12 AUSTRALASIAN ANTARCTIC EXPEDITION. 
four expeditions that have collected off the. coast of South Victoria Land, in the Ross 
Sea, between the meridians of 163 and 173, have altogether reported 97 members of 
these groups of mollusca. From the Davis Sea the “Gauss” Expedition reported 122 
species, to which the present inquiry added 12. A difference in collecting, rather than 
a difference in the fauna, is represented by these figures. 
Sration IV. 
Approaching the coast of Wilkes Land on January 2nd, 1914, the trawl was lowered 
in South Lat. 65° 48’, East Long. 137° 32’, in 230 fathoms, bottom ooze; surface 
temperature —1-4° C. 
The narrative refers to this (Vol. II., p. 266) as unsuccessful. The only mollusca 
obtained were— 
Chlamys colbecki Smith. 
Harpovoluta vanhoffeni Thiele. 
Dentalium majorinum Mabille & Rochebrune. 
Srations V. & VI. 
Supplied no mollusca. 
Sration VII. 
The “ Aurora”’ then entered the Davis Sea, and the remainder of the stations 
were pivoted round the winter station of the “ Gauss.” 
The extensive dredgings carried out here by von Drygalski anticipated a number 
of the species taken by Sir Douglas Mawson’s party. 
On January 21st, 1914, off Drygalski Island, in South Lat. 65° 42’, Hast Long. 92° 10’, 
“the dredge was lowered in 60 fathoms, and a rich assortment of life was captured ” 
(Vol. II., p. 270). On the ground were red algee and small rocks. The mollusca 
consisted of— 
Trichoconcha mirabilis Smith. 
Marseniopsis mollis Smith. 
Trophon shackletoni Hedley. 
Sration VIII. 
Steering towards the winter quarters of the Western Base, a position was reached 
in South Lat. 66° 8’, Hast Long. 94° 17’, where a small dredge of the Ball type was 
lowered in 120 fathoms on January 27th, 1914. There were small granite rocks, but no 
ooze, in the net, and life generally was abundant. 
Philippiella orbiculata Hedley. 
Adacnarca nitens Pelseneer. 
Lima hodgsoni Smith. 
Thracia meridionalis Smith.
