Marshallena nierstraszi

Surcula nierstraszi Schepman, 1913 Marshallena nierstraszi is a species of sea snail, a marine gastropod mollusk in the family Marshallenidae[1] The length of the shell attains 25¼ mm, its diameter 12¼ mm.

(Original description) The thin shell is broadly fusiform, with a rather short spire.

The six remaining whorls, of which the upper one is likewise eroded, are angularly convex, and slightly excavated below the deep suture.

Just below the suture, the shell is covered with fine growth striae and spiral lirae, these lirations being faint in the excavation, stronger and crowded in lower part of whorls, more remote on the siphonal canal; the body whorl attenuated below, passing without marked limit in the rather short canal.

The columellar margin is concave above, directed to the left along the siphonal canal, with a thin layer of enamel.
