COPEPODS GATHERED BY ALBATROSS—WILSON 223 
The antennae, mouth parts, and first four pairs of legs are like those 
of the female, while the fifth legs resemble at first sight those of the 
messinensis male. Closer examination, however, reveals that the left 
leg is fully three-fourths as long as the right. It is 3-segmented and 
the terminal segment is armed with three small protuberances on its 
inner margin; the left endopod has entirely disappeared (cf. fig. 88). 
In the right leg the endopod is considerably inflated, the exopod is 
2-segmented, and the endopod 1-segmented and considerably shorter. 
The proximal segment of the exopod has four processes on its inner 
margin while the distal segment is fringed on its Inner margin with 
short hairs and is bluntly pointed, with two knobs on the outer margin 
near the tip. The endopod reaches beyond the tip of the basal exopod 
segment and is curved, with two acute processes on its inner margin. 
Total length 5.33 mm. Metasome 4.38 mm. long. 
Allotype male.—U.S.N.M. No. 70733 ; station 4664, latitude 11°30’ S., 
longitude 87°19’ W., off Peru. 
Remarks.—About a dozen males only 4 mm. long were taken with 
the others. The fifth legs of one of them are shown in figure 88. This 
figure indicates that even if the left endopod has entirely disappeared 
in the adult male it was certainly present during development. On 
page 65 of his Monaco report Sars calls attention in giving the charac- 
teristics of the genus Huchirella to the very remarkable presence of 
paired egg strings in three species. He showed two of the species in 
messinensis (pl. 19) and brevis (pl. 21), and as he had already exam- 
ined the Albatross plankton this must be the third species to which he 
referred. 
EUCHIRELLA GRANDICORNIS [Sars MS.] Wilson, new species 
PLATE 9, FicuREs 98-100; PLate 10, Ficures 101-106 
Station 4681. A male and a female from this station were identified 
as a new species by Sars and given the above name. 
Female.—Metasome subcylindrical, flattened a little on the ventral 
surface, three times as long as wide and narrowed at both ends. Head 
fused with the first segment ventrally but partially separated dorsally 
with a well-defined frontal crest. Fourth and fifth segments fused 
with the posterior corners projecting backward to the center of the 
genital segment. Urosome 4-segmented, less than a fourth as long 
as the metasome and about the same width throughout. Genital seg- 
ment as wide as long, perfectly symmetrical, with straight parallel 
sides; abdomen 3-segmented, the segments nearly the same length, 
which is half the width. Caudal rami at the corners of the anal 
segment and divergent, each one-half longer than wide, with five short 
setae and a much longer inner seta.
