COPEPODS GATHERED BY ALBATROSS—-WILSON aay 
dorsal surface. The fifth segment is more fully separated from the 
fourth, and its posterior corners are smoothly rounded, with a small 
curved spine nearer the ventral surface. The urosome is relatively 
longer and thicker dorsoventrally, and the caudal rami being on a level 
with the ventral surface are depressed far below the dorsal surface. 
The first antennae reach the second abdominal segment, and neither 
of them is geniculate. The second antennae, mouth parts, and first 
four pairs of legs are like those of the female, while the fifth legs are 
peculiar to the genus. In the right leg the second basipod is swollen, 
the endopod is 1-segmented and nearly reaches the tip of the exopod, 
and the latter is 2-segmented, the first segment one-half longer than 
the second. The end segment is swollen distally into three lobules, is 
flattened on the inner surface, and is tipped with a small spine. The 
left leg is about the same length as the right, the second basipod twice 
the length of the first, and the two combined almost reach the distal 
end of the first segment of the right exopod. The left exopod is 2- 
segmented, the second segment longer than the first, swollen at its tip 
and armed with two or three spines. The left endopod is 1-segmented 
and almost as long as the exopod, the tip curved over and pressed into 
the shape of the bowl of a ladle. Since there was but the single male 
the fifth legs were left intact, and the right one was drawn from the 
right side and the left one from the left side. The figure of the left 
leg therefore needs to be turned over to get it in correct position with 
reference to the right leg. Total length 4.25 mm. Metasome 3.60 
mm. long, 1.53 mm. wide. 
Types.—U.S.N.M. No. 74155; station 5321, latitude 20°19’30” N., 
longitude 121°51’15’”’ E., China Sea off Hong Kong. 
Remarks.—The female can be identified easily by the spine on the 
genital segment, whence the specific name; the details of the fifth legs 
best characterize the male.

pt. 1, p. 106, pl. 24, figs. 1-9; pl. 29, figs. 11-18, 1809. 
Station 5231. Established by Scott in the S¢boga plankton upon 
53 specimens, including both sexes, from the western tropical Pacific 
and reported by Sewell (1913, p. 354; 1929, p. 183) from the Indian 
Ocean. Three males and two females were found in the plankton of 
this Albatross station in the Philippines. The fifth legs of the male 
seen in figure 537 leave no doubt of the identity of the species. In
