Paracomitas Explained

Paracomitas is a genus of sea snails, marine gastropod mollusks in the family Pseudomelatomidae.

Description

The genus Paracomitas has a carinate protoconch which lies in the same cone as the spire, thus differing from typical Comitas in which the protoconch is noncarinate, bulbous and tilted. Although the type of Comitas, C. oamarutica (Suter), is Drillia-like in the ornamentation of its spire, some species referred to Comitas by Powell on the basis of the protoconch, such as Comitas allani Powell, are similar in adult sculpture to Paracomitas. The protoconch of the species here referred to Paracomitas is small and appears to be slightly tilted, and the last quarter-turn or less is slightly angulate, but not definitely carinate.^[1]
