Alcithoe lutea

Alcithoe lutea is a species of large deepwater sea snail, a marine gastropod mollusc in the family Volutidae, the volutes.

The length of the shell attains 85 mm, its diameter 38 mm.

(Original description) The shell is fusiform, robust, pale buff with a high, blunt spire. It features a relatively large aperture, a slightly reverted outer lip, and four teeth on the columella.

Sculpture:

The color of the shell is ashy white over pale buff, completely matte. The outer lip and body glaze are rich buff, becoming paler inward.

The spire is high and slightly irregularly bent, subscalar with a blunt, mamillary, and with an impressed apex.

There are 6¾ convex whorls, contracting above into the suture, and perpendicular below. After the first three, the whorls increase rapidly in size. The body whorl is slightly ventricose, long, and attenuated in front. The suture is oblique, slightly impressed, and irregular.

The aperture is long, but not wide. It is oblique, with nearly parallel sides. It is bluntly pointed above, ending in a broad, shallow, slightly emarginated canal with a minute border at the base.
