less than their shorter diameter, Side-plates 1—4 increasing in depth, 
4 largest, much deeper than 5. Postero-inferior angle of 3rd pleon 
segment quadrate, scarcely produced. 
Telson entire, subrectangular, distal margin straight, 2-3 minute 
setules at the rounded postero-lateral angles. 
First antenna, Ist jomt stout, 2nd and 3rd subequal, flagellum in 
¢& 7-,in 2 6-jointed. 
Second antenna subequal to Ist, ultimate joint a trifle longer than 
penultimate. Flagellum in ¢ 7-, in 2 6-jointed. 
Upper lip, distal margin evenly rounded. 
Mandibles, cutting-edge 4—5-dentate, secondary cutting-edge 3—4- 
dentate. 
First maxilla, outer plate with 9-10 spines, slightly notched on 
outer margin where palp should be, but no trace of a palp, inner plate 
with 2 plumose setae. 
Maxilliped, the 2 outermost teeth on apex of inner plate large, 
4th joint of palp small, conical, ending in a long seta. 
First and second gnathopods similar to one another and alike in 
both sexes, 2nd and 3rd joints not in the least expanded, 5th distally 
fringed with 6-8 setae, 6th nearly twice as long as broad, inferior 
margin slightly concave, palm transverse, convex, setulose, defining 
angle rounded. 
First and second peraeopods, inferior margins of 5th and 6th joints 
with 4 and 5 spinules respectively, 6th with 1 apical spine in addition, 
7th without constriction, tubercle or setule. 
Third and fourth peraeopods, 2nd joint oval, hind margin with very 
faint serrations, anterior margin of 6th with 5 pairs of spinules and 
1 apical one, hind margin smooth. 
Fifth paraeopod, 2nd joint very strongly expanded, as broad as long, 
hind margin serrulate, 6th as in 5rd and 4th peraeopods. 
None of the peraeopods are strongly spinose, but all are rather 
stout, Ist, 2nd, 4th and 5th are subequal and longer than 3rd. 
First and second uropods, rami shorter than peduncle, with apical 
spines only, except the inner ramus of 2nd, which has 1 marginal 
spine, . 
Third uropod, short, ovate, 1-jointed, with 1 apical seta.
