the Temperate Zone constitutes approximately '5 per cent of the totaT 

 resident avifauna, while in the Andes it constitutes 9.6 per cent, and 

 no less than one hundred and four species are represented in the 

 Andes, as against only twenty-two in the region under consideration. 

 These facts serve to strengthen the conclusions at which we have al- 

 ready arrived from a study of the two lower zones, with reference 

 to the insular character of the fauna of this region. We proceed to 

 a consideration of the relationships of the Temperate Zone of the 

 Sierra Nevada by comparing it directly with the same zone as it is 

 found in the Venezuelan Andes and Colombian Andes respectively.
