Stations 3867 ; 3921; 4688; 4685; 5185; 5231. Identified by Sars in 
the Monaco plankton; based on female specimens only which he fully 
described and figured. He claimed that Scott’s Huchaeta wolfendent 
in the Siboga plankton was a synonym of pubera and of necessity 
adopted the wolfendent male as the male of pubera. It will be shown, 
however, under wolfendeni (p. 217) that the two species are not the 
same, and that leaves pubera with females alone. Fortunately, the 
Albatross specimens included males and one of these is here described 
and figured for the first time. 
Female.—Metasome elliptical, 224 times as long as wide, narrowed 
considerably in front but only a little behind, with broadly rounded 
posterior corners. Urosome nearly half as long and a third as wide 
as the metasome and 4-segmented. Genital segment as long as the 
entire abdomen, with a large ventral protuberance, having on the 
right side of the genital area a short lamella terminating in a curved 
point. The first antennae are slender and reach slightly beyond the 
posterior corners of the metasome. Total length 4mm. Metasome 
2.92 mm. long, 1.15 mm. wide. 
Male.—Metasome with the same proportions as in the female but 
more pointed in front, with the posterior corners evenly rounded in 
side view but in dorsal view narrowed to thin edges turned outward. 
Urosome more than half as long and less than a fourth as wide as 
the metasome, 5-segmented, the segments narrowing slightly back- 
ward. The genital segment is shorter than either of the first two 
abdominal segments, which are of equal length and one-half longer 
than the penultimate segment. The anal segment is so short as to be 
scarcely visible and the caudal rami are also very short and 
subglobular. 
The first antennae are longer than in the female and reach the ab- 
domen, 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 large and extend beyond the tips of the caudal 
rami in spite of the length of the urosome. The basipod of the right 
leg is considerably swollen; the exopod is 2-segmented, the distal 
segment tapered into a curved spine. The endopod is also 2-seg- 
mented but no longer than the basal segment of the exopod. In the 
left leg the second basipod is elongate but not swollen and carries on 
its inner margin near the tip the rudiment of an endopod. The inner 
projection of the second segment of the exopod is enlarged and notched 
at its tip, and the outer margin is fringed with spinules. The third 
segment has a rounded protuberance tipped with a spine on its 
inner Margin opposite the tip of the projection of the second segment. 
Between the base of the third segment and this projection are the
