serve to show that floridanus is a well marked race, differing from 

 both bryanti of the Bahamas and mearnsi of central Florida. 



Through the kindness of Dr. Thomas Barbour and Mr. Outram 

 Bangs of the Museum of Comparative Zoology, we have been 

 enabled to examine the two cotypes (cT and 9 ) of this subspecies.' 

 The female, although taken in midwinter (Nov. 19, 1870), is 

 unmistakably of the pale resident Keys race and the male (Dec, 

 1870), although showing no diagnostic characters, is likewise in 

 no way distinguishable from breeding birds from the Florida 

 Keys. 



One female specimen from Everglade is a typical floridanus; 

 another (March 12) is darker above and apparently an inter- 

 grade toward mearnsi. Evidently, intergradation with mearnsi 

 takes place between Everglade and the Caloosahatchee River.
