Quinnia sykesi

Quinnia sykesi is a species of extremely small deep water sea snail, a marine gastropod mollusk in the family Seguenziidae.

[1] This species was named in honour of Mr. Ernest Ruthven Sykes, who has sent to M. Schepman for comparison a beautiful lot of specimens of this genus.

Two whorls next to the nucleus are crossed by conspicuous radiating riblets, straight but in an oblique direction above the keel, convex below it.

These riblets then suddenly disappear, only very fine striae succeeding them, being scarcely perceptible on the body whorl, which is bicarinate.

The base of the shell shows 7 spirals of which the distal one, separated from the third keel by a slightly concave space, and one bordering the umbilicus are stronger.
