« The first pair of antenne consist of two long joints, angu- 
larly articulated; the end of the last joint is swollen, contai- 
ning a gland, and terminates into a claw-like projection. 
The mouth-organs are of the same structure as in the 
preceding species. 
The segments of the pereion are high,inflated. The first 
and second segments are coalesced into one, not half as long 
as the following segment. A median keel exists here as in 
the preceding species, but the coalesced first and second seg- 
ments and the seventh carry only one dorsal spine, the others 
two each. The keel continues to the porterior margin of the 
last ural segment, with two spines on each of the pleonal seg- 
ments. The posterior margins of the pereional segments are 
bordered with small spine-like tubercles. The last pereional 
segment is as long as the preceding. No trace of epi- 
merals. 
The first pair of pereiopoda are short, not a sixth of the 
length of the third pair. The second pair are twice as long 
as the first. The metacarpi of both pairs are longer than the 
carpal processes. The fifth pair are not fully twice as long as the 
seventh (11:6) and nearly a third longer than the fourth (11:58) 
The lower anterior corner of the femur of the fifth, sixth, and se- 
venth pairs is produced into a sharp point. The tibize, carpi, and 
metacarpi of the third and fourth pairs are bordered with hairs; 
the lower hinder torner of the carpus of the seventh pair 
carries a bundle of longer hairs. The ends of the metacarpi of 
the five last pairs are all swollen, containing glands (see 
WiLLEMOÉFs-SUHM 1. c.). At the bases of the fourth, fifth, and 
sixth. pairs the branchial sacks are fixed. 
The pleon and urus together are longer than the six first 
pereional segments. The first segment of the pleon is much 
the largest, twice as long as the last pereional. The keel on 
the dorsal side of the pleon shows two or three small spines 
on each segment. 
The last segment of the urus is keeled, but without spines. 
The peduncles of the last pair of the uropoda are twice as 
long as the outer ramus; narrower than the length of the same.
