SHORT DESCRIPTION
Shell ovoid, solid, tapering anteriorly, smooth and glossy. Aperture surrounded by a moderately thickened porcellaneous callus and extending along the whole length of the shell. Outer lip curled in and with ca. 15 denticles on the inner side, columellar edge with another row of folds which extend over the callus.

color : buff with small brown specks all over the dorsal surface, and three indistinct spiral brown bands; callus around the aperture buff with brown spots (larger than on dorsal surface), without marks near the siphonal canal.

common size : 20-25 mm.

DISTINGUISHING CHARACTERISTICS
The shell of Erronea caurica, once reported in the Mediterranean but which we reject as such, is similar but more cylindrical in shape, less piriform. Also, the dorsal side of E. caurica is usually more greenish, with three darker spiral bands.

BIOLOGY / ECOLOGY
Unknown.

habitat : unknown; the Mediterranean specimen was found at a depth of 20 m.


1st Mediterranean record

Worldwide: Northwestern Indian Ocean, Red Sea and Persian Gulf. Mediterranean: known from a few findings from Israel: recorded first in 1989 from Tel Aviv as Cypraea lentiginosa (Mienis, 1990).
