Antenna 1, 1st joint largest, outer margin produced in a large 

 recurved, spiniform process, 2nd and 3rd subequal, fiagellum not 

 quite as long as peduncle, (i-jointed, 1st joint very short, '2nd longest, 

 6th and 7th minute. 



Antenna '2, 2nd joint largest, grooved, 3rd-5th joints gradually 

 increasing in length, flagellum shorter than 5th joint, 3-jointed. 

 Flagella of both antennae sparsely setose. 



Upper lip triangular, apically incised. 



Lower lip, lobes apically tapering, with a small apical projection. 



Mandibles, cutting-edge obscurely crenulate, cutting plate with 

 recurved teeth, molar not very pi'omiuent, palp stout, 1st and 3rd 

 joint subequal, 2nd longer, 3rd apically setose. 



Maxilla 1 6-toothed. 



Maxilliped 4-jointed, 1st not very distinct, 3rd largest, 4th short, 

 rounded, with a few apical setae, epipod short, oval. 



Peraeopod 1 stout, 2nd joint widening rapidly from a narrow base, 

 without distal projection, 5th small, triangular, inferior apex sub- 

 acute, not projecting, 6th large, oblong, scarcely narrowing distally, 

 palm short, slightly concave in distal half, sparsely setose, finger plus 

 unguis longer than palm, overlapping apex of 5th, inner margin finely 

 denticulate. 



Peraeopods 2 and 3 fairly stout, third joint | length of 2nd, 4th 

 distally as wide as long, 5th underridiug 6th, which is equal to 3rd, 

 slightly ovate, inferior margin sparsely setose, with a stout apical 

 spine, finger shorter than 6th. 



Peraeopods 4-7 similar but 5th joint not underridiug 6th, with a 

 spine on inferior apex ; peraeopod 7 not appreciably shorter or more 

 slender than the preceding ones. 



Pleopod 1 large, outer ramus opercular, indurated, outer surface 

 with one median longitudinal groove and another just within the 

 outer margin, the surface between the grooves pitted, distal margin 

 densely fringed with plumose setae, inner ramus thin, scarcely half as 

 wide as outer ramus. 



No stylet showing on pleopod 2. 



Uropod, inner ramus not quite reaching telsonic apex, ventral 

 surface of 1st joint strongly keeled, 2nd shorter than 1st, subtriangular, 

 longer than its basal width, apex rounded, inner margin straight, 

 outer margin straight or slightly concave, densely fringed with 

 plumose setae, outer ramus not meeting its fellow, reaching just 

 beyond apex of 1st joint of inner, ovate, outer distal margin concave, 

 apex acute, whole of outer margin densely fringed with plumose 

 setae.
