COPEPODS GATHERED BY ALBATROSS—WILSON 281 
away from the surface of the protuberance. It is the latter pad that 
forms the protrusion seen in the lateral view and thus furnishes a 
ready means of identification.

Identified by Sars from three of these Albatross stations and from 18 
Monaco stations. Both sexes were fully described in the Monaco re- 
port. It does not occur in any of the other plankton lists.

Stations 15; 16; 4583; 4585; 4634; 4637; 4638; 4646; 4648; 4652; 
4659; 4663; 4664; 4665; 4667; 4673; 4676; 4679; 4681; 4687; 4700; 
4701; 4707; 4711; 4718; 4715; 4717; 4719; 4721; 4722. Originally 
reported from the tropical Pacific, this species was next recorded from 
the tropical Atlantic in the Carnegie plankton. Giesbrecht’s types 
were females but these Albatross specimens include both sexes. Since 
the only description of the female is very meager, it is redescribed here, 
along with a first description of the male. Both are based upon repro- 
ductions of Sars’ excellent pencil drawings. 
Female.—Metasome elliptical, three times as long as wide and nar- 
rowed but little at each end, the frontal margin sharply pointed and 
the rostrum almost at right angles to the body axis. The posterior 
corners of the thorax are smoothly rounded, with a few scattered 
hairs. Urosome two-fifths as long as the metasome and 4-segmented ; 
the genital segment isa little wider than the abdomen and twice as long 
as wide, the lateral margins somewhat convex. The ventral protu- 
berance is smoothly rounded and projects a distance equal to the thick- 
ness of the segment itself. The basal segment of the abdomen is 
longer than the other two segments combined, while the anal segment 
is very short. The caudal rami are longer than the anal segment and 
somewhat divergent; the appendicular setae are strongly geniculate 
and much lengthened. The ventral surface of the abdomen is some- 
what hairy as seen in the lateral view.
