Shell small, white, depressed, oval, very thin, broader towards the front, the ends slightly raised, front and side-slopes slightly convex, posterior slope nearly straight, with a very small impression below the nucleus, this latter smooth, compressed, subspiral, placed at a little more than 6/11 of the total length of the shell. Sculpture consisting of a few concentric striae, moreover the whole surface is covered by very small, crowded granules of an irregular oval, potatolike shape, sometimes two or three granules are confluent, they are placed in oblique rows. Inside smooth. Long. 5,5 mm, lat. 3,5 mm, alt. 1 mm.

The shell of this species, in every respect, save sculpture, calls in mind the species of Cocculina. As the animal was not in a sufficient state of preservation, I could not observe the external characters, but a look at the radula, shows at once that this species is congeneric with the preceding one, and quite different from Cocculina. The rhachidian tooth (R) has an oblong shape, with convex sides towards the middle, concave towards the top, with slightly reflected margin, the upper margin without cusp, but irregularly convex; about the centre of this tooth, an irregular spot seems to be thickened and slightly coloured (one could think, this is the cusp, were it not that in the allied species, a similar spot stands quite near the base) the first lateral (1) has a subtriangular shape, with a thickened or reflected upper margin, followed by three laterals, (2, 3) of a shape similar to those of the preceding species, with a simple cusp, the outermost lateral (5), is so much concealed by the large uncini, that its shape could not be traced, it seems to have a simple cusp, without the sharp denticle of the preceding species. The proximal uncini (U) are strongly hooked and simple, the median ones seem to be serrated and the exterior one again simple.
