TUNICATA. 21 
slightly echinated on the angles of the test; and one large specimen of the solitary 
form, over 7 em. in length, with slightly echinated ridges on the test. At the same 
locality, and on the same date, were found seven large specimens of the gregarious 
form (in three tubes), measuring up to 7 cm. in length, with well-marked ridges on the 
test and slightly echinated in places; but the shape of the body is that of the typical 
S. fusiformis, and is not in the short rounded condition figured by Dr. Apstein for 
the form S. fusiformis, forma echinata, greg. (Deutsche Siidpolar Exped. 1901-08). 
On this date also were found. 52 specimens of the gregarious form, measuring 
from 1 to 2 cm. in length, and two specimens measuring 4°5 cm., also one specimen of 
the solitary form measuring 6 em. . 
This species was obtained by the ‘Challenger,’ near the Antarctic ice, at 
Stat. 152, Lat. 60° 52’S., Long. 80° 20’ E., so the present is not a new record for 
Antarctic seas. It has also been found, in the gregarious form, at the localities :— 
“Dec. 26 off Island, air 32° F., water 32° F.”—32 small specimens up to 18 mm. 
in length; “Dec. 26 off Island, air 32° F., sea 32° F.”—12 specimens up to 
15 mm. in length; “17. xi. 01”—about a dozen specimens up to 3°5 em. and some 
small fragments of chains. 
From the locality, “16. xi. 01, Lat. 61° 46’ S., Long. 141° 12’ E.,” there are 
204 specimens of the aggregated form up to 4 cm., and of the solitary form up 
to 6 cm. 
The solitary form was also found at “51° 56’ §., 170° 0’ E. ”—one specimen torn, 
and in bad condition, probably measuring 8 cm. ; “Dec. 29, Lat. 69° 25' §., Long. 
175° E., sea 32°5° F., air 30° F.”—one specimen measuring 4°5 cm.; and “ Winter 
Quarters, 29. v. 03, No. 4 hole, 5 fathoms”—one specimen, damaged at posterior end, 
measuring 1 em. 
SALPA RUNCINATA-FUSIFORMIS, var. ECHINATA, Hrdm, 
This was found in the gregarious form on “2. i, 02”—six’ small specimens up to 
2 cm.; and in the solitary form at “Dec. 25, Lat. 67° 5’ 8, Long. 179° 30’ E, 
air 314° F., sea 313° F.”—four large specimens in bad condition, 5 to 6 cm. in length; 
“3, 1, 02”—three specimens, the largest measuring 5°5 cm.; and “8. i. 02”-— 
one specimen, measuring 6 cm. In this specimen the muscle bands are narrower, more 
regular, and less swollen dorsally than in the solitary form of the species. 
SALPA CORDIFORMIS ZONARIA, Quoy and Gaim.—Pallas. 
This was found in the gregarious form at ‘26. xii 01, Lat. 51° 56’ S,, 
Long. 170° 3’ E.”—six specimens (in two tubes) measuring up to about 3°5 em.; and 
in the solitary form at “23. iii, 04, Laurie Harbour,* Auckland Island. Tow-net” 
—one specimen measuring 7°5 cm. in length, with muscle bands up to 1 em. in width ; 
and “ Laurie Harbour, Auckland Island. Surface ”—one specimen measuring 6 cm.
