cliflferent and larger animal ; but briefly to make known the more 

 decisive evidence of the former existence of a large IMastodontoid 

 quadruped in Australia, which is afforded by the tooth flgured, 

 on the scale of half an inch to one inch, in the subjoined cuts.

If these figures be compared with those of the molar teeth of 

 the Mastodon anyustidens, reduced to the same scale, in Cuvier's 

 ' Ossemens Fossiles,' 4to, vol. i., ' Divers Mastodontes/ pi. 2. 

 tig. 11, pi. 3. fig. 2, or with that of the more abraded molar, 

 pi. 1. fig. 4, they will be seen to present a generic and almost 

 specific identity. 



The close approximation of the Australian IMastodou to the 

 Mast, angustidens will be appreciated by a comparison of fig. 1 

 mth a similar direct side-view of an equally incompletely-formed 

 molar given by Cuvier, loc. cit. pi. 1. fig. 1 ; but this tooth, being 

 from a more posterior part of the jaw, has an additional pair of 

 pp-amidal eminences ; and if the proportions of the figure of half 

 an inch to an inch be accurate, the European tooth is rather

 smaller than the Australian fossil, not\^dthstanding its additional 

 tubercles and more backward position in the jaw. 



The Australian fossil tooth here described was brought by a 

 native to Count Strzlecki, whilst that enterprising and accom- 

 plished traveller was exploring the ossiferous caves in AA^ellington
