Folinella excavata is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies.[2][4]
Description
The white shell is solid, opaque and rather glossy. Its length measures 3.75 mm. The teleoconch contains six whorls. The suture is broad and very deep. The shell shows prominent spiral ridges, of which there are three on the main part of the body whorl, and two slighter ones at the base, and two ridges on the spire whorls. They are crossed obliquely by sharp longitudinal ribs, extending to the base. Their intersections with the spiral sculpture appear nodulous. The columellar tooth is small and remote. The umbilicus is narrow but distinct.[3]
