Assiminea cornea is a species of small operculate snail, a marine gastropod mollusk or micromollusk in the family Assimineidae. [1]
This is a taxon inquirendum.
Description
The length of the shell attains 4 mm, its diameter 3 mm.
(Original description in Latin) The shell is subobtectly perforate (sometimes imperforate), conoid-ovate, and horny in texture, smooth, with an oily shine, and is scarcely striate.
The spire is cone-shaped, with convex sides and an sharp apex. The impressed suture is not margined. It has six convex whorls, which increase gradually. The body whorl is rounded below and not keeled.
The aperture scarcely equals the height of the spire. It is suboval, oblique, and openly angled above. The peristome (margin) is straight, with a thin outer lip. The inner lip is thickened and somewhat expanded, covering the umbilicus partially or entirely.
The operculum is corneous, with few spirals, and has a subbasal, internal nucleus. [2]
Distribution
This species occurs in brackish waters off Mumbai, India; also off Taiwan.
