THE GEOGRAPHY OF MAMMALS 



The Bats of Central America are fairly numerous, and 

 nearly all belong to South American genera. A large pro- 

 portion of them are referable to the Phyllostomatidte, one 

 of the characteristic Mammal-families of the Neotropical 

 Region. 



Finally, as regards the Monkeys, the Marmosets (Hapa- 

 lidte) appear to be represented only by a single species, 

 which is an intruder into the extreme southern end of the 

 Sub-region. Of the other family of American Monkeys 

 (Cebidtv), about eight species, against a total of at least 

 sixty found in the Guiano-Brazilian Sub-region, occur in the 

 Central- American Sub-region. Of these five are peculiar, 

 or not yet ascertained to occur elsewhere. 



The following table gives the statistics of the origin and 

 distribution of the Central- American genera of Mammals. 

 The " Endemic " genera are those confined to this Sub- 

 region ; the " Nearctic " genera are those common to this 

 Sub-region and the Nearctic Region ; the " Neotropical " 

 genera are those common to this Sub-region and one or 

 more of the other Sub-regions of the Neotropical Region ; 

 " American " designates those found in both the Neotro- 

 pical and Nearctic Regions, and " Cosmopolitan " those 

 met with also in the Old World.
