exopod segments combined. Terminal segment of second exopod 
with three outer spines, the middle twice the size of the others, the 
notch inside of its base considerably deeper than in Farran’s figure. 
Total length 5.51 mm. Metasome 4.20 mm. long, 1.65 mm. wide. 
Male.—Slightly smaller than the female but with similar propor- 
tions; the antennae, mouth parts, and first four pairs of legs also 
similar. The fifth legs show distinctive characters; the second basi- 
pod of the right leg is considerably swollen and one-half longer than 
wide. The endopod is slender and as long as the basal exopod seg- 
ment; the terminal exopod segment is a fourth shorter than the 
basal segment and well curved. The second basipod of the left leg 
is cylindrical and reaches the center of the right endopod. The 
left endopod is almost a third as long as the proximal exopod seg- 
ment and is enlarged at its tip. The terminal armature of the end 
segment of the exopod is shown in figure 188, with the three rami 
nearly as long as the segment itself. Total length 5.25 mm. Meta- 
some 4 mm. long, 1.33 mm wide. 
Allotype—U.S.N.M. No. 67261 (without station data). 
Remarks.—This species most resembles sa7s? but is little more than 
half as large, and the details of the genital protuberance in the female 
and of the fifth legs in the male are quite different (cf. fig. 250).

PLATE 19, FrcuRE 250 
Euchaeta sarsi FaRRANn, Fisheries Ireland, Sci. Invest. for 1906, pt. 2, p. 41, pl. 3, 
figs. 15, 16, 1968. 
Stations 4671; 4679; 4701; 4753; 4760; 4800; 5063; 5287. Identified 
by Sars from 4 of these Albatross stations and from five Monaco sta- 
tions and obtained by Scott at one Stboga station. 
PAREUCHAETA SCOTTI (Farran) 
Euchaeta scotti Farran, Fisheries Ireland, Sci. Invest. for 1906, pt. 2, p. 42, pl. 3, 
figs. 11, 12, 1908. 
Stations 4655 ; 5287. Identified by Sars from the first of these Alba- 
tross stations off the Peruvian coast and from four Monaco stations. 
As the latter were ail in the northern Atlantic, these Albatross speci- 
mens constitute a first record from the Pacific.
