Cymbiola flavicans

Cymbiola flavicans, common name the yellow volute, is a species of sea snail, a marine gastropod mollusk in the family Volutidae, the volutes.

Description

The size of the shell varies between 60 mm and 100 mm.

(Original description in Latin as Voluta signifer): An ovate-fusiform shell, very densely marked with longitudinal lines, somewhat yellowish in color, banded with irregular, interrupted chestnut-brown markings. The spire is of moderate size, slightly swollen, with a somewhat sharp, nipple-like, smooth apex. It has three whorls, the body whorl by far the largest and somewhat inflated. The lip is sharp, and the columella bears four large folds.

Two bands composed of detached, reddish-brown, irregular, interrupted spots encircle the spiral whorls, while three such bands, with a faint indication of a fourth, ornament the body whorl. A broad space separates the upper two bands of the body whorl from the third and the faint trace of the fourth. An irregular, linear streak of the same colour runs longitudinally and centrally, linking the upper three bands. Indeed, the colouring generally appears to flow from the upper to the lower band within each pair. The terminal notch is very deep and is crowned by an unusually prominent raised ridge.

Distribution

This marine species occurs off Papua New Guinea and Australia (Northern Territory, Queensland).
