THE GEOGRAPHY OF MAMMALS 



From this summary it will be seen that the total 

 number of Mammal-genera that occur in Celebes is thirty- 

 one, the greater number of which (twenty in all) are placed 

 under the headings of Palseogean and Cosmopolitan. 

 These are all widespread genera, which do not afford us 

 any particular clue to the origin of the Celebesian fauna. 

 Nine out of the twenty are genera of Bats, which, as has 

 before been remarked, are by nature much less restricted 

 in their range than the true quadrupedal mammals. Of 

 the remaining eleven only two (Mus and Sus) have any 

 extensive distribution in the Australian Region ; the 

 others, although they have, in one or two cases, managed 

 to struggle into adjoining islands belonging to the 

 Australian Region, can in no sense be viewed as Australian 

 genera. 



Of the genera registered in the table as " Australian," 

 two are Bats, which have apparently reached Celebes from 

 the more easterly islands of the Australian Region, where 

 they have a wide distribution ; the other is the genus 

 Phalanger, which has been already alluded to as being the 

 only member of the Marsupial Order found in the Oriental 

 Region.
