The Centeal Ameeican Extension of the Subteopical Zone and the 



Panama 'Fault.' 



The range of several Subtropical Zone species extends as far north as 

 Mexico. Conspicuous among them is the Towhee-Tanager, Buarremon brun- 

 neinuchus which is found from southeastern Peru to the mountains of the 

 State of Vera Cruz, a distance of over 2500 miles, doubtless a more extensive 

 distribution than is shown by any other subtropical species. Atlapetes 

 guttwalis, a common Colombian subtropical bird, is found as far north as 

 Guatemala, but, as a rule. South American subtropical species do not go 

 further north than Costa Rica. Here, apparently, judging from the data 

 supplied by Mr. Carriker's valuable work, they sometimes descend to lower
