Description
Three large pearl-like tubercles on the posterior border of Carapace. Merus of ambulatory legs strongly foliaceous.

Carapace symmetrically sculptured, closely crisply and finely granular, and with the hepatic regions deeply excavate. There are three coarse spinules, disposed in a triangle base outwards. The posterior margin consists of three smooth polished globules exactly resembling pearls inset. The rostrum is long, vertically deflexed in both sexes, and incurved at the tip, which ends in two shallow lobes. The outer angle of each lobe being marked by a spinule. The chelipeds in the male are a little longer than the carapace, and have the palms broadened and inflated, and the fingers closely apposable only at the tip. In the female the chelipeds are very much slenderer than the other legs, are only as long as the post-orbital portion of the carapace, and have the hand very slender and tapering. The ambulatory legs are remarkable for their large obtriangular foliaceous meropodites.

The first pair of ambulatory legs are remarkable and closely apposable to the front, form a shield as in Calappa.
