(Gray, 1831)
The gastric region is fairly well demarcated and subdivided into three areas, the two antero-lateral of which have the surface broken up into low granular convexities: the lateral regions of the carapace are also rugose, the wrinkles being granular and falling into two broken series almost parallel with the curve of the antero-lateral borders. Every margin of the carapace is granular, as is also – besides the rugosities already mentioned – but more finely, a good deal of the surface near the margins. The antero-lateral border is thin and rather sharp and is cut into four teeth, the first three of which are broad and anteriorly acuminate, the last narrow and carinated. The front, which is nearly a fourth the greatest breadth of the carapace, is prominent, is separated from the orbit by a deep notch, and is bilobed, each lobe being cut into three teeth. The inner lower angle of the orbit is of the same size and form and as prominent as the innermost (largest) lobule of the frontal lobes. P1 massive, a little unequal; upper and outer surfaces of carpus and upper (and sometimes in the case of the smaller cheliped the greater part of the outer) surface of hand granular; fingers stout and rather short; inner angle of carpus sharply prominent, somewhat upcurved, a finely beaded line passing from its summit, backwards, along the whole length of the wrist. P2-5 stout, with a rough and furred or scurfy surface, the upper border of the last four joints and the lower border of P4-5 rather abundantly fringed with fine stiff setae. (Alcock, 1898: 179)
