der at the proximal ends, touching each other in advance 

 of the rostrum. 



The antenna has a long, narrow scale, truncate at 

 the end, the sides are nearly parallel, reaching a little be- 

 yond the antennular peduncle, the external rigid border ends 

 in a small distal spine which scarcely extends beyond the 

 lamellar portion, the fringe is very long. The peduncle 

 reaches about three-fourths the length of the scale. The 

 flagellum is longer than the animal. 



The third maxillipeds are very robust, extending for- 

 ward beyond the upper flao^ellum of the antennule : of the 

 three joints the first is flattened on the inner side, and its 

 proximal end is narrowed, it is much longer than the two 

 succeeding joints taken together, the second and third joints 

 are subequal in length, slightly setose ; the third, which is 

 directed outwards, quickly tapers to a strong, slightly-curved 

 terminal tooth, the inner side bears some strong spines, as 

 also does the distal end of the second joint on the same side. 

 The exopod is small. 



The first pair of legs has the chelate one on the right 

 side, it is short and robust ; the merus is nearly as long 

 as the carpus and propodus together, the propodus tapers 

 somewhat from the proximal end, the fingers are shorter than 

 the palm, curved, and end in simple sharp claws, which cross 

 each other. In the opposite limb, which is slis^htly setose, 

 the propodus tapers considerably to a simple, narrow, curv- 

 ed, and sharp dactylus. 



The second legs are slender and nearly equal to each 

 other : that on the left has the ischium compressed, long, 

 and apparently divided about the middle, with a slight ex- 

 pansion near the proximal end, tipped with a few recurved 

 setae. The merus has .5-7 obscure annuli, it is subequal in 

 lengfth with the ischium. The carpus is about one and a 

 half times as long as the merus, multi-jointed, the joints 

 short and nearly equal in length, except the last, and ex- 

 panding slightly towards the distal end : the propodus is 

 short, the palm being about as long as the last carpal joint, 

 the fingers are about as long as the palm. 



The ambulatory legs are long and moderately robust, 

 the carpal joints are as long and sometimes longer than 

 the meri, and longer than the propodi, except, perhaps, in 

 the last pair, the propodi are slightly compressed and fur- 

 nished with minute hairs behind, the dactyli are short and 

 only slightly curved, simple, and bear two fascicles of 

 minute hairs near the ends. Of these leg^s the first pair have 

 two spines on the outer side of the ischium and three on 

 the merus. The second has one spine on the ischium and
