editThese very common small shells reach on average 15–23 millimetres (0.59–0.91 in) of length, with a maximum size of 36 millimetres (1.4 in) and a minimum size of 8 millimetres (0.31 in). The basic color of the shell is orange-brown or beige, with many white dots on the top of the dorsum. The underside is orange-brown. In the living cowries the mantle is transparent, with short white papillae.
