does not move when taken out of the water, even if it is touched, and a 
good deal of extraneous matter is usually found among the short sete which 
cover the body. 
AMPHIPODA. 
Genus Nicea. 
(Cat. Amphip. Crus. Brit. Mus., p. 51.) 
Nicea egregia, sp. nov. Plate II., fig. 2. 
Female.—Body much compressed dorsally ; each segment of pereion 
raised into a crest which projects backwards over the succeeding segment ; 
first three segments of pleon produced dorsally into crests rather more pro- 
minent than those on the segments of pereion. Crest of first segment of 
pleon extending along the dorsal surface of the cephalon and rising abruptly 
therefrom. Eye moderately large, round. Cephalon produced slightly up- 
wards at the base of the uppér antenna. Upper antenna shorter than the 
lower, peduncle of three joints nearly equal in length, decreasing slightly in 
size distally ; flagellum about as long as the peduncle, each joint bearing 
long auditory cilia on its under side at the distal end. Peduncle of lower 
antenna with three joints visible, last two equal in length and considerably 
longer than the first, flagellum longer than the peduncle, sete in short tufts 
at the end of each joint. First and second gnathopoda equal in size and 
similar in form ; carpus long, sub-triangular, with sete on its inner distal 
angle; propodos oblong not broader than carpus, palm slightly oblique, 
defined by a stout tooth, hairy. Coxw about as deep as their respective 
segments. Pereiopoda subequal rather stout ; meros expanded distally and 
produced anteriorly in the first two, posteriorly in the last three pereiopoda, 
each pereiopod with dactylos long strong and curved with a short seta 
arising on the inner margin towards the end. All the pereiopoda nearly free 
from sete. Of the last three pairs of pleopoda, the first two reach to the 
same point slightly beyond the extremity of the body ; the rami are about 
equal in length to the peduncles, and are provided with short strong teeth 
at the extremity and on their upper margins. Last pair of pleopoda 
apparently rudimentary, consisting of two joints rounded and perfectly free 
from sete. Telson concave below, subrectangular, about as broad as long, 
rounded posteriorly, cleft about half-way down. 
Male.—Differs in having the crests on segments of pereion not so 
prominent; first segment not produced so much along the head ; second 
gnathopod when fully developed chelate, basos long and narrow, ischios and 
meros short, carpus apparently united with propodos, which is large and 
produced distally into a fixed finger against which the dactylos impinges, 
dactylos strong, rather blunt at end ; the ends of both fingers setose. The 
first pair of gnathopoda same as those of female.
