130 MESSRS. SCLATER AND SALVIN ON THE ASTURINE. [Feb. 11, 
occupying a distinct area, as will be seen by reference to our notes 
below. . 
(3) The isolated species 4. /eucorrhoa, which appears to be a true 
Asturina in structure, but in plumage forcibly calls to mind the Buteo 
brachyurus, Vieill. The latter bird has likewise been referred by 
some authors to Asturina—but, from its lengthened wings, should, we 
think, be either placed with Buéeo or stand by itself under the desig- 
nation Buteola, proposed for it by Bonaparte from Du Bus’s MS. 
The subjoined table may, perhaps, assist in distinguishing the 
seven species in their adult dress :—

Supra in fundo alba, dorso toto et alis extus grisescentioribus ; 
schistaceo frequenter transfasciata: gula alba. Junior, tibiis 
rufescentibus immaculatis. 
Hab. Panama (M‘Cleannan); Western Ecuador (Fraser); Bogota 
(Mus. S.-G.); Venezuela (Goering); Trinidad (Leotaud); Cayenne 
(Buff.); British Guiana (Sehomb.); Lower Amazons (Wallace) ; 
Barra, Borba, Cuyaba et Araguay (Natterer); Wood-region of S.E. 
Brazil (Maz. et Burm.). 
This well-known species is, as will be seen from our list of loca- 
lities, widely distributed in South America. The most northern point 
from which we have seen examples is the isthmus of Panama, where 
many specimens have been procured by M‘Cleannan and Arcé. In 
Costa Rica the next species replaces it.
