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' S., long. 12 49' W. This jar contains a large matted mass of Salpse, Medusae, 

 Macrurous Crustacea, and small fish, also a large species of Sagitta. It looks as if it 

 had at one time become dry. The Salpse seem to be all of the aggregated form of this 

 species, and are of medium size. 



Station 391, "Tunicate," water-bottle on sounding wire (depth of sounding, 2630 

 fathoms), February 27, 1904. A single, very large specimen of the solitary form, 

 fully 8 cm. in length, but rather damaged, with a chain measuring at least 4 cm.
