Bembicium is a genus of sea snails, marine gastropod mollusks in the family Littorinidae, the winkles or periwinkles. [1]
(Described as Risella) The depressed shell is trochiform, with flattened whorls and a keeled periphery. The shell is not umbilicated. The aperture is rhomboidal, marked with brown inside the margin. The operculum is paucispiral.
These shells are distinguished from Trochus , which they resemble in form and sculpture, by their non-nacreous interior. The animal is distinguished by eyes on the tentacles instead of on peduncles, and by the absence of the lateral membranes of the foot. [2]
The following species are recognised in the genus Bembicium:
Dosinia is a genus of saltwater clams, marine bivalve molluscs in the family Veneridae, subfamily Dosiniinae Deshayes, 1853. The shell of Dosinia species is disc-like in shape, usually white, and therefore is reminiscent of the shells of Lucinid bivalves.
