Testa solida, cinerea, per-inequilateralis, costis ad 40 acutis, compressis, 
majoribus et minoribus alternantibus radiata, et striis concentricis confertis 
muricata; apice elevato, acuto, adunco, prorsum spectante: fissura lanceo- 
lata: apertura ovata; margine sulcis inequalibus alternantibus crenulato: 
facies interna porcellana; fornice tenui, simplici, arcuato. Long., y%; lat., 
% G ; alt., 54 poll. (Gould.) 
Shell rather solid, ovate at the base, and rising to form an elevated, 
oblique cone, having the apex at the posterior fourth of the shell, so that 
the anterior slope is moderate, while the posterior slope is nearly vertical. 
The apex is prominent, acute; reaching forward like a curved beak. The 
color is dirty cinereous. The surface is radiated by sharp, prominent, com¬ 
pressed ribs, which are alternately larger and smaller, to the number of 
about 40; and these are crossed by very fine and crowded concentric lines, 
by which they are delicately muricated. Fissure narrow, and narrowing 
upward. The interior is porcelain-white; the edge is beautifully crenu- 
laled by regular furrows, alternately longer and shorter, deeper and shal¬ 
lower, answering to the external ribs. The fissure is rounded, and the vault 
enclosing it is thin, simple, semicircular, and without callus at the summit.
