SUPPOSING the fauna of the world were reduced to the 

 250th part of Jiving species, then the Primates would be 

 represented by one species only, and this being of course Man, 

 his available menagerie would consist of scarcely threescore 

 species, half of which would be Teleostean fishes. The rest 

 would be composed of a dozen and a half of Singing-birds ; half 

 a dozen each of Lizards and Snakes ; four Eodents ; four non- 

 singing neotropical passerine Birds ; two species each of Wood- 

 peckers, Humming-birds and Bats ; one or two each of Parrots, 

 Pigeons, Fowls and some other Game-birds, Kingfishers and 

 Birds of Prey; and one species each of a Shark, Frog, Toad 

 and Treefrog, Gecko, Kuminant and Carnivore. 



Although this is a somewhat ludicrous calculation, it never- 

 theless indicates what may happen in time to come, it being 

 beyond doubt that many of the smaller groups have had their 

 day and are now on the decline, while others are on the increase 

 and have a future before them.
