10 AUSTRALASIAN ANTARCTIC EXPEDITION. 
On December 22nd, 1913, the vessel took up a position about four miles from Cape 
Hunter (Vol. IL., p. 260), South Lat. 66° 50’, East Long. 142° 6’, on the west side of 
Commonwealth Bay. Here, with the Agassiz trawl, “a haul was made in 250 fathoms, 
of ascidians, sponges, crinoids, holothurians, fish, and other forms of life in such quantity 
that Hunter and Hamilton were occupied in sorting the specimens until 5 o’clock next 
morning.” 
The surface temperature was — 1-85 C.; very little ooze came up, and the trawl 
appeared to have skimmed over a continuous sheet of organic life. Towards the end 
of the operation the depth increased, and the following mollusca were labelled as from 
350-400 fathoms :— 
Lnssarca notorcadensis Melv. & Stand. 
Adacnarca nitens Pelseneer. 
Lima hodgsoni Smith. 
Callochiton gaussi Thiele.

Proceeding eastwards, the trawl was next put over on December 28th, close to the 
Mertz Glacier Tongue (p. 263), South Lat. 66°55’, East Long. 145° 21’. “ Beside rocks and 
mud there were abundant crinoids, holothurians, corals, crustaceans, and shells.” The 
surface temperature was —1-8 C. The mollusca are labelled from 288-300 fathoms 
from ooze bottom.
