Shell stout, solid, fusiform, waxy white, with nine whorls ; nucleus brown, smooth, first three (nuclear) whorls sculptured with neat flexuous ribs transversely disposed ; next four whorls transversely with only the rather strong and distinct rounded lines of growth which cover pretty much all the rest of the shell except the tops of the longitudinal riblets ; the longitudinal sculpture a keel just in advance of the suture upon which the posterior edge of the former is appressed, then a few faint revolving striae on the broad notch-band, then two more keels, or sharp squarish riblets (on the last whorl ten or twelve), the first marked with numerous knobby waves extending forward in the interspace toward the second keel rather than outwardly, and sometimes meeting and slightly waving the second keel ; these waves make their appearance on about the fifth whorl, and are evanescent on the last whorl ; there are about three in a millimeter and a half; aperture narrow, slightly callous ; canal short, nearly straight ; pillar covered with thin, translucent white callus ; outer lip not thickened, but might become so in an older shell. Lon. of shell. 13.0 mm; of last whorl 8.0 mm; of aperture 6.0 mm. Max. lat. 5.0 mm. Defl. about 42°.

A solid, stout, clear-cut species, allied to Drillia Kennicuttii Dall, of Alaska, but shorter and more spindle-shaped.

Caribbic.
