XLVI. — Additional Evidence proving the Australian Pachy- 

 derm described in a former Number of the ( Annals * to be 

 a Dinotherium, with remarks on the Nature and Affinities 

 of that genus. By Prof. Owen, F.R.S. 



In the January Number of the ( Annals of Natural History ' 

 (p. 7) I described some fossils transmitted from Australia by 

 Sir Thos. L. Mitchell, and referred them to the Proboscidian 

 family of Pachyderms, pointing out the close resemblance of 

 the broken tooth (figs. 2 and 3, p. 9) to the molars of the Di- 

 notherium and Mastodon, but more especially to those of the 

 Dinotherium, on account of the size and shape of the trans- 

 verse ridges ; although, as their number in the entire tooth 



Dinotherium Auslrale : one-third nat. size. 



could not be ascertained from the fossil, it could not with cer- 

 tainty be referred to that genus. 



I have this morning been favoured by Sir Thos. Mitchell 

 with a letter containing two figures of the portion of the jaw- 

 bone referred to in his former letter, but which he has not been 

 able to procure for transmission, and these figures prove the 

 Australian Pachyderm to be a Dinotherium, not a Mastodon.
