Todd-Carriker: Birds of Santa Marta Region, Colombia. 83 



as well as on the south slope of the Sierra Nevada (so far as known), 

 where conditions are more normal, the Subtropical Zone appears to 

 occupy the belt lying between about 4,500 feet and 8,000 or 8,500 feet. 

 On the whole, we would place the upper limit of this zone in the 

 Santa Marta region at 8,500 or 9,000 feet, or a little lower than the 

 figures given by Dr. Chapman for the Andean system in Colombia. 



Such Subtropical Zone forms as descend into the Tropical Zone are 

 indicated by an asterisk in the subjoined list, while those which are ac- 

 customed to range upward into the Temperate Zone are similarly indi- 

 cated by a dagger.
