240 Mr. J. H. Gurney^s Notes on 
above which are narrow bars of that colour alternating with 
broad bars of dark grey; the upper tail-coverts are an un¬ 
broken rufous, as is the tail itself, except that it is crossed 
about half an inch above the tip with a narrow irregular 
blackish-brown band, nowhere more than a quarter of an inch 
in breadth, and excepting also four very small dark spots 
adjacent to the shafts of the middle pair of rectrices. 
I proceed to refer to another and very rare species, Buteo 
harlani, the type of which (an adult female) is preserved in 
the British Museum, and has been fully described by Mr. 
Sharpe, who also adds a description of the young plumage ; 
but the latter must he cancelled, as Mr. Sharpe informs me 
that it was erroneously taken from an immature example of 
an allied species*. 
In consequence of this error, I think it desirable to insert 
a description of a Buzzard obtained by M. Salle in the 
state of Yera Cruz, and preserved in the Norwich Museum, 
which I believe to be an immature example of the veritable 
B. harlani , though it does not precisely agree with the de¬ 
scription of another immature, hut possibly rather more ad¬ 
vanced, specimen from Texas, given by Messrs. Baird, Brewer, 
and Ridgway in yol. iii. of their work, p. 294. 
The following are the principal measurements of this 
specimen 
inches. 
Culmen from core. 1 
Wing from carpal joint . 16 
Tarsus. 2-5 
Space between the tip of the tibial feathers and 
the base of the toes. 0-3 
Middle toe s. u. T7 
The upper surface of the head is dark brown, with the 
bases of the feathers slightly showing white on the forehead 
adjoining the cere, and also about the occiput; ear-coverts 
dark brown, longitudinally streaked with brownish-black; 
chin and upper throat similarly streaked on a white ground; 
the entire remainder of the upper surface (excepting the 
quill-feathers of the wings and tail) similar to the upper
