The length of the shell attains 11.5 mm, its diameter 4.5 mm. (Original description) The small shell is waxen white, superficially resembling
Oenopota granitica (
W. H. Dall, 1919), but differing in the following particulars: It has one rib less; the two prominent spiral cords on the early
whorls are strongly nodulous when they cross the ribs, especially the posterior cord, even on the
body whorl. The spiral
sculpture on the body whorl in front of the fasciole comprises 10 strong flattish cords, separated by very sharp, narrow grooves, with no spiral sculpture on the back of the
siphonal canal, which is distinctly shorter. The
aperture is relatively shorter and wider. The
protoconch is apparently similar but eroded, the number of whorls is the same but the shell is shorter. ==Distribution==
