Front of carapace sinuate, not at all produced on the 

 median line, but with the angular projection at the sides 

 fairly pronounced. Tufts of hair on the back and sides of the 

 carapace. 



Ocular peduncles subequal with width of the front of the 

 carapace, slender, hardly dilated above ; basal scales slightly 

 developed, produced on the inner side into a spine furnished 

 with hairs on both margins. 



Antennules having the peduncle slightly exceeding the 

 eye-stalks. 



Antennae with peduncle scarcely reaching the apex of the 

 eye-stalk ; basal joint short, with a very small spine on the 

 inner side, and produced on the outer side into a hairy spine, 

 which is almost as long as the penultimate joint of the 

 peduncle ; acicle rather shorter than ocular peduncle, and 

 with tufts of hair on the inner margin ; flagellum not reach- 

 ing to end of the right chelipede, with the joints coloured red 

 and white in alternate series of two or three up to seven. 



Chelipedes very unequal. 



Eight chelipede having the meros compressed, its upper 

 distal margin ending in a spine and a few fringing hairs, the 

 outer side nearly smooth, and having a few spines and hairs 

 on the lower margin ; carpos widening distally, its inner face 

 beai-ing a few hairs, its outer covered with thick tufts of hairs ; 

 the upper edge is sharply defined by seven or eight strong 

 spines, while numerous shorter ones are mingled with the 

 hairs on the upper half of the outer face of the joint ; the 

 propodos is much broader than the carpos, and is covered 

 with a thick felt of hairs, which are produced like fringes on 

 the margins ; among these hairs there are placed about six 

 rows of tubercles (counting the margins), of which the 

 second forms a ridge which continues along the outer side 

 of the dactylos, and the fourth also forms a similar ridge along 

 the immobile finger (these tubercles are usually pink or violet 

 in colour, are rounded above, and stand on a contracted 

 pedicel) ; the inner face of the propodos is nearly quite 

 smooth, the inner (opposed) faces of the fingers are strongly 

 toothed. 



The left chelipede has a somewhat similar meros, also 

 with a single spine on its upper distal margin ; the carpos 

 has two rows of spines on its upper surface, with numerous 

 tufts of hairs, which become very dense towards the distal 

 end; the propodos is much compressed, oval in form, thickly 

 covered with a felt of hairs forming a dense fringe on its
