Popis

Shell of medium size and inflation, whorls nearly straight sided, interrupted mainly by the nodose peripheral carina. Protoconch small, subnaticoidal and tilted. Aperture moderately narrow, about half the length of the shell. Outer lip thin, broken on the specimens at hand, but shown by growth lines to recurve sharply into the anal sinus. Anal sinus moderately broad and deep, adjacent to the suture, the growth lines recurving only slightly from the apex of the sinus to the suture. Sculpture consisting of short axial nodes on the periphery, about ten of the peripheral nodes visible from an angle; lower part of body whorl and columella bearing weak raised spirals which are wider near the periphery, narrower and nearly obsolete on the columella; peripheral nodes crossed by both the spiral sculpture and diagonal lines of growth; subsutural slope smooth and flat except for lines of growth marking former positions of the anal sinus, and the small tubercles or wrinkles just below the suture on the juvenile whorls'

Taxonomie

The generic location of this species is provisional. The author compared it with both Paracomitas castlecliffensis and Comitas allani but noted the atypical protoconch which is small, subnaticoidal and only the last quarter turn is slightly angulate, not carinate.
MacNeil (1960, p. 106) mentioned a closely related Recent species from the Gulf of Boni, 484 fathoms, Celebes, but I have not seen this material.
