surface, posterior margin rather strongly convex, distal margin straight 

 and at right angles to anterior margin ; hand subrectangular with 

 5 or 6 fascicles of setae on posterior margin and 3 or 4 on anterior 

 which is more convex than posterior ; palm short, oblique, armed 

 at prehensile angle with 3 or 4 spine teeth, finely serrate and armed 

 with many submarginal setae ; finger of usual form with a few 

 setules on inner concave margin. 



Second gnathopods very large in the male, with small epimeron 

 which is ^/s as long as high, lower margin convex and armed with 

 man)' short submarginal setae and slender spines ; second and third 

 joints very similar to the respective joints of the first gnathopod 

 but larger and stouter; fourth joint relatively short with posterior 

 margin twice as long as anterior ; wrist triangular, not as long as 

 broad, with a considerable process on posterior margin which fits 

 into the concave apical margin of preceding joint and is armed with 

 many long, slender setae ; hand very large, rectangular, about twice 

 as long as wide ; posterior margin, which continues by a regular 

 curve into the palm, armed with many long setae ; anterior margin 

 with many fascicles of setae including one at apex ; palm oblique 

 and hollowed to form concavity like shallow bowl which is bordered 

 with many slender setae, and into which fits the finger which is 

 strongly curved and stout. 



In female, first gnathopods very similar in form and size to those 

 of male, but somewhat more slender ; fourth joint shorter than in 

 male and wrist relatively shorter and broader with posterior margin 

 armed with many long pectinate setae, hand and finger similar to 

 male. 



Second gnathopods quite similar to first but larger; wrist armed 

 with many setae on posterior margin which is more angular than 

 in the first gnathopod ; hand oval, twice as long as broad, armed 

 with numerous long setae and short spine teeth; 3 or 4 longer spine 

 teeth at angle between palm and posterior margin; finger moder- 

 ately long and slender with a single seta on convex margin. 



Pereiopods of usual form, terminating in curved dactyls ; epimera 

 of moderate size increasing to fourth ; second joints of last 3 perei- 

 opods normally dilated ; posterior limbs stout and seventh as long 

 as sixth. 



Uropods biramous ; third extending be3-ond others and rami ex- 

 panded into subequal plates armed with many setae on apex, outer 

 plate with outer margin also provided with setae. 



Telson rectangular, not longer than broad, cleft nearly to base, 

 the 2 halves widely dehiscent, each armed with 2 setae at apex
