Description

The back and sides of this slug are brownish and darker, with some brown and yellowish spots. Near the foot the body is yellowish, with a greenish or orange hue.

The points of origin of the lateral grooves are about 5 mm apart at the mantle; they are not joined. The sole is yellowish. The shell rudiment is located on the posterior section of the dorsum. It is almost parallel-sided and large, with its apex pointing downwards, and the basal end of the aperture pointing upwards. The shell is greenish or brownish with two whorls and a keeled suture. Animal 6–12 cm, shell 13-17 x 7-11 x 3.5-3.5 (height) mm.[3]
