obliquely truncated, the outer with 19, the inner with 15 long 

 setae denticulated on their inner edges. Inner fixed lobe rounded 

 at apex, with a number of fine setae, the innermost ones being 

 plumose. Inner margin slightly concave with a thick row of 

 simple setae. 



The Maxillipeds. Epipodite almost rectangular, very slightly 

 longer than broad, the angles rounded, reaching to end of the 

 second joint of exopodite. The basos a little more than twice 

 as long as broad ; ischios very short ; meros produced externally 

 for three-quarters the length of the carpus ; carpus rather sunk in 

 meros with external margin straight and internal margin convex ; 

 propodos ovate longer than broad ; dactylos narrow lanceolate, as 

 long as propodos. Endopodite arises from the basos and reaches 

 to the middle of the carpus, bearing externally long plumose setae 

 and internally 2 coupling spines. 



The First Peraeopod (Gnathopod). In the first as in all the legs 

 the coxos is fused with the epimeron. The basos is twice as long 

 as broad ; ischios two-thirds length of basos and narrower ; meros 

 sub-triangular broader than long, anteriorly produced into a pointed 

 process ; carpus as long as broad, broader than third ; propodos 

 obovate, proxirnally twice as broad as distally, anterior margin 

 evenly rounded, palm not well defined, slightly concave, beset 

 with numerous setae and about 7 spines. These spines are tuber- 

 cular in shape at the distal end, but towards the base of the 

 palm gradually approximate to the ordinary form of setae, and 

 eventually are indistinguishable from the setae fringing the base 

 of the hand. The dactylos is strongly curved at the base, but 

 distally nearly straight ; a minute secondary unguis at base of 

 the terminal one, and behind that some very minute denticula- 

 tions. 



The gnathopod of the female differs hardly at all from that 

 of the male ; the hand is equally developed and of the same 

 form. The spines on the palm, however, are bicuspid and more 

 slender. 



The Second and Third Peraeopods. The basos is twice as long as 

 broad ; ischios two-thirds length of basos and also twice as long 

 as broad ; meros as long as ischios, subtriangular, anterior margin 

 expanded distally ; carpus a little shorter than meros ; propodos 

 as long as ischios ; both the carpus and propodos have strong 

 spines on the posterior margins ; dactylos a little more than half 

 the length of the propodos, with secondary unguis and an apical tuft 

 of setae.
