COPEPODS GATHERED BY ALBATROSS—-WILSON AT 
PAREUCHAETA BRADYI (With) 
Euchaete bradyi WiTH, Danish Ingolf-Expedition, vol. 3, pt. 4, p. 182, figs. 
53a-b, pl. 6, fig. 9a, 1915. 
Stations 4724; 5120; 5231. Established by With upon a single 
female from the northern Atlantic north of the British Islands and 
recorded by Sars in the Monaco plankton, the locality unknown. All 
the Albatross specimens came from the tropical Pacific and are the 
first record from that ocean. It is evidently a rare species and not 
at all well distributed, and the male still remains unknown. 
PAREUCHAETA CALIFORNICA (Esterly) 
PLATE 26, F1curES 384-389 
Euchaeta californica ESTERLY, Univ. California Publ. Zool., vol. 3, No. 5, p. 60, 
pl. 9, fig. 11; pl. 10, figs. 26, 34, 1906. 
Stations 4588; 4700. Established in 1906 by Esterly upon a 
single female taken off the coast of southern California. Scott re- 
corded 10 females in the Siboga plankton from the tropical Pacific, 
Sewell found it in the Indian Ocean (1929, p. 158) but it does not 
appear in the other lists. Neither Esterly nor Scott gave more than 
a brief description, and both left the male unknown. About 40 
specimens, including both sexes, were obtained from these two Alba- 
tross stations and are here described, the male for the first time. 
This male and a female have been given U.S.N.M. No. 74127. 
Female.—Metasome elongate elliptical, two and a half times as 
long as wide; head separated from the first segment and broadly 
rounded in front with a central projection over the base of the rostrum. 
Fourth and fifth segments fused and narrowly rounded posteriorly, 
with a tuft of coarse hairs at the tip of the curve. Urosome two- 
fifths as long and a fourth as wide as the metasome and 4-segmented. 
Genital segment barrel-shaped in dorsal view, considerably enlarged 
through the center with a large ventral protuberance nearer the for- 
ward end. On each side of the genital opening is a fingerlike process 
starting at the anterior margin and extending backward into plain 
view behind the ventral protuberance. The one on the left is a little 
longer than the one on the right, and the two are inclined somewhat 
toward each other. The first two abdominal segments are the same 
length, each a little shorter than the genital segment. The anal seg- 
ment is much shorter and incised at the center of its posterior margin. 
The caudal rami are well separated, a little longer than wide, with 
the outer seta at the center of the outer margin. 
The first antennae reach the center of the first abdominal segment 
and are rather slender, with three or four long setae on the basal half 
and three at the very tip. There are also small cylindrical aesthetasks
