1 88 EASTERN ARCTOG^EA. [CHAP. 



ropus, from the French phosphorites, is believed to have belonged 

 to the same family, so that both groups appear formerly to have 

 been widely distributed. 



Summarising the results of the foregoing survey, we may put 

 in a tabular form the leading features of the mammalian fauna of 

 Eastern as distinct from that of Western Arctogsea. In the sub- 

 joined table the letters E., M., O., H. respectively indicate the 

 Ethiopian, Malagasy, Oriental, and Eastern Holarctic regions ; 

 and when a family is represented in any of such regions only in a 

 fossil state, a f is added to the denoting letter. The names of such 

 families or groups as are practically peculiar to the area 'under 

 consideration are printed in italic type ; while extinct groups have 

 an * prefixed.
