Tudicla

Tudicla is a genus of sea snails, marine gastropod mollusks in the family Tudiclidae, the true whelks.

Description
The shell is fusiform. The spire is very short, the apex papillary. The aperture is oval. The siphonal canal is very long and straight. The columella is smooth, flattened and with a single fold at the fore part.

The papillary apex of the spire, the single plait on the columella, and the long straight beak, are the chief characteristics of this genus.
