plate produced into a rounded anterior lobe and in the 

 peraeopoda, etc., it agrees well with his figures, but the first 

 antennae seem shorter in proportion to the second. In the 

 "Endeavour" specimen these (Fig. 5 6) have the general 

 characters found in males of similar genera and have the 

 flagellum elongated to about one-half the length of the 

 body. The eye is large and oval. The first gnathopod is 

 similar to the figure given by Stebbing, but is considerably 

 longer and more slender ; the second gnathopod is also long 

 and slender, agreeing well with Stebbing 's figure and 

 description. Stebbing 's specimen, which was a female, was 

 obtained in the South Pacific near the Kermadec Islands 

 at a depth of 1,140 metres. 



In the first antenna (Fig. 5 a) the first joint of the 

 flagellum is very long and bears on the under side numerous 

 short transverse rows of fine setae, the joints of the flagellum 

 bear calceoli and are twenty-three in number, while the 

 accessory flagellum contains nine, of which the first is the 

 longest. The last joint of the second antenna is longer than
