Two very small rostral teeth. Fingers of male widely gaping. Description.—Carapace depressed; partially granulate, especially along the posterior margin, on the summit of the cardiac region and the outer two-thirds or more of the branchial regions; a few granules on the front, on the middle of the gastric region and on the outer margin of the hepatic region. Amount of granulation varia- ble. Rostrum bluntly triangular, tip cut into two minute teeth. Post- orbital lobes small, directed straight outward and much exceeded by the ej^es. Sternum of male coarsely granulate except between the chelipeds; abdomen nearly smooth save for the boss at either side of the third segment and the spine or tubercle on the first segment. Abdomen of female covered with depressed granules. Basal article of antenna with margins almost unarmed, the outer one finely roughened, the inner margin not exceeded by the outer one. Merus of chel- ipeds with denticulate margins, chela dilated in male, fingers Avidely gaping for their proximal fifth, this portion of the fixed finger being curved downward and excavate, a triangular tooth at end of gape; a broad, low tooth projects from the dactylus into the middle of the gape.
