Stations 3; 470; 3799; 4700; 4757; 4758; 5120; 5129; 5185; 5223; 
5230; 5246; 5320; 5840. Specimens, including both sexes, were identi- 
fied from station 4700, between Easter Island and the Galdpagos 
Islands, by Sars, who also recorded the species from three stations 
in the Monaco plankton. The Monaco specimens were all from the 
northern Atlantic, so that this is the first record from the Pacific and 
these are the first males ever taken. 
Female.—Metasome elliptical, two and one-third times as long as 
wide; head fused with the first segment, and the fourth with the fifth 
segment, corners rounded. Urosome one-fourth as long and one-sev- 
enth as wide as the metasome, 4-segmented, segments diminishing in 
Jength backward. First antennae not quite reaching the genital seg- 
ment; exopod of second antenna slightly longer than endopod. fifth 
leg laminate ovate, with a tiny spine at the tip and a much larger one 
at the center of the inner margin. Total length 1.60 mm. 
Male.—Fully as large as the female and similar in general form, 
but the urosome is proportionally longer and 5-segmented, the anal 
segment shortened and the penultimate segment lengthened, the other 
three about equal in length. 
The first antennae reach the middle of the urosome and the basal 
segments carry slender aesthetasks in addition to setae. The fifth 
legs are slender and reach beyond the tips of the caudal rami, and their 
structure is very different from those of the other males. ‘The second 
segment of the left basipod is inflated, and the exopod is 2-segmented, 
the second segment curved and tipped with a flanged spine. The first 
segment carries at its outer distal corner a blunt rodlike spine. The 
right leg has two cylindrical basipod segments, which combined almost 
reach the distal end of the first exopod segment of the left leg. The
