Stations 4761; 5231. Originally established by Wolfenden upon 
specimens from the northern Atlantic and briefly characterized. Sars 
gave a detailed description and figures of both sexes in the Monaco 
report, but it is not found in the other planktons. This is the first 
record from the Pacific. 
A male and a female were found at station 4761 in the northern 
Pacific, and another pair found at station 5231 in the Philippines. 
The fifth legs of these two Albatross females differ from the others 
and from the ones described by Sars. They are asymmetrical, the 
right leg larger than the left; in the first one (fig. 382) the marginal 
seta on the left leg is removed a little from the edge on to the surface 
of the leg. There is also a small knob or process on the surface of 
each leg just behind the base of the terminal seta. In the second one 
these knobs are lacking, but there is an extra spine on the right 
leg behind the terminal seta. In all other details these females cor- 
respond exactly with the description and figures given by Sars. The 
differences noted therefore must be regarded as malformations rather 
than specific characters.

Buchaeta barbata Brapvy, Voyage of H. M. S. Challenger, Zool., vol. 8, pt. 23, 
Copepoda, p. 66, pl. 22, figs. 6-12, 1883. 
Stations 4646 ; 4648 ; 4650; 4660; 4661; 4663-4665; 4667 ; 4669; 4671; 
4676; 4679; 4681; 4700; 4707; 4711; 4715; 4719; 4721; 4722; 4757; 
4765; 5185. Identified by Sars from 20 of these Albatross stations 
and from 41 Monaco stations; found also at one Challenger and one 
Stboga station. The genital segment of the female carries a small 
rounded tubercle on the left side at the base of the ventral protuber- 
ance. [The identity of P. barbata has long been questionable. It is 
unfortunate that Dr. Wilson was not aware of Sewell’s discussion 
(1929, p. 155) of this matter and his description of a specimen that 
he had compared with Brady’s type in the British Museum. A careful 
study of these Albatross specimens will have to be made before the 
actual identification can be stated.—M. S. W. ] 
PAREUCHAETA BISINUATA (Sars) 
BHuchaeia bisinuata Sars, Bull. Inst. Océanogr. Monaco, No. 101, p. 12, 1907. 
Pareuchaeta bisinuata Sars, Rés. camp. sci. Albert de Monaco, No. 69, p. 128, 
pl. 33, figs. 16-22, 1925. 
Stations 4765; 5263; 5633. This species was found at 16 Monaco 
and 5 Szboga stations and was fully described by Sars in the Monaco 
report. Most of the Albatross specimens, as well as those in the Siboga 
plankton, were captured in vertical hauls from considerable depths.
