The capitulum with very thin walls; slightly transparent. Carinal margin evenly arched; occludent margin straight and slightly protruding along the orifice. On either side near the orifice a pair of distinct but imperfectly calcified scuta. Each scutum consists of a narrow band along the occludent border with two divergent lobes-ones bending towards the base of the orifice, the other comparatively broader, away from it. The orifice is large, occupying a little more than half the length of the capitulum and continued as a superficial slit in the outer valve nearby. Folds of lips delimit the orifice on either side, outer integument surrounding the capitulum smooth and without tubercles, hairs or tactile organs.
