COPEPODS GATHERED BY ALBATROSS—WILSON 341 
Albatross specimens came from a little farther north in the Philip- 
pines and included females only. This sex can be identified by the 
peculiar structure of the long subapical seta on the fifth legs as shown 
in figure 547. This seta is somewhat flattened dorsoventrally and di- 
vided at its tip, one branch being fringed with hairs while the other 
is smooth. [Sewell finds that the V-shaped appearance of the end 
of this spine is due to viewing the enlarged spinules of the distal 
portion in profile—M. S. W. ]

18, figs. 42-48 ; pl. 36, fig. 49, 1892. 
Stations 53; 76; 8799; 4663. Identified by Sars from three Monaco 
stations and appearing otherwise only in the Carnegie plankton. 
Both sexes are described by Sars (1901, p. 22; 1903, p. 157) in the 
“Crustacea of Norway.”

Spinocalanus magnus WOLFENDEN, Journ. Mar. Biol. Assoc. United Kingdom, 
new ser., vol. 7, No. 1, p. 118, 1904. 
Station 5226. Established by Wolfenden upon specimens obtained 
in the northern Atlantic; described and figured by Sars in the Monaco 
plankton and appearing in the Carnegie list. 
Genus STEPHOS T. Scott, 1892 
STEPHOS PERPLEXUS, new species 
PLATE 36, Figures 548-550 
Stations 27; 5319. Each of these stations yielded a single male. 
The males have exceptionally complicated fifth legs which have a 
general resemblance to those of the preceding genus. 
Male.—Metasome elliptical, the length two and two-thirds times 
the width; head fused with the first segment, narrowed and rounded 
in front and widest at its posterior margin. Fifth segment with 
sharp posterior corners turned inward but without spines. Urosome 
one-fourth as wide and one-third as long as the metasome and 5-seg- 
mented, the segments all the same width and nearly the same length. 
Caudal rami widely separated at the corners of the anal segment, 
divergent, and as wide as long. 
First antennae reach the anal segment, are rather slender, and 
neither of them is geniculate. The exopod of the second antenna is 
longer than the endopod, and its end segment is longer than the sec-
