The surface of Ventridens cerinoideus’ is shell is glossy, with weak radial striations. The shell has a pale yellow color. The lip is dilated slightly at the point where it meets the axis, nearly covering the umbilical perforation. The shell is similar in shape to other Ventridens, though it is almost always smaller than V. gularis, and its apex is lower. Two teeth are present in younger specimens, but are lost just before maturity.

This coastal species is found in floodplains, swamps, and marshes, and on roadsides, usually under litter.

Taxonomy
Synonyms for V. cerinoideus are: Helix cerinoidea, Ventridens gularis cerinoideus, Zonites cerinoideus, and Zonitoides (Ventridens) cerinoideus.
