4 C. BOVALLIUS. NEW ISOPODA. II. 
The wurus is broadly tongue-shaped, with the margins 
rounded, serrated; pointed at the end; on the upper side it 
is distinetly keeled. 
The inner ramus of the uropoda is sligthly emarginated 
at the exterior margin. 
In habitus Aega Lovéni comes nearest to Aega ven- 
trosa, SCHIOEDTE et MEINERT (non M. SARS), but is distinguished 
by the length of the fourth pereional segment, the longer 
second pair of antenne&e, the first pleonal segment and the 
length of the posterior pairs of pereiopoda. 
Adult male. 
(Ela Tält 0) 
The front margin of the head is evenly rounded, the 
hind margin is almost straight; the fourth pereional segment 
is more than twice broader than the head (29:13). 
The eyes are oblong, a little broader at the posterior 
end, the ocelli are arranged in 7 rows. 
The first pair of antenne (P1. I, fig. 3) reach over the 
head and the first pereional segment. The first joint of the 
peduncle is broad and stout, twice as long as the second, the 
third is slender, linear, as long as the two preceding together. 
The flagellum is scarcely longer than the peduncle (20:19), 
composed of 17 articuli, the basal one is the longest, the 
last ten articles carry short hairs. 
The second pair of antenne (P1. I, fig. 3) are nearly twice 
as long as the first pair (13:7), the basal joint of the pe- 
duncle is very short, the second longer, the third short, 
the fourth and fifth much longer, equal; the two last ones 
carry bundles of fine hairs. The flagellum is longer than 
the peduncle, it consists of 18 articles, all carrying short 
fine hairs. 
The first segment of the pereion is longer than the head, 
and equal to the second, the third is a little longer, the fourth 
is the longest, the fifth, scarcely shorter than the fourth, the 
sixth and seventh decreasing, the seventh still longer than 
the first. The fifth segment is the broadest.
