Comitas kamakurana is a species of sea snail, a marine gastropod mollusk in the family Pseudomelatomidae.

The color of the shell is dull brown, with an ill-defined light band around the middle.

The whorls are very convex, almost angular, concave above and nearly smooth, appressed at the suture.

The shell is sculptured with numerous short vertical folds which do not extend on the body whorl below the level of the upper angle of aperture, and become obsolete on its latter half; and numerous subequal, crowded spiral cords throughout.

The aperture is nearly half the length of shell, long-elliptical above, passing into a long, open, straight siphonal canal below.
