locality, except that the nuclear mass has more of a canary-yellow tint in these, and 
was a pinker colour in the others. 
Station 325, trap-hole, surface, June 4, 1903, Scotia Bay, South Orkneys. A 
dozen specimens, all rather large, up to 6 cm., and having some red pigment on 
the nucleus. 
Station 416, taken by trawl lowered to 2370 fathoms, but probably captured at 
surface, March 17, 1904, lat. 71° 22’ S., long. 18° 15’ W. About forty specimens, 
much smaller, up to 4 cm. in length at most, all with a pale yellow-coloured nucleus. 
Station 422, vertical net, surface to 800 fathoms, March 23, 1904; temp. 31°1°; lat. 
68° 32’8., long. 12° 49’ W. This jar contains a large matted mass of Salpz, Medusee, 
Macrurous Crustacea, and small fish, also a large species of Sagitta. It looks as if it 
had at one time become dry. The Salpz seem to be all of the aggregated form of this 
species, and are of medium size.
