Alvania aequisculpta

Alvania aequisculpta is a species of small sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.

They show a sloping shoulder which extends over the posterior fourth between the sutures, marked by strong, slightly retractive, axial ribs which are about one-fourth as wide as the spaces that separate them.

The base of the shell is well rounded, rather short, produced anteriorly, and marked by three strong, sublamellar, spiral cords which are about one-third as wide as the spaces that separate them.

The parietal wall is covered with a very thick callus, which renders the peritreme complete.

[3] This marine species occurs off Southeast USA; Bahamas; Cuba; Colombia.
