is turreted. The whorls are covered with a sutural cord and have a smooth, slightly concave shoulder The periphery is nodulous with the terminations of oblique, longitudinal ribs, which are crossed by strong revolving lines. The labium
has a very strong projecting superior callus. The outer lip is winged, with a second small sinus indicated towards the base. The siphonal canal
is short.

Description
The size of an adult shell varies between 20 mm and 60 mm. The shell is yellowish white or brownish, usually interruptedly broad-banded above and below the middle of the body whorlBody whorl
Body whorl is part of the morphology of a coiled gastropod mollusk.- In gastropods :In gastropods, the body whorl, or last whorl, is the most recently-formed and largest whorl of a spiral or helical shell, terminating in the aperture...

Spire (mollusc)
A spire is a descriptive term for part of the coiled shell of mollusks. The word is a convenient aid in describing shells, but it does not refer to a very precise part of shell anatomy: the spire consists of all of the whorls except for the body whorl...

Siphonal canal
Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is drawn into the mantle cavity and over the gill and which serves as a chemoreceptor to locate food. In many carnivorous snails, where the siphon is particularly long, the structure...
