Zebinella is a genus of minute sea snails, marine gastropod mollusks or micromollusks, in the family Rissoinidae.[1]

Description

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]
