostata, A. rotunda and A. nana. Inner penial wall sculpture similar to that of A. augustae but with corrugated longitudinal pilasters. This is Solem’s (1991) manuscript species 78, erroneously considered by Köhler (2011 b) as endemic to Coronation Island. However, this species has not been collected on Coronation Island but only on an unnamed island SE of it, on Bernoulli Island and on another small unnamed island E of the former. Additionally, in Köhler’s (2011; Fig. 1) map the two latter localities are erroneously labelled with ‘NSP 79 ’ (= A. crassicostata).
