A NEW RED-SHOULDERED HAWK FROM THE 

 FLORIDA KEYS 



BY OUTRAM BANGS 



The Florida red-shouldered hawk, Buteo lineatus alleni Ridg- 

 way (type locaUty, Tampa, Florida), occurs as a resident species, 

 with Uttle or no geographic variation, from South Carolina to 

 certainly somewhat south of Tampa on the Florida peninsula. 



In the Florida Keys, and perhaps in the extreme south of the 

 mainland of Florida also, it is replaced by a much smaller form, 

 so different as to require a name, which may be known as 



Buteo lineatus extimus subsp. no v. 



Type adult cf , no. 6899, M. C. Z., from Cape Florida (southern end of 

 Key Biscayne), collected April 5, 1858, by G. Wurdemann. 



Characters. — Similar to Buteo lineatus alleni, and not much different 

 in color though perhaps averaging in general a little darker and richer, but 



much smaller. ., , , , no ^
