Shell rather small, white, patelliform, oblong, compressed, moderately elevated, the ends broadly rounded and conspicuously elevated, sides subparallel, being slightly broader in front. The anterior slope, which is a trifle longer than the posterior one, is slightly convex, the posterior has a small depression near the apex, and is from thence nearly straight, the side slopes are decidedly convex. The apex is subcentral, with a subspiral, compressed nucleus, which is smooth even under the lens. The shell is covered by a rather thin, yellowish, fibrous epidermis, which is conspicuously wave-striated. Sculpture of the shell consisting of elevated radial striae, which are crossed, at irregular intervals, by concentric striae, these latter are more crowded near the apex. Inside of shell smooth, white.
Long. 6,85 mm, lat. 4,75 mm, alt. 2,5 mm.

This species might be mistaken for the young of C subquadrata Schepman, but its shape is more regular, it is much less depressed, the epidermis is much coarser, the sculpture more conspicuous. The rhachidian tooth (R) of the radula is much elongated, with subparallel sides, however the body is broader towards the anterior margin. It has a small, simple cusp, the anterior and side margins are thickened. The other teeth have the usual shape, the first (1) and second (2) laterals have a cusp with three small denticles, the cusp of the third lateral (3) is simple. That of the fourth (4), if seen in situ, has the usual large cusp, with a small secondary one. If turned outwards it has on the other side of the chief cusp, still two smaller ones. I think however this will be the case in many of the described species, as I have often observed it more or less distinctly. The uncini (U) have a few small denticles, better visible in reversed teeth.
