Description
Max. size: 18 x 4 mm

Color: The animal is translucent, closely stippled with fine dark dots on pale cream, giving a general appearance of pale brown: the viscera can be clearly seen through the surface, above and below. Rhinophores are of the same color as the body and are finely stippled with dark spots.

The mantle is wider than the foot, rolled and thickened at the edges, which meet behind the gills to continue along the tail as a dorsal median crest. In the median line of the mantle is a low ridge, consisting of four tubercles, of which the hindmost, lying in front of the gills, is the largest. These tubercles show more distinctly in a spirit specimen than in the living animal. Slightly in front of the foremost tubercle are the rhinophores; the upper half has about ten deep-cut coarse oblique laminae and is surmounted by a prominent plain apex. The bases below the laminae are pale and transparent.
The rhinophores do not retract, but contract slightly on touch: no sheaths are present. The head is produced laterally into tentacles. The gills, three in number, are tripinnate. The raised anal papilla is surrounded by an elevated sheath, whence three low ridges lead to the rhachides of the three gills. The tail is long and pointed. The sole is of the same color as the dorsum. The front may be extended and convex or may contract into a bilobate curve, concave in the middle. The radula has a large inner lateral and a much smaller outer lateral.
Formula, 26 X 1.1.0.1.1.
