The endcomb consists of from ten to thirteen distal teeth and five or six proximal teeth on both sidesof these. The distal wart on the dorsal chitinous plate of the distal cavity is of about thesame type as in the preceding species, its central tooth, however, seems always to have asingle point. In other respects this limb is similar to that of the preceding species. F u r c a: — This is very like that of the preceding species, with the same numberof claws, aU well defined from the lamellae. The fourth claw is usually somewhat short andweak comparatively, sometimes its weakness is even rather striking. The curvature of the. Fig. XXXVII. — r.

With regard to the other organs but little information can be given, as they were in sodamaged and dirty a condition in the only specimen accessible that it was impossible to carryout a detailed investigation with any certainty.
