Seguenzia is a genus of sea snails, marine gastropod mollusks in the family Seguenziidae.^[2]

This genus was named after Giuseppe Seguenza (1833-1889), the palaeontologist at Messina, Italy.

Description

The thin shell has a turbinate or subtrochoid shape. It is translucent, the outer layer very slight, somewhat nacreous in fresh specimens. There is no epidermis. The shell contains spiral carinations. The upper part of the body whorl is deeply and widely grooved. The aperture is irregular and sinuous behind. The columella is twisted and abruptly notched below. It has a small tooth-like process. The base of the shell shows a sinus. It is deeply umbilicated or imperforate. The thin operculum is oval, with a subcentral nucleus and with obsolete, numerous concentric lines.^[3][4]
