This Bear differed from the Hokkaido Bear, which appeared to 

 be its nearest ally, by its much smaller size and by the marked 

 difi'erences in the shape of the teeth above detailed. 



By the kindness of the Trustees of the Indian Museum, the 

 typical specimen of this interesting Bear had been ceded in 

 -exchange to the British Museum.
