Mr. R. B. Sharpe’s Catalogue of Accipitres. 233 
in plates 2 and 3 of the former work, to which figures Mr. 
Sharpe has omitted to give a reference. 
According to the authors of the 'Land Birds of North 
America/ a third race is found in Florida, differing 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.

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 
ser. hi.—VOL. VI.
