Description

This genus is characterized by a depressed, openly umbilicated, smoothish shell. The peristome is obtuse. The columellar margin is dilated, partly vaulting over the umbilicus, which is radially sulcate within and has a very low, wide and rounded marginal cord.

This genus comprises species related to Monilea, Ethalia and Isanda, but with features of the columellar lip and umbilicus unlike either. Minolia and its boreal ally Solariella differ by the almost or quite unexpanded columellar margin.[3]

Distribution

This marine genus occurs off Japan, the Philippines and in the East China Sea.
