Sukashitrochus dorbignyi

Sukashitrochus dorbignyi is a species of minute sea snail, a marine gastropod mollusk or micromollusk in the family Scissurellidae, the little slit snails.

[2][3] The thin, transparent, glassy, white shell is very small.

Under the rather elevated slit fasciole there are two elevated lirae, and the base has concentric lirae and grooves, while the usual growth striae are not lacking.

In the example figured in the "Description of Egypt" there is a deep groove between the keel and the upper of the two spiral lirae.

Dall) the groove is very shallow, and bears an elevated line.
