Species of a large size; carapace obtusely pentagonal in out line; anterior border of merus of ambulatory legs armed with 4 to 6 obtuse spines.

Carapace somewhat pentagonal; its length not quite ¾ its breadth; surface deeply eroded, strongly rugose, and sharply tubercular. Its postero-lateral angle much produced outwards. Antero-lateral margin coarsely spinate. Posterolateral and posterior margins granular, the former with a coarse spine. Rostrum short, moderately deflexed, ending in a blunt inter-antennulary tooth. Orbits circular, deep. Chelipeds huge, one much larger than the other, the larger twice the length of the carapace (in the female), covered with large coarse granular spines. Ambulatory legs stout, spiniferous; the dactylus smooth. The meropodite in all is compressed-trigonal, with all the edges spinate. The under surface of the body has a worm eaten appearance. The sternum is deeply pitted, with a deep crescentic excavation between the chelipeds.
