Shell small to moderate sized, 6-15 mm., fusiform, with the spire slightly taller than the aperture plus the canal, which is of moderate length, rather straight, and very shallowly notched. In general facies the genus is similar to both Guraleus and Neoguraleus,, but with one important difference, the protoconch, which is paucispiral, asymmetrical, of 1 ½ smooth whorls, papillate, the tip small and tilted, then rapidly inflated, more bulging on one side, clearly marked off from the adult sculpture, but without a brephic stage. Operculum absent. Radula consisting of a pair of long slender rather straight hollowed marginals, gradually tapered to a simple sharp point; the base a moderate hilt, with a conspicuous upcurved spur.
