Steromphala spratti is a species of sea snail, a marine gastropod mollusk in the family Trochidae, the top snails.[2]
Description
The size of the shell varies between 5 mm and 8 mm. The somewhat thick, narrowly perforate shell has a conoid shape. It is whitish, radiately tlammulate with deep brown subquadrate maculations. The shell is very finely obliquely striate, and concentrically lirate. Each whorl is encircled by two more prominent, remote sulci. The shell contains 6 convex whorls, separated by deep sutures, and inflated above. The body whorl is subangulate, convex beneath, and contains numerous unequal concentric lirae. The aperture is rhomboidal. The slightly convex columella is sinuous in the middle.[3]
Distribution
This species occurs in the Aegean Sea.
