As Drillia anthamilla Melvill, 1923:
Shell narrowly fusiform, surface rather dull, blackish-fuscous, eleven whorled, 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; gemmules shining, often pale; the body-whorl possesses fourteen such lirse, with over twenty closely grained ribs. Mouth narrow, oblong, outer lip not effuse, columellar nearly straight, sinus shallow, but well expressed, canal slightly recurved.
Long. 34, diam. 9 mm.
Mr. Edgar A. Smith considered this species an ally of D. cernula, Angas, from Australia, but the coloration is different, it is larger, with the body-whorl also longer in proportion to the length of spire. To my mind D. maura, Sowerby, a West American species, is akin, but the ribs seem more numerous, and the revolving lines stronger and better developed in the last-named shell. From the figure also of D. appelii, Weink, one traces affinity, but this species is described as light-ochraceous in colour, and being indistinctly white banded. The general contour is, however, very similar.
