Description

Shell, small, rather conic, white, with thirteen broadly reflexed, axially conspicuously striated varices; nucleus? (lost); whorls, more than six, varices continuous up the spire, narrow near the suture, more than doubling in width at the shoulder, where they are provided with a small spine or prominent angulation, then continuing to the base, where they are again narrowly contracted; there is no basal cord or disk, the umbilicus is closed; the surface of the whorls between the varices is smooth; the whorls are evenly rounded, and the aperture, if perfect, would probably be nearly circular. Length of six whorls (decollate), 9.5; diameter at base, 5.0, at decollation, 0.7; of aperture, 2.0 mm.
Though both the specimens of this species were dead, and more or less broken, it is evidently distinct from any other yet named from the coast, and for that reason it seemed desirable to describe it.
