Carcinological studies in the Leyden Museum

The cephalothorax of this rare species that occurs on the shores of Mauritius, is rather much enlarged and its lateral margins are armed with four teeth behind the external orbital angles which are not at all prominent. The first tooth is the largest, has the form of a bluntly rounded lobe and projects far beyond the external orbital angles; the second is somewhat smaller, and the third and fourth are the smallest, much narrower, and therefore appear more dentiform. The ambulatory legs are densely provided with long hairs. I examined this species in the Museum of Paris
