GILLS. That of gnathopod 2 is S-shaped 
and directed across sideplate rather than sus- 
pended pendulously; those of Pr. 1 and 2 are 
simple, pendulous, as long as basos; that of 
Pr. 3 somewhat S-shaped; that of Pr. 4 large, 
goose-necked, with cleft tip. 
epimeral plates. Small setae on posterior 
margins; 1st with ventral angle obtuse, hind 
margin slightly convex; 2nd and 3rd with 
straight posterior margins, posterodistally 
right-angled. 
pleopods. First and Second: Biramous, pe- 
duncle and rami subequal, outer ramus of 8 
distinct segments, inner of 9, each with pair 
of long plumose setae; peduncle outer margin 
with plumose setae also; 2 coupling spines. 
Third pleopod a vestigial triangular stump. 
uropods. First: Peduncle longer than rami, 
2 or 3 spines dorsally, a long simple spine 
between rami; inner ramus with 4 spines 
dorsally; 1 long, 2 medium and 2 short end 
spines; outer ramus with 2 long and 2 short 
end spines, none dorsally. Second: Rami as 
long as peduncle which has 3 dorsal spines; 
inner ramus has 2 dorsal spines, 2 long and 3 
short end spines; outer has a short and 2 long 
end spines, none dorsally. Third: Ramus much 
smaller than 1-spined peduncle, 1 long and
