Tue drawing illustrative of the present species was taken from the only specimen contained in the col- 
lection ; but several specimens subsequently brought to this country by Major Franklin and Colonel Sykes 
have afforded further opportunities of examining the species. And from a careful comparison of a consider- 
able number of individuals it would appear that the original specimen from which the drawing was taken was 
a female in adult plumage ; from which the males offer no other difference than that of the usual inferiority 
of size, characteristic of the family. 
The Chicquera Falcon appears to be extensively spread through India. In Bengal and the Dukhun it is 
reported by the above-mentioned travellers to be a bird of common occurrence. 
None of the travellers who have sent to this country specimens of this bird have afforded any information 
respecting its habits and manners: nor are there any details on the subject to be found in the published 
accounts of the species. From its structure, however, it may be presumed that the Falco Chicquera, notwith- 
standing a slight departure, in the somewhat shortened wing, from the more typical form of the family, 
partakes of the bold and predatory habits of the genus; the beak being strong, and the notch so typically 
developed as almost to present a double dentation, which added to its short feet and powerful talons indicate 
that it takes the same place in the Oriental world that the Peregrine and other typical Falcons do in our 
northern regions. 
The skin round the eyes and the base of the bill are yellow; the latter becoming black at the tip; the 
cere naked. The ¢arsi also are yellow; the nails black. The crown of the head, back of the neck, and 
mustaches below the eyes are bright ferruginous brown; the cheeks and throat white. The whole of the 
back, shoulders and secondaries, are beautiful slate-grey, with irregular, obscure bars ; the primaries blackish 
brown. The tail is slate-grey with faint bars of blackish brown, and a broad black band near its extremity, 
each feather being tipped with white. ‘The whole of the under surface is white with barb-shaped markings of 
brown.
