 Sharpe has omitted to give a reference. 



According to the authors of the ^Laud Birds of North 

 America/ a third race is found in Florida, diflfering from the 

 typical B. lineatus in its smaller size and in the darker 

 coloration of its immature plumage ; and I am indebted to 

 that work for the materials for the following table of com- 

 parative measurements.

Buteo lineatus : 



Smallest of twenty northern males ll'2o 2-7 1"3 



Largest of twenty northern males 13-5 3-25 1-5 



Smallest of seven northern females 13-35 3*1 1'35 



Largest of seven northern females 14-25 3-2 1-5 



Buteo eUgans : 



An adult male 12-5 2-9 1-4 



A young male 12 2-82 1-35 



A young female 13 2-9 1-52 



Florida race : 



Smallest of twelve specimens (sex 



not given) 109 2-9 1-25 



Largest of twelve specimens (sex 



not given) 12-75 3-2 1-45 



It would probably be convenient and permissible to apply 

 a specific appellation to distinguish this small Florida race ; 

 but I am not aware of this having as yet been done. 



The two next species in Mr. Sharpens work are those which 

 stand under the respective names of Buteo latissimus and Buteo 

 obsoletus, both of which are included by Mr. Ridgway, in his 

 recent paper on the genus Craxirex to which I have already 

 referred, among those Buzzards which have only the first three 

 primaries emarginated ; but this character is, according to my 

 experience, more constant in the first of these species than in 

 the second, the fourth primary being in the latter not unfre- 

 quently sinuated, and in one instance within my knowledge, 

 an adult female from Mexico, in the Norwich Museum, 

 distinctly notched. 



In other respects both species show affinities with the 

 central section of the genus Buteo, of which B. vulgaris is
