of the female. The second basipod of the right fifth leg is swollen to 
about three times the diameter of the first basipod. The first exopod 
segment has an angular swelling on the outer margin at the center and 
a small knob at the inner distal corner. The second segment has a 
curved process at the base and a smaller straight process near the 
center of the inner margin. The third segment is sickle-shaped, with 
a knob on the convex margin, the point of the sickle overlapping the 
base of the second segment. The right endopod is slender and reaches 
the distal end of the second segment of the exopod. The two basipod 
segments of the left leg are about equal in length and quite slender, 
without knobs or swellings. The left exopod is 3-segmented, the two 
proximal segments equal in length, the end segment much shorter and 
claw-shaped. The left endopod is 1-segmented, nearly as long as the 
exopod, and dentate on its inner margin. Totallength3 mm. 
Allotype female.—U.S.N.M. No. 67242; Fiji Islands. 
Remarks.—In the preceding species the fifth legs of the female con- 
sisted of a short basal segment and a very long and stout spine. In the 
type species joanae, described by Scott in the Siboga plankton, the 
fifth leg of the female consisted of a short basal segment tipped with 
two still shorter spines. Here and in the following species the fifth 
legs are entirely lacking in the female. These differences coupled with 
those shown in the details of the structure of the fifth legs of the male 
afford a ready means of identifying the four species thus far known 
in the genus.

Stations 4754; 5553. Eight specimens, including both sexes, were 
obtained in a vertical tow from a depth of 300 fathoms at the first of 
these stations between the Galapagos and Paumotu Islands. Sars 
labeled this as a new species and made the detailed drawings of it 
which are here reproduced. But he had been anticipated by Farran 
(op. cit.) who had described a female from deep water outside the 
Great Barrier Reef of Australia, with which the Albatross specimens 
prove identical. Hence they must bear the name given by Farran. As 
Farran had only the one sex and gave neither description nor figures of 
any appendage, Sars’ figures have been used to supplement those pre- 
sented by Farran and to furnish a basis for the description of the male. 
Female.—Metasome elliptical, a little more than twice as long as 
wide ; head fused with the first segment and somewhat narrowed; fifth 
segment separated from the fourth and symmetrical. Urosome 4-seg-
