COPEPODS GATHERED BY ALBATROSS—WILSON 215 
appendicular setae on the caudal rami are longer than the plumose 
setae. Total length 3 to 3.75 mm. Metasome 2.28 mm. long. 
Male.—Metasome like that of the female but narrowed more an- 
teriorly and with the posterior corners more angular, extending back 
beyond the center of the genital segment. The rostrum extends al- 
most horizontally forward with a well-defined notch above its base. 
Urosome two-fifths as long and only a fourth as wide as the metasome, 
and 5-segmented. The first four segments are about the same length 
and width, the fifth or anal segment is as wide but much shorter. 
The caudal rami are widely separated, divergent, and wider than 
long, each with one appendicular and five plumose setae. 
The first antennae do not quite reach the posterior corners of the 
metasome; they are rather slender, and neither of them is geniculate. 
The second antennae, mouth parts, and first four pairs of legs are like 
those of the female. The fifth legs are shown in figure 324. The two 
basipod segments of the right leg are considerably swollen; the endo- 
pod is shaped like a ladle and is about as long as the proximal seg- 
ment of the exopod. The bowl of the ladle is concave toward the 
exopod and fits around the inner side of the latter. The proximal 
segment of the exopod is swollen through the center and tapers toward 
each end. The terminal segment is an elongated slender spine enlarged 
at its base and acuminate at the tip. The two basipod segments of the 
left leg are about twice as long as those of the right leg; there is no 
endopod, and the exopod is 3-segmented. The proximal segment is 
narrow at its base and enlarges distally; the second segment is as 
wide as long, with a spine at the inner distal corner and at the center 
of the distal margin a slender process with a flattened spatulate tip. 
The third segment is half as wide as the second, hollowed on its inner 
surface, and enlarged at the distal end into a knob with two inner 
spines and a much longer terminal stylet. Total length 3.27 mm. 
Metasome 2.50 mm. long. 
Allotype male—uU.S.N.M. No. 74114; station 5185, latitude 
10°05’45’’ N., longitude 122°18’30’’ E., between Panay and Negros, 
Philippine Islands. 
Remarks.—The asymmetry of the left side of the genital segment 
and of the ventral protuberance in the female and the ladle-shaped 
endopod of the right leg in the male are the chief characteristics 
of this species.
