Cryoturris

The shell is small or medium-sized, slender or moderately slender. The whorls are angulated at the periphery or rounded. The protoconch is slender or moderately slender, the apex generally rising abruptly, consisting of about 2 or 3 whorls. The body whorl or half whorl bears curved, protractive axial riblets and generally bulges at its periphery. The aperture is moderately narrow. The anterior canal is very short or hardly differentiated, slightly emarginate. The outer lip is simple, except at intervals corresponding to position of varix-like ribs. The anal notch is wide, shallow, or moderately deep. The sculpture consists of axial ribs, overridden by fine spiral threads and by microscopic frosted spiral threads. This genus is the tropical representation of the temperate genus Kurtziella with a similar aperture and sculpture. ==Species==
