Prosipho is a genus of sea snails, marine gastropod mollusks in the family Prosiphonidae, the true whelks. ^[2]

Description

(Original description by J. Thiele in German) I would like to create a new group under the name Prosipho.

Compared to the Nordic species, the Antarctic ones are significantly smaller; the largest specimen I have is not yet 12 mm high. All of them show a distinct spiral sculpture on the lower whorls. The lower canal has a very variable length. The initial whorl is usually smooth, sometimes uniquely shaped, but in two species, the upper whorls are covered with longitudinal folds. None of the species mentioned perfectly match the specimens I have.

A left-handed coiling species, of which I only have two empty shells, is so similar to the mirror image of some of these species that it is likely closely related to them.

Dall established the genus Antistreptus for a similar left-handed form which he placed next to Trophon . ^[3]
