Homonymy
[edit]Junior homonym of Aclis angulata P. Fischer, 1869.
Description
[edit]The length of the shell attains 2 mm, its diameter 0.75 mm.
(Original description in Latin) The shell is small, elongate, and turreted, with a smooth white surface and composed of six whorls. The first two whorls are large, convex, and smooth, transitioning to subsequent whorls that are obliquely sloping above, sharply carinate-angular at the midsection, and constricted below the angle. These later whorls are adorned with prominently elevated, closely spaced, and regular growth lines.
The body whorl exhibits a very obtusely rounded-angular profile at the periphery. The aperture is oblique and irregularly ovate, with a continuous, non-thickened peristome that is subtly sinuate above the angle near the suture.
This little species is remarkable for its angular whorls, the regular close-set raised lines of growth, and large apex. [2]
Distribution
[edit]This species has occurred in the Atlantic Ocean off Saint Helena.[1]
