Description

The shells of these quite uncommon cowries reach on average 25–30 millimetres (0.98–1.2 in) of length, with a minimum size of 14 millimetres (0.55 in) and a maximum size of 57 millimetres (2.2 in). They are oval and have a medium thickness. The dorsum surface of these smooth and shiny shells has generally a fawn or cream color and it is spread with numerous white spots, a few of them with a black centre (hence the Latin name ocellata). The base is whitish and often has a brown blotch, while the pronounced margins show various fawn spots on a pale background. In the living cowries mantle and foot are well developed, with external antennae.
