Naquetia annandalei

Naquetia annandalei is a species of sea snail, a marine gastropod mollusc in the family Muricidae, the murex snails or rock snails.

Description

The shell is fusiform and reaches a length of about 76.5 mm, with a reported maximum size of up to . It is pale reddish-brown, marked with indistinct chestnut bands.

The spire consists of approximately 9½ whorls. The shell bears three foliaceous varices along its length, the first two forming hollow spines. The remaining whorls have a somewhat rough (scabrous) appearance, sculptured with fine beaded spiral striae and transverse nodulous ribs. The sutures are impressed and coarsely crenellated by the terminations of the transverse ribs.

The columella is slightly curved, white, and expanded. The outer lip (labrum) is nearly continuous, reflexed, and whitish, with three widely spaced chestnut spots corresponding to the termination of the colour bands. The aperture is oval, with a notch at the junction of the outer lip and parietal wall.

The siphonal canal is elongated, closed, and recurved anteriorly. The margin is nearly erect and extends into a thick, well-defined white callus bearing an indistinct nodule.
