Description

These very common shells reach on average 20–28 millimetres (0.79–1.10 in) of length, with a maximum size of 45 millimetres (1.8 in) and a minimum size of 13 millimetres (0.51 in). The dorsum is usually pale brown or greenish, with very variable patterns of darker greenish trasversal bands or spots. The base and the teeth of the aperture are white. In the living cowries the papillose greenish mantle grants the camouflage.
