the strongest, 4th segment with median carina, which is rounded in 
profile, highest in the middle and stronger in ¢ than in 9, posterior

the 3rd than the 2nd, postero-lateral margins of 4th and 5th segments 
each with a tooth. 
Telson reaching to end of uropods, gradually tapering, apices acute, 
contiguous, cleft not quite as far as centre. 
First antenna to end of peraeon in ¢, to about 4th peraeon seg- 
ment in 2, Ist and 2nd joints subequal, lower apex of Ist ending in 
2 in 2 teeth, both joints in ¢ with 9 bunches of setae on lower 
margin, 3rd joint half length of 2nd, flagellum scarcely as long as 
pendunele, ca. 24-jointed in ¢,8-jointed in 2, accessory flagellum 
extremely minute and indistinct. 
Second antenna longer than first antennae, reaching in ¢ to end of 
5rd pleon segment, in 2? nearly to end of peraeon, ultimate joint 
of peduncle in ga little longer than penultimate, in 2 scarcely as 
long, upper margin of penultimate joint in ¢ with ca. 18 bunches 
of setae, flagellum longer than peduncle, ca. 40-jointed in 3, 16- 
jointed in 9. 
Upper and lower lips normal, but outer lobes of lower lip more 
truncate apically. 
Mandible, cutting-edge straight, entire, with 1 tooth at one end 
and 2 at the other, secondary cutting-edge in left 7-dendate, in right 
very feeble, serrulate, spine-row with 6—7 spines, 3rd joint of palp only 
a trifle shorter than 2nd. 
The other mouth-parts without particular features. 
First and second gnathopods, palm defined by 2 blunt tubercles, 
each surmounted by a spine bearing a cilium near its apex. 
Third to fifth peraeopods, hind margin of 2nd joint entire, that of 
5th peraeopod serrate, posterior apical angle rounded, in the 4th 
peraeopod 6th joint longer than 4th, 5th and 7th subequal, shorter 
than 4th. 
Uropods, peduncle of Ist and 2nd spinose on inner margin, inner 
apex of peduncle of 8rd produced into an acute tooth furnished with 
a spine, outer ramus of each uropod slightly shorter than inner, inner 
margin of inner ramus of Ist and 2nd uropods and both margins of 
both rami of 3rd uropod spinulose.
