The shell has a narrowly fusiform shape. Its surface is rather dull and blackish-fuscous. It contains 11 whorls, of which the apical are smooth, shining, apparently carinate centrally, but the type specimen is a little worn and imperfect in this particular. The lower whorls are suturally impressed just below the sutures, at the summit of each whorl, once spirally acutely keeled, the remaining portion being rather ventricose, longitudinally obliquely multicostate, crossed by, on the four penultimate whorls, three to five spiral revolving lines, gemmulate at the several points of junction with the ribs. The gemmules are shining, often pale. The body whorl possesses fourteen such lirae, with over twenty closely grained ribs. The aperture is narrow and oblong. The outer lip is not effuse, columellar nearly straight, the sinus shallow, but well expressed. The siphonal canal is slightly recurved.[2] DistributionThis species occurs in the Caribbean Sea from Panama to Suriname References1. ^1 {{WRMS species|432646|Crassispira chazaliei (Dautzenberg, 1900)||4 April 2010}} 2. ^Proceedings of the Malacological Society of London v. 14-15 (1923) (described as Drillia anthamilla )
