THE SUBTROPICAL ZONE AND ITS FAUNAS. 



The Subtropical Zone lies approximately between the altitudes of 5000 

 and 9000 feet, or from the average upper limits of the Tropical Zone to the 

 lower limits of the Temperate Zone. Its inferior boundary is consequently 

 as variable* as the superior boundary of the Tropical Zone, and hence may 

 vary from 4500 to 6500 feet in accordance with the conditions mentioned 

 in outlining that zone. The altitude at which it meets the Temperate Zone 

 is also governed by humidity. Apparently, however, it never exceeds 

 9500 feet, but in the absence of the forest which distinguishes the Subtropical 

 Zone it descends to the level at which forest is encountered. Should the 

 forest be entirely wanting, the zone, so far as birds are concerned, is also 

 missing or but suggested by the occurrence of the few scrub-haunting 

 species like Xanthoura, which are found in it. With them will be associated
