COPEPODS GATHERED BY ALBATROSS—WILSON 293 
largest, and they diminish in size backward, the last one being scarcely 
larger than an ordinary period mark (compare with Pontella meadii, 
fig. 417). 
Urosome one-third as long as the metasome and extremely asym- 
metrical. The genital segment is covered by a dorsal carapace, which 
projects backward over the abdomen and the left caudal ramus. This 
carapace is raised into a dorsal knob at the right posterior corner of 
the genital segment, and is produced into a stout curved spine in front 
of the outer margin of the right caudal ramus. The left side of the 
carapace is raised into a smaller knob at the left posterior corner of 
the genital segment, and is then produced diagonally backward into 
a spatulate process covering the abdomen and most of the left caudal 
ramus. ‘This carapace is in contact with the dorsal surface of the 
genital segment but is raised above the abdomen and caudal ramus. 
The abdomen is 1-segmented and almost entirely concealed in dorsal 
view. The caudal rami are very unequal, the right one nearly twice 
as large as the left and pointed at the tip. Each carries five setae, 
three on the outer margin, one on the inner margin, and one terminal. 
The first antennae reach only to the center of the third thoracic seg- 
ment and are rather slender. The fifth legs are exceptionally long, 
reaching to the tips of the caudal rami but are slender. The exopod 
is four times as long as the endopod and curved inward, with three 
small spines on the outer margin and a large acuminate terminal 
spine. The endopod is bifurcate at its tip for more than a third of 
its length. Total length 4mm. Metasome 3.15 mm. long, 1.30 mm. 
wide. 
Type.—U.S.N.M. No. 74130; station 5553, latitude 5°51’ N., longi- 
tude 120°46’30’’ E., off Joloe, Philippine Islands. 
Remarks.—The urosome shows a marked diagonal asymmetry to 
the left, whence the specific name. The rostrum has a large outer 
and inner eye, and the fifth legs are exceptionally long for a copepod 
of this size.

Established by Dana upon specimens from north of the Samoan 
Islands and appearing only in the Sidoga plankton list. It has been 
reported, however, from the tropical Pacific and Indian Oceans by 
Wolfenden (1905a, p. 1021) and Sewell (1914, p. 287; 1932, p. 377). 
Dana’s female specimens belong to this species, but the male whose 
fifth leg is shown on Dana’s plate 82, fig. 5, 7, is the male of tenuiremis
