COPEPODS GATHERED BY ALBATROSS—WILSON 297 
rower than the genital segment, the first two segments of the same 
length, the third one three-fifths, the anal segment two-fifths as long. 
The caudal rami are twice as long as wide and symmetrical. 
The first antennae are longer than in the female and reach 
the genital segment. The right one is geniculate, and four of its mid- 
dle segments, beginning with the second one behind the hinge, are 
enlarged to twice the diameter of the others and the first two have a 
crest fringed with small teeth on their outer margin. The second 
antennae, mouth parts, and first four pairs of legs are like those of the 
female. The fifth legs are shown in figure 204; each is uniramose and 
4-segmented. The terminal segment of the right leg is transformed 
into a stout spherical chela without spines or processes. The terminal 
segment of the left leg is tipped with a slender, curved claw and a 
stout spine. The second segment of this leg carries at its distal end 
a small spine which might be regarded as the rudiment of an endopod. 
Total length 2.90 mm. Metasome 2.40 mm. long, 0.76 mm. wide. 
Types.—U.8.N.M. No. 70747, off Robben Island, Okhotsk Sea. 
Remarks.—The complicated asymmetry of the urosome in the 
female and the last segment of the metasome in the male are sufficient 
to identify this new species. It appears to be local in its distribution.

briefly described in 8 lines by Brady in his Challenger report from a 
few specimens from the mid-Pacific; again figured and briefly de- 
scribed, 4 lines only, by Giesbrecht in his Naples monograph. Later 
listed from 13 Siboga, 2 Monaco, and 4 Carnegie stations without 
further description or figures. A number of females and males were 
found at these Albatross stations, of which the first 6 were identified 
by Sars, who also made some excellent pencil drawings of them. As 
Brady’s and Giesbrecht’s descriptions and figures, the only ones ever 
published, are not only very inadequate but also misleading in some 
details, Sars’ figures are here reproduced with full descriptions of 
both sexes. 
Female.——Metasome elliptical, four times as long as wide and but 
little narrowed at each end. Head more or less fused with the first 
segment, the lateral hooks small and nearly straight. Dorsal eyes 
well separated, the two rostral lenses with their inner walls in contact 
and swollen into a large sphere. Posterior corners of metasome pro- 
duced into triangular acute spines, the one on the left much larger
