Description

The height of the shell attains 2½ mm, its diameter also 2½ mm. The minute, umbilicate shell has an orbiculate-conoid shape. Under a lens it is longitudinally striate. It is shining, whitish, painted with oblique chestnut streaks, and spotted with brown. The apex is rather obtuse. The five whorls are regularly increasing, rather convex, and flattened at the distinctly impressed sutures. The body whorl scarcely equals half the total altitude. The base of the shell is rounded or obscurely subangular. The aperture has a quadrate-rounded shape. The simple peristome is acute. The columella is subtruncate at its base. The umbilicus is rather narrow and funnel-shaped.[4]

Distribution

This species occurs in the Red Sea. It also occurs in the Mediterranean Sea off Israel as an introduced species.

gollark: You mean, you need to catch another, or you need another even rarer one to get 5000 of?
gollark: Of course, the BSA could just be given to chronoxenos.
gollark: That would actually be quite useful.
gollark: An alt checker, if you will.
