numerous setae on apex, and several small setae on inner margin. 

 Maxillipeds with 4-jointed palp, the fourth joint of which is conical 

 and provided with a fascicle of fine setae on apex ; third joint very 

 broad, narrower at base than at apex, with many long setae near 

 distal margin; second joint about as long as third, with rounded 

 process on distal end of inner margin which is provided with setae ; 

 first joint short, with outer margin much longer than inner; outer 

 plate reaching nearly to distal end of second joint of palp, provided 

 with setae on rounded apex and inner margin; inner plate long 

 and narrow, with fine setae on outer and inner margins and several 

 toothlike spines on apex. 



In male, first gnathopods smaller than second, with epimeron 

 elongated anteriorly and having ventral margin only slightly convex 

 and provided with many submarginal setae ; second joint projecting 

 half its length beyond epimeron, constricted proximally, provided 

 with 2 stout curved spines on posterior margin ; third joint as broad 

 as long ; fourth joint about twice as long as wide, articulating with 

 wrist by anterior margin ; wrist triangular, having rounded lobe on 

 posterior side which is provided with many setae ; hand subrect- 

 angular, not so broad as wrist and having palm slightly oblique, 

 provided with diagonal row of plumose spines across surface and 

 with group of setae -\-i distance to distal end of posterior margin, 

 palm provided with many submarginal setae of various lengths and 

 with prehensile spine ; finger strong, curved, and provided with a 

 few setae on inner margin. 



Second gnathopods with epimeron rounded ventrally, higher than 

 long and bearing triangular lobe on posterior margin and submarginal 

 setae ventrall}' ; second joint extending considerably be3-ond epimeron, 

 with roimded lobe at antero-distal angle ; third and fourth segments 

 essentially as in first gnathopod ; wrist triangular and smaller than 

 in first ; hand large, oval, about twice as long as broad, posterior 

 margin continuous with palm by even curve and provided with 

 many teeth and setae of various lengths, prehensile spine present ; 

 finger strong and curved, having a few setae on concave margin. 



Pereiopods furnished with dactyls, last 2 pairs subequal ; epimera 

 moderate with margins entire except for rounded notch on first 3 ; 

 that of second pereipod largest of series. 



Uropods, 3 pairs ; first and second biramous, first longer than 

 second and third, wnth rami somewhat shorter than peduncle, the 

 inner one of which is slightly longer than the outer, provided with 

 2 or 3 spines on dorsal margin and several on apex ; second with 

 peduncle relatively shorter than that of first, otherwise of similar
