Description

The shells of these very common cowries reach on average 32–38 millimetres (1.3–1.5 in) of length, with a minimum size of 17 millimetres (0.67 in) and a maximum size of 56 millimetres (2.2 in). The dorsum surface of these smooth and shiny shells is generally pale brown or yellowish, with several small white spots. The base is white or pink, with several fine teeth. In the living cowries the mantle is pale brown and greyish, with long tree-shaped sensorial papillae. This species is quite similar to Naria lamarckii, but in Naria miliaris the edges of the shell are white, without any spots.
