 the Indian Sub-region. The " Palseogean " genera are 

 those which are found in the Indian Sub-region and in 

 more than one of the other three Regions of the Old

 found in the New World as well as in the Old. 



From this table it will be seen that the relations of 

 the Indian Sub-region are about equally divided between 

 the Palsearctic and Ethiopian Regions ; the largest number 

 of genera are registered as " Palseogean," and most of these 

 are common to the three Regions of the Old World. 

 The relations of this Sub-region to the Australian Region 

 are very slight ; with the exception of Canis, it is only 

 among the Bats that we find any common genera.

Owing to our imperfect knowledge of the fauna of the 

 central part of China and of Tibet, it is impossible at 

 present to draw up a complete list of the mammalian
