16 AUSTRALASIAN ANTARCTIC EXPEDITION. 
Of these the Acmaa, Athoracophorus, and Cyamium were not taken by the Australasian 
Antarctic Expedition. The rest are represented under the same or other names in 
the following list. The known fauna is raised to 35 indigenous and one introduced 
mollusc, an European Limax. The following were collected from 1912 to 1914 by Mr. 
Harold Hamilton, a son of the pioneer investigator :— 
Lepidopleurus kerguelensis Haddon. 
Hemiarthrum setulosum Dall. 
Plaxiphora aurea Spalowsky. 
Schismope subantarctica Hedley. 
Puncturella analoga Martens. 
Margarella macquariensis Hedley. 
Photinula coruscans Hedley. 
Radiacmea macquariensis Hedley. 
Nacella kerquelensis Smith. 
Nacella delesserti Philippi. 
Brookula sp. 
Lewilitorina caliginosa Gould. 
Lewilitorina hamiltoni Smith. 
Eatoniopsis ainsworthi Hedley. 
Tatea melvilli Hedley. 
Friginatica pisum Hedley. 
Trophon albolabratus Smith. 
Turbonilla lamyi Hedley. 
Phriagnathus hamiltoni Suter. 
Kerguelenia redimiculum Reeve. 
Pronucula mesembrina Hedley. 
Philippiella hamualtoni Hedley. 
Chlamys subantarctica Hedley. 
Chione mawsoni Hedley. 
Rochefortia charcoti Lamy. 
Rochefortia macquariensis Hedley. 
Lascea consanguinea Smith. 
Kidderia pusilla Gould. 
Kidderia macquariensis Hedley. 
Gaimardia trapesina Lamarck var. coccinea Hedley. 
Gaimardia snuthi Suter. 
Saxicava antarctica Philippi. 
About a third of the mollusca reported from Macquarie Island extend to Kerguelen, 
and some range round the pole to the Falkland Islands and New Georgia. 
Probably some here described as new will, in the future, be traced to other 
Subantarctic lands. And I expect that further search will add to the molluscan fauna 
of Macquarie Island, more deep-water and minute species.
