First antenna reaching to end of 4th peduncular joint of 2nd 

 antenna, 1st joint stout, 2nd a little longer, flagellum longer than 

 peduncle, 4-jointed, 3rd joint longest, 4th minute. 



Second antenna, 3rd joint without scale, 5th and 6th subequal, 

 longer than first 4 joints together, flagellum nearly twice as long as 

 peduncle, ca. 38-jointed in $ , ca. 24 in $ . 



Upper lip short, as broad as long, apex rounded. 



Lower lip with short, broad lobes, inner apex strongly setose. 



Mandibles, cutting-edge 4-dentate, secondary cutting-edge in left 

 4-dentate, spine-row with 5 spines, molar fairly prominent, palp 

 with 3rd joint shorter than 2nd, with apical seta, no marginal setae 

 on 2nd or 3rd joints. 



First maxilla, outer plate^with ca. 10 (?) spines, inner plate with 

 5 setae. 



Second maxilla, outer and middle plates with 4 spines each. 



Maxilliped, inner plate nearly as long as 2nd joint, 2 coupHng- 

 hooks near base, 4th and 5th joints not expanded, epipod reaching 

 end of 4th joint, narrow lanceolate, outer margin slightly angular, 

 apex acute tapering. 



First peraeopod in $ stout, subchelate, 2nd and 3rd joints sub- 

 equal, inner surface of 3rd joint with 7 transverse rugae on inner 

 margin, 4th joint with 1 stout spine on outer apex, 5th joint tri- 

 angular, distally produced on inner side, with 1 stout spine on 

 inner apical angle and another further along distal margin, 6th joint 

 curved, inner margin distally serrulate, 7th joint half as long as 

 6th, biunguiculate. In 5 prehensile but scarcely stouter than the 

 other paraeopods, 3rd joint without rugae, 5th joint with 1 long 

 spine on inner apical angle, inner margin of 6th joint not serrulate. 



Second to seventh peraeopods similar, the posterior ones longer 

 and rather more slender than anterior ones, 2nd and 3rd joints sub- 

 equal, 4th with 2 spines on outer apex, 5th and 6th subequal and 

 equal to the 2nd and 3rd, inner margin of 6th with 4 spines in $ > 

 3 in $ , 7th joint biunguiculate. 



First pleopod 3 , peduncle narrowing rather rapidly, apex not 

 expanded, but outer angle with 1 spine, ramus rounded truncate* 

 setose. 



First pleopod 5 (operculum) rather pear-shaped, as broad as 

 long, tapering to a broadly rounded apex, with a few scattered 

 setae. 



Second pleopod $ narrow, outer margin nearly straight, apex 

 subacute, setose, ramus at some distance from apex, very small, 

 male stylet stout, reaching to apex.
