setae and strongly convex to form rounded lol^e which extends as 

 far as posterior margin of fourth joint, anterior margin slightly 

 convex and provided with large number of very long plumose 

 spines; hand oval, not much longer than broad, wider than wrist, 

 anterior margin with very large number of long plumose spines, 

 posterior margin with several fascicles of setae, both margins rather 

 convex, palm oblique, marked off from posterior margin by slight 

 triangular process, provided with setae of various lengths; finger 

 short and stout. 



In female first gnathopods with epimeron having anterior ventral 

 corner rounded and projecting considerably so that ventral margin 

 is nearly twice as long as dorsal, provided with long setae ; second 

 joint moderatel}^ long and slender, with setae on posterior margin 

 and rounded lobe at distal end of anterior margin ; third joint longer 

 than broad ; fourth joint broader distally than proximally, with pos- 

 terior margin much longer than anterior and provided with nu- 

 merous setae ; wrist somewhat triangular, twice as long as broad, 

 articulating with oblique distal margin of fourth, anterior margin 

 much longer than posterior so that distal margin is transverse, pos- 

 terior margin provided with numerous long setae ; hand scarcely as 

 long as wrist and about as broad, oval, posterior margin short, palm 

 very oblique, separated from posterior margin by prehensile spine, 

 anterior and posterior margins provided with numerous fascicles of 

 setae, palm provided with numerous submarginal setae of various 

 lengths; finger moderately strong wnth inner margin only slightly 

 concave and serrated. 



Second gnathopods with rectangular epimeron higher than long, 

 with rounded ventral margin provided with long setae ; second joint 

 similar to that of first gnathopod ; third short ; fourth rectangular 

 twice as long as wide, with posterior margin longer than anterior 

 and provided with several fascicles of setae ; wrist triangular, broader 

 than long and with posterior margin produced to form rounded lobe 

 which is densely covered with setae ; hand longer than broad with 

 distal end broader than proximal, palm slightly oblique, jjrovided 

 with numerous submarginal setae, separated from posterior margin 

 by slight process and prehensile spine, anterior and posterior mar- 

 gins provided with numerous fascicles of setae ; finger of usual form 

 and size. In both sexes second gnathopods larger than first. 



Epimera increasing slightly in height to fifth, all provided with 

 setae on ventral rounded margins. 



Uropods biramous ; first and second pairs Avith inner ramus slightly 

 longer than outer, second pair projecting hardly as far as first ; rami
