BRACHYCRA. RATHBUN. 117 



denticulated margin which gradually advances to the acute 

 inner angle. Three thick lateral teeth, more produced than 

 the orbital tooth and each tipped with a small spine. No 

 subhepatic projection, only a few granules. Posterior 

 margin broad. 



Chelipeds very unequal, less hairy than carapace, 

 pubescence not concealing roughness, large chela totally 

 bare. Outer surface of merus granulate ; upper edge denti- 

 culate, a large subterminal tooth, a smaller terminal one; 

 inner edge tuberculate, lower edge partly so. Carpus 

 covered with pointed tubercles, sharper and more spinelike 

 on the smaller carpus, which also has a spine instead of a 

 tubercle at the inner angle. Larger palm bare and smooth 

 except for a band of tubercles or large .granules along the 

 proximal end of the outer surface and a patch of the same 

 at the proximal end of the upper surface. Two or three 

 granules at base of dactylus. Fingers light brown, the 

 colour covering the distal two-thirds of the fixed finger and 

 almost the whole of the dactylus. The outer surface of the 

 smaller palm is covered with pointed tubercles arranged in 

 approximately seven rows, and a patch of the same is at 

 the proximal end of the dactylus above. Ambulatory legs 

 hairy, the merus roughened above by fine, unequal spinules. 



Relationships. The very unequal chelae suggest those of 

 P. spinicarpus 12 but in that species the rough area on the 

 larger palm is much greater, also the carapace and legs are 

 longer. The carapace of tantnlus resembles in shape that 

 of P. quadridentatus 13 de Man, which also has a striking 

 inequality in chelae, but differs from tantulits in having five 

 (instead of four) antero-lateral teeth, counting the post- 

 orbital tooth, and in the larger palm being finely granulate 

 outside.
