Color: Greenish with white dots sometimes united into longitudinal lines. Ground color brownish green, marked in one with light longitudinal lines, and with small white sports, arranged in fairly regular rows.

The lateral lamellae are whitish with green perfoliations. The lateral lamellae are whitish and about 30 on either side: in the branchial cleft are about 25 white lamellae. There is no caruncle but a few projections in front of the rhinophores.

The shape is squarish and clear-cut. The jaws are rather long and narrow with about 8 rows of denticles, which are especially plain on the masticatory process. The broad and high central tooth bear about 5 ridges and denticles on both side. The other tooth bares about 8 denticles, decreasing in number outwards until there are only one or two. The nine outermost teeth are smooth.
