segment has a rounded knob on the outer margin near the base, the 
second segment has a short seta near the outer margin. The third 
segment ends in a curved blunt finger process nearly half as long as 
the segment. There is a spine on the outer margin at the center 
of the segment and two more close to the tip outside the finger process. 
On the inner margin at the base of this process are two naked setae, 
the distal one longer than the process, the proximal one the same 
length as the latter. Total length 2.1 to 2.8mm. Metasome 0.8 mm. 
wide. 
Types.—U.S.N.M. No. 74112; station 5102, latitude 14°45’ N., longi- 
tude 120°12’30’’ E.; off southern Luzon, Philippine Islands. 
Remarks.—These fifth legs are almost an exact replica of those in 
bispinosa; the structure of the first antennae and the genital segment 
decisively prohibit inclusion in that species. In fact, there is nothing 
even remotely suggestive of the ventral process on the genital segment 
in any of the other species in the genus.

Stations 6; 54; 5180; 5223. Found at three stations in the Carnegie 
plankton and at two stations in the Monaco plankton but not in the 
other lists. This is one of the rarer species, and these Albatross speci- 
mens constitute the second record from the Pacific area, Sewell having 
reported it from the Indian Ocean (1932, p. 338).

mens, including both sexes, were obtained in the surface tow made 5 
miles south of Suva Lightship in the Fiji Islands. Sars’ drawings 
of the fifth legs of both the male and female are here reproduced, 
together with the characteristic spines on the first basipods, which will 
serve to identify the species. Present in the Carnegie and Siboga 
planktons.
