COPEPODS GATHERED BY ALBATROSS—WILSON 339 
The terminal spine is short, curved and clawlike; the subterminal 
spine is stout, twice as long as the entire leg with a single row of 
rather coarse spines and not divided at the tip. Total length 4.50 mm. 
Metasome 3.40 mm. long. 
Male.—Metasome elongate-elliptical, evenly contracted at each end; 
head fused with first segment and the two together five-eighths of the 
length of the metasome, with a prominent frontal crest. Fourth and 
fifth segments more or less fused, with angularly pointed posterior 
corners. Urosome a little more than a third as long and a little less 
than a third as wide as the metasome, and made up of five segments. 
The first four segments are about equal in length but the anal segment 
is only one-fifth as long. The caudal rami are as wide as long, well 
separated and nearly parallel. 
The first antennae reach the anal segment; the second antennae, 
mouth parts, and first four pairs of legs are like those of the female, 
the fifth legs are distinctive. The right leg is longer than the left, 
the second basipod is swollen to twice the diameter of the first and is 
nearly a sphere. The endopod is 2-segmented, the second segment 
sickle-shaped and with a distinct tooth near the center of the outer 
margin. The exopod is 2-segmented, the basal segment with an angu- 
lar process at the inner distal corner. The terminal segment is sickle- 
shaped, swollen at the end and tipped with a curved spine. The two 
basipods of the left leg reach the center of the basal exopod segment 
of the right leg. The endopod is laminate, 1-segmented, tongue- 
shaped, and just reaches the tip of the basal exopod segment. The 
exopod is 2-segmented, the segments about equal in length, the end 
segment tipped with two long curved filaments and a bunch of shorter 
ones on the inner distal margin. Total length 4.75 mm. Metasome 
5.17 mm. long. 
Allotype female—U.S.N.M. No. 74156; station 5231, latitude 
10°01’15’’ N., longitude 124°43’15’’ E., between Bohol and Leyte, 
Philippine Islands. 
Remarks.—The discovery of the female of this species verifies 
Scott’s separation of the male as a new species and proves that it can- 
not be made a synonym of the species persecans as advocated by 
Farran. [See Sewell (1929, p. 183) for discussion of the synonymy of 
this species. If he is right in considering S. thorti With, 1915, as a 
synonym of S. helenae, then the female has been described by With. 
Further study of these Albatross specimens may be necessary to clear 
up this point.—M. S. W.]
