til 



aculeus, which is short, nearly as wide at its proximal as at its 

 distal end, where it merges with the spiniform portion ; the whole 

 aculeus much less than half the length of the vesicle. Chela' with 

 humerus much less coarsely granular above and in front than in 

 C. margaritatus, very finely granular below, smooth behind ; bra- 

 chium with superior granular crest, posterior and inferior surface 

 smooth, anterior surface smooth except for some coarse granules 

 on the inferior crest and on the inferior prominence and two larger 

 granules above ; keels of hand normal in number, very finely 

 granular, the interspace covered with a wide-meshed network of 

 granules ; width almost equal to length of underhand, the inner 

 edge more strongly convex than in ft margaritatus, with much 

 closer, less open concavity where it merges with the immovable 

 finger ; fingers more strongly carved. Pectinal teeth 4. 



Measurements in mm. — Total length 38, carapace 6, tail 24, 

 brachium 4-5, underhand 4-5. movable finger 5*3, width of hand 4- 2.

2 . Colour somewhat as in G. gemmifer, but much paler; the 

 yellow or red predominates so that the integument may be described 

 as red varied with black ; chelae deep red with black keels. Cara- 

 pace and terga with a few coarse pearl-like granules scattered here 

 and there ; anteocular area practically smooth ; relative length of 

 carapace and tail-segments as in G. gemmifer; intercarinal spaces of 

 tail almost smooth, those of the 5th weakly granular ; vesicle as in 

 C. gemmifer. Chelce with humerus weakly granular, except for the 

 upper and anterior crests, which are coarsely so ; brachium almosl 

 wholly smooth except for a few coarse granules on the upper crest 

 and a few in front; intercarinal spaces of baud with a very tineh 

 granular network, almost smooth ; keels very weakly granular ; 

 shape of hand as in G. gemmifer. Pectinal teeth 5. 



d . With tail very long and slender; carapace as long as the 

 1st and half the 2nd segments, much shorter than the 5th. Tail 

 more than six and a half times as long as the carapace, the 1st 

 segment longer than wide, 2nd nearly twice as long as wide, 5th 

 more than four times as long as wide; vesicli | fiL. r . 18, ( '. 1>) very 

 long, as long as the 5th segment of the tail, flat below, about a^ 

 wide as the 4th segment, its height equal to that of the 5th, nearly 

 parallel-sided, very coarsely granular, ending disrallyin a righl and 

 left shoulder-like prominence; base <>f aculeus when seen from 

 above resembling a Large cylindrical tubercle, upon the summit of 

 which is situated the strongly bent spiniform distal extremity; 

 when seen from the side the base of the aculeus merges without 

 constriction with the adjacent end of the vesicle. Chela very much 

 as in female ; humerus, brachium. and underhand all shorter than
