Show 732 MR. w. r. LANCHESTER O N CRUSTACEANS [June 19, Antero-lateral margins curved, about as long as the posterolateral, divided into four lobe-like teeth, and tending anteriorly to be continued below' the orbits. Chelipedes short; arm trigonous, externally punctated like the carapace, upper margin sharp, lower rounded ; wrist punctate, armed internally with two approximate blunt teeth, externally with a line of three flat tubercles ; hand compressed, grooved externally and above, just below tbe blunt crest formed by the upper margin ; this groove is very wide and shallow, and not so conspicuous in small examples. Fingers brown, with white, strongly excavate tips; inner margins dentate; longitudinally bisulcate externally, uni-sulcate internally. Ambulatory legs with meri smooth, or slightly punctate ; compressed, and lightly keeled above. Upper borders of next two joints each with two tubercular prominences, one near the proximal, the other near the distal joint, Sixth joint rounded; dactyl very small and pointed. Abdomen of male five-, of female seven-jointed. The two males are of a very deep crimson colour; the female is of a much lighter shade, more like terra-cotta. This species comes between C. rugipes and C. rugatvs. The carapace is broader than that of C. rugipes, but less broad than that of C. rugatus; there is a transverse groove behind the epigastric lobes as in the latter, but the protogastric groove, as in the former, is not prolonged backwards to meet the branchio-hepatic.
