Alvania cancellata is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.[2]
Description
The length of the shell varies between 2 mm and 5 mm.
(Described as Rissoa crenulata) The imperforate shell is solid. It is opaque, yellowish white, tinted and indistinctly bifasciate with chestnut. The spire is mucronate. It is longitudinally broadly ribbed and strongly spirally lirate, the intersections forming strong rounded tubercles. The shell contains 6-7 convex whorls. The suture is widely channeled. The aperture is expanded, brownish red and sulcate within, subcanaliculate below. The outer lip is crenulately varicose exteriorly. The columella is tuberculated anteriorly. [3]
Distribution
This marine species occurs in the Mediterranean Sea (Corsica), in the Eastern Atlantic Ocean off Guernsey and Cornwall, English Channel, West Africa and off Madeira and the Azores.
Fossils were found in Pleistocene strata near Palermo, Sicily.
