Amalda dimidiata is a species of sea snail, a marine gastropod mollusk in the family Ancillariidae.[1]

Description

[edit]

(Original description in Latin) The thin shell is elongated. It is white with a tawny tint above the suture. The spire is elevated, with whorls that are gently rounded. A callous layer extends to the midpoint of the body whorl, featuring a doubled lower band. The outer lip bears a single tooth, while the varix is elongated, narrow, and grooved.

This thin, pale species presents a medium in respect of the extension of the spire-covering enamel, which reaches nearly halfway down on the body whorl. [2]

Distribution

[edit]

This species occurs in the Atlantic Ocean off Brazil.
