Surface of these lobules are covered with small granules and scattered, short, dark, stiff hairs. The exposed surfaces of the chelipeds and legs are granular and bristly, like carapace; and the carpal joints, and to a less extent the propodites are dimpled, but not distinctly nodular above. Under surface of carapace granular, hairy and furrowed by grooves continued from fissures that subdivide the antero-lateral borders into four shallow lobes.
