«Shell small, thick, moderately convex, entirely smooth except for very fine growth lines; ears sub-equal, large, sub-triangular; juncture of ears with shell slightly depressed, but not otherwise marked off. The interior of the valve is inaccessible, but there seem to be no Internal rlbs or else very obscure ones. They do not show on the exterior, and there are no radial rays or striations of any sort. The shell is unusually solid. It is probably related to A. luna Brown and Pilsbry, and to A. mortoni Ravenel, but differs from these in Its small size and relatively much larger ears. Length 19 mm., height 19.5 mm., semi-diameter 3 mm.
A single left valve, which was at first included with the specimens of A. papyraceum, Dr. Maury, in looking over the specimens, pointed out the mistake. Locality.— Collazo Falls. Horizon.— San Sebastian shale.» BELA HUBBARD, 1920
