Introductory Note. 
Xototherium tasmanicum was described by me in “ The 
Tasmanian Xaturalist ” for April. 1911, the type of the species 
chiefly resting upon tin- distinctive structure of the humerus, the 
mandible, and characters of the tooth line. In the present 
brochure some osteological characters are added to those already 
detailed, and a recapitulation of such comments as have appeared 
since the creation of the species. The classification of this extinct 
gigantic marsupial is as follows: — 
Order: Marsupialia. 
Kamily: Xototherikhe. 
Genus: Xototherium (Owen). 
Species: tasmanicum (S.P. Now). 
Habitat: Tasmania. Extinct: skeleton in Launceston 
Museum. 
With the exception of the remains from King Island, referred 
to in the text, which came to hand later, these are the only indica¬ 
tions vet brought to light of the former existence of these animals 
off the present mainland of Australia.
