In the second maxillipedes the merus is the longest joint. 

 The propodite is short and inflated ; the dactyl bears a few 

 terminal spines. The exopodite is very long and slender ; its 

 peduncle reaches beyond the distal extremity of the merus, 

 and its flagellum well beyond the tip of the dactyl, when the 

 appendage is straightened out. The epipodite is rather slender. 



The teeth on the crest of the ischium of the third maxillipedes 

 are rather blunt. The merus is slightly shorter than the ischium. 

 None of the joints are armed with large spines. The carpus, 

 propodite, and dactyl are nearly equal in length. The exopodite 

 is short, net reaching the distal end of the merus. 



The chelipeds are massive, are densely setose, and have more 

 or less rounded angles. They are slightly unequal. They are 

 longer in the male than in the female. In the specimens taken 

 by the Helga the chelipeds are -71 of the length of the body 

 in the males, and only -59 in the females. The merus is Very 

 slightly shorter than the propodite, though Norman^ in his 

 original description of the species (1882), says the menis is the 

 longest joint. At its distal end the merus bears two spines, 

 one above and one below. It is thicker distally than at the 

 proximal end. The carpus is short and stout and bears several 

 spines, three on the inner side, one on the outer, and one below. 

 Sometimes, however, only four spines are present. The propodite 

 is the largest joint ; it is quite unarmed and is very thickly 

 covered with hair ; the palm is slightly longer than the fingers, 

 the tips of which cross when closed. The whole surface of the 

 appendage is more or less granular. The setae are thickest on 

 the carpus and propodite. 



The second pair of legs are rather stouter than the next 

 three, which are long and slender. The second and third pairs 

 are chelate, and their coxae bear on the inner side large flattened 

 lobes, which in the third pair end in a conspicuous hook at 

 the outer side. These lobes are almost entirely absent in the 

 female. The fourth legs are the longest ; the fifth are a little 

 ihorter, and the third and second slightly shorter still. 



In the male the first pleopods lie close together, and are pressed 

 against the ventral surface. In adult specimens they reach as 

 far as the base of the second legs. They consist of two joints, 

 the first of which is very short. The second is expanded into 

 a flattened blade, which is concave on the inner side, so that 

 when pressed together the two pleopods form, a tube. On the 

 inner surface of each there are two rows of stiff setae, one on 

 the margin, and the other springing from a low ridge that runs 

 from the proximal into the concave distal part ; the setae all 

 point forwards. 



In the female the first pleopods are very slender and short ; 

 the distal part is muitiarticulate and is fringed with long pinnate 

 hairs. 



in the male the second pair of pleopods has a large appendix 

 w.asiulina attached to the endopodite. It usually lies closely 

 pressed against the first pair. It is nearly as long as the pleopods
