Ancilla ovalis is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae.[2]
Description
The length of the shell attains 10 mm.
The shell is oval, white, and ventricose. The spire is produced. The aperture is rather short and unidentate (one-toothed) anteriorly. The columellar varix is small and sulcate, with the inferior band indistinct.
Reminiscent of Ancilla castanea, this small, white, and ventricose shell differs in having a much shorter aperture and a very small varix, while its basal belt remains indistinct.[3]
Distribution
This marine species occurs off Oman.
