joints subequal, 3rd 4 length of 2nd, flagellum more than twice as 
long as peduncle, 48-76 jointed, accessory flagellum 6-8-jointed. 
Second antenna about half length of Ist, lst joint stout, as lone 
as: 3rd, 2nd half as long as broad, gland-cone scarely reaching 1 
length of 3rd, 4th and 5th subequal, flagellum shorter than peduncle, 
20-30 jointed. 
The duct opens at the apex of the gland-cone, but through a small 
subapical conical papilla on the lower surface. 
Upper and lower lips normal. 
Mandibles, cutting-edge 4-dentate, secondary cutting-edge in left 
lamellar, 4-dentate, in right tubercular with 4-5 prongs, some of them 
denticulate, spine-row in left with 10, in right with 4 spines, 2nd joint 
of palp thrice Ist, 3rd a trifle longer than 2nd. 
First maxilla, inner plate with 8-10 feebly plumose setae, outer 
with 9 serrate spines, 2nd joint of palp in left with 10 + 4 slender 
apical spines, in right with 6 teeth and 1 stout and 1 slender spine on 
outer apical angle. 
Second maxilla normal. 
Maxilliped, inner plate with 3 apical spines and several setae, inner 
margin of outer plate with blunt spines passing distally into longer 
and plumose setae, apex reaching almost half way along 2nd joint of 
palp, 38rd joint of palp half 2nd, 4th 3 3rd and much more slender, 
inner margin of 2nd and 3rd thickly fringed with setae. 
First and second gnathopods similar to one another, but 2nd rather 
larger, 5th joint triangular, 6th oval-oblong, scarcely broader distally 
than proximally, palm rather oblique, slightly convex, defined by 1-3 
spines in Ist and 5—4 spines in 2nd gnathopod, finger matching palm. 
In ? similar but smaller than in ¢. 
First and second peraeopods slender, 2nd joint a little longer than 
Ath, 6th a little longer than 5th, hind margins of 5th and 6th with 
respectively 4 and 6 groups of spines and setae, hind margin of 7th 
with 4 spine-setae. 
Third to fifth peraepods, 2nd joint oval, anterior margin spinose 
and setose, hind margin gently convex, serrulate and setose, postero- 
inferior angle rounded, reaching to middle of 3rd, 4th a little shorter 
than 6th, 5th equal to 2nd, 6th a little shorter than 5th, anterior 
margin of 5th and 6th spinose, of 7th with 11-138 spine-setae, 4th to 
6th joints densely setose, especially in 5th peraeopod, and more so in 
6 than °. 
Branchial lamellae simple. 
First uropod, peduncle with 6 spines on inner and 9 on outer upper 
margin, rami subequal, a little shorter than peduncle, inner with
