The eyes are distant by a fifth of the breadth of the head, 
they are broader at the posterior end, rounded, straight at the 
frontal end, the ocelli are large, placed in nine rows, 13 in 
the median row. 
The first pair of antenne (P1. II. fig. 13) reach to the 
anterior margin of the first pereional segment. The flagellum 
is composed of 5 to 6 articuli. 
The second pair of antenne (PI. II. fig. 13) reach over 
the anterior margin of the third pereional segment. The 
flagellum consists of 14 articuli carrying very minute hairs. 
The first segment of the pereion is as long as the head, 
the second a little shorter, the third as long as the second, 
the fourth to the sixth subequal, longer, the seventh is the 
shortest of all. 
The epimerals (P1. II. fig. 12) are very narrow, the four 
last ones posteriorly produced into acute points. The epime- 
rals of the second to sixth segments occupy the whole length 
of the segments, the ones of the seventh exceed the segment 
and reach nearly to the posterior point of the first pleonal 
segment. 
The pereiopoda. The three first pairs are short; the fe- 
mur broad with three or four plumose bristles, the genu long, 
without hairs or spines, the tibia stout, with three strong, öl 
tuse -spines along the inner margin and some long bristles at 
the outer, lower corner, the carpus short with a short spine 
at the inner, lower corner, the metacarpus with the inner 
edge produced, carrying four strong, short spines, the dactylus 
longer than the metacarpus, strong (P1. II. fig. 14). The 
four last pairs of pereiopoda increasing in length to the sixth 
pair, the seventh a little shorter than the sixth; the femur is 
oblong' ovate (PIL. II. fig. 15), the genu long, with four fine, 
short spines along the inner margin, and some bristles at the 
lower corners, the three following joints are shorter, subequal, 
armed in the same manner, the dactylus is half as long as” 
the metacarpus. 
The pleon is short, as long as the two preceding seg- 
ments together. The first segment is totally covered by the 
seventh pereional, the three following equal in length and 
breadth, the hinder corners pointed, even as in the first seg- 
ment. The fifth segment is longer than the preceding and 
much narrower.
