The shell is moderately small and slender. The
protoconch consists of about 2½ smooth
whorls. The outer
lip is varicose, extending forward. The channel across the
basal lip is shallow, slightly undercutting the
columella. The parietal wall is callused, forming a channel with the outer lip. The
sculpture consists of fine axial
ribs, between which lie fine spiral threads. Aside from the difference in sculpture, the outer lip is more flaring than in Rissoina s. s., and the channel across the basal lip is wider and shallower, and does not undercut the columella so strongly.[2]
