Shell small, stout, white, with prominent umbones; produced and rounded before, shorter and pointed behind, with close, strong, subequal, uniform concentric ridges; base rounded, slightly concavely waved in front of the angle of the rostrum, corresponding to a marked depression in front of an equally prominent ridge which extends from the umbo; the concentric ridges are about equal to their interspaces; there is a pale yellow concentrically finely wrinkled epidermis; the tips of the umbones are full, smooth, and polished; there is a lanceolate, smoothish lunule bounded by an obscure ridge, and a shorter and narrower escutcheon bounded by a faint ridge, outside of which is a faint depression; on either side of the beaks is a narrow, flattened area, recalling that of Limopsis, but much smaller and narrower; in the middle of this, just under the beaks, is a very small socket for the ligament, which is wholly external to the line of the teeth, just as in Palaeoneilo there are eleven developed and three obsolete anterior teeth and about twelve posterior teeth, of which two or three are very small; the two sets are separated by a very narrow, smooth space, but there is no cartilage; the muscular scars are deep, the pallial line obscure, the margin simple, and the valves rather thick; maximum longitude of shell 5.5; maximum altitude 4.5; diameter 3.1mm; the beaks are over a point on the line of maximum length, which is 3.25mm from the anterior end.

Caribbic. South from St. Kitts and East from Tobago.
