INTRODUCTION. 
Jerdoii, on the authority of Dr. Adams, assigns it a place in the fauna of India, and Swinhoe in that of 
China ; while it frequents at least the northern portion of Africa. 
191. CoRVUS CORNIX ............ Vol. III. PI. LIX. 
Hooded Crow. 
A resident species in the three kingdoms; breeds in Scotland and Ireland, and but very rarely in England; 
is to be met with in many parts of the European continent, both north and south ; and is particularly common 
in Palestine and Egypt, where it is often the foster-parent of the young of the Great Spotted Cuckoo 
( Oxylophis glandarms). 
192. CoRVUS FRUGILEGUS ........... Vol. III. PI, LX. 
Rook. 
I have retained this bird in the genus Cormis^ many other authors have adopted Lesson’s genus 
and Prof. Kaup’s term of Tryphanocoraoo for it and its immediate allies. L'^nlike the Crows the Rooks are 
gregarious and associate in immense flocks ; they differ from them also in the structure of their bills, the 
peculiar form of which seems adapted for some special purpose, perhaps for the procuration of a particular 
kind of food, such as large underground-deposited larvae of insects, grain, and tuberous roots, as the 
husbandman well knows to his cost. The Rook is even still more omnivorous ; for it will not refuse worms, 
crustaceans, or carrion thrown up by the waves of the sea. Generally dis])ersed over England, Scotland, and 
Ireland. Rooks are only found in a limited portion of the Old World. 
193. CoRVUS MONEDULA ........... Vol. III. PI. LXI. 
Jackdaw. 
Even this indigenous species and its several near allies have been subjected to a generic separation from 
the genus Corms, the term Lycos having been bestowed upon it by Boie, the specific names of the others 
being collaris for the Macedonian bird, datiuricus for the Daurian and Chinese species, neglectus for that 
inhabiting Japan. All are of small size when compared with the true Crows ; they affect different situations 
for the purpose of breeding, resorting to rocks, old towers, and holes in the ground rather than to the trees. 
They are strictly denizens of the Old World. 
Genus Fregilus. 
The Red-legged Crows differ considerably from any of the species above noticed, and are certairdy entitled 
to a separate generic appellation, and accordingly have received three or four. The genus comprises 
but few species, only two being recognized, namely the bird inhabiting Europe, F. graculus, and the 
F. hhmluyensh of the Himalayas.
