Description
The length of the shell attains 22.5 mm, its diameter 17.9 mm.
(Original description) The very solid shell has an elongate-conic shape. It is contracted at the base, constricted and channelled at the suture. The
body whorl
The body whorl is part of the morphology of the shell in those gastropod mollusks that possess a coiled shell. The term is also sometimes used in a similar way to describe the shell of a cephalopod mollusk.
In gastropods

measures about half the total length. The shell contains eleven whorls, including the
protoconch
A protoconch (meaning first or earliest or original shell) is an embryonic or larval shell which occurs in some classes of molluscs, e.g., the initial chamber of an ammonite or the larval shell of a gastropod. In older texts it is also called ...
0 Its colour is pale ochraceons-buff, the
aperture lighter.
Sculpture: The body whorl contains thirteen, penultimate with four, and earlier whorls with three prominent spiral keels. The furrows between carry faint radial striae, and sometimes a small interstitial thread.
Aperture: there is a thin callus sheet on the inner
lip, and a solid callus plug at the angle of the aperture. The outer lip is simple. The sinus has a semicircular notch with reflected margin. The
siphonal canal
The siphonal canal is an anatomical feature of the shells of certain groups of sea snails within the clade Neogastropoda. Some sea marine gastropods have a soft tubular anterior extension of the mantle called a siphon through which water is ...
