COPEPODS GATHERED BY ALBATROSS—WILSON PARAS 
Female (Sars’ description).—Metasome oblong, about equally nar- 
rowed at each end. Head fused with the first segment and obtusely 
rounded in front with no trace of a crest. Fifth segment entirely 
fused with the fourth, the posterior corners narrowly rounded in 
lateral view. Urosome about a fourth as long and wide as the meta- 
some and 4-segmented; genital segment as wide as long and longer 
than the first two abdominal segments combined; caudal rami as 
wide as long and well separated. First antennae reaching the anal 
segment; second antennae and mouth parts like those of frontalis. 
Fifth legs also similar, but the first two segments are fringed with 
hairs and the end segment is shorter. 
Male.—Metasome elongate-elliptical, nearly three times as long as 
wide and narrowed but little at the ends. Head fused with the first 
segment, the two more than half the entire length; frontal margin 
broadly rounded with no trace of a crest. Fourth and fifth segments 
completely fused, the posterior corners narrowly rounded in side view. 
Urosome one-third as long and one-fourth as wide as the metasome 
and 5-segmented, the basal and anal segments quite short, the three 
middle segments much longer and of equal length. Caudal rami sub- 
circular in dorsal view and well separated. 
First antennae reaching the caudal rami; exopod of the second an- 
tennae considerably longer than the endopod. Mouth parts and first 
four pairs of legs like those of the female; fifth legs somewhat re- 
sembling those of frontalis but differing in details. The endopod of 
the right leg is wider at the base and more acuminate at the tip and 
reaches the center of the second segment of the exopod. The first 
and second segments of the exopod are enlarged a little at their distal 
ends and the third segment is curved and laminate. In the left 
leg the basipods are elongated, the endopod is rudimentary and 1- 
segmented while the exopod is 2-segmented and hooked at its tip. 
Total length 5.75 to 6 mm. 
Allotype male—U.S.N.M. No. 74122; station 5451, latitude 
13°22’99’’ N., longitude 124°00’48”’ E., off Bataan, Philippine Islands. 
Remarks.—Although there were no females with these males, the 
latter possess so many of the characteristics of the humilifrons fe- 
males as to leave no doubt that they are the other sex of the species. 
A single specimen was reported in the Carnegie plankton.
