Description
The spine at anterior angle of supraocular cave very small. Hepatic margin armed with a few tubercles, and the cardiac region with a single spine. Carapace armed with five long spines in the middle line. Rostral spines long and divergent, simple.

Carapace pyriform, convex, smooth, armed with five huge thorn like spines down the middle line, and with two even larger spines on the branchial region. The rostrum consists of two large divergent horns, the length of which is considerably more than half that of the carapace proper. The chelipeds in the female are slender, and are only equal to the post-rostral portion of the carapace in length. In the male the chelipeds are stouter than the other legs, especially as to the palm, which is considerably enlarged. The ambulatory legs decrease gradually in length from the first pair, which are equal in length to the carapace plus two thirds of the rostrum. The merus in the first two pairs has a very strong spine at the distal end of the upper border.

The body and legs in this species are somewhat hairy and are more or less encrusted with sponges, zoophytes, polyzoa etc.
