In point of colouring they appear subject to the same va¬ 
rieties as the Common Peregrine [Falco peregrinus). 
The measurements of my two skins are, in inches and de¬ 
cimals : 
(1.) Whole length 13*0; wing 11*25 ; tail 5*75 ; tarsus 1*60 ; 
bill from gape 0*95. 
(2.) Whole length 13*5; wing 11*0; tail 5*0; tarsus 1*7; 
bill from gape 1*0. 
From this last bird Mr. Wolfs drawing is taken. 
16. Hypotriorchis eleonorce. (Eleonora's Falcon.) 
On two successive mornings I had the gratification of ob¬ 
serving this species. We were encamped on the banks of the 
Chemora, on the south side of the hills that skirt the southern 
shore of Lake Djendeli. On the 27th of May I had been out 
to collect specimens of the Alpine Swift ( Cypselus me lb a), many 
of which 1 had seen flying over the plain, and was returning to 
breakfast, when one of four hawks which I had previously been 
watching with some curiosity (not knowing what they were) 
came over my head, and fell to a discharge of dust-shot. It 
proved to be a splendid female of H. eleonorce , in full adult 
dress. The following morning I saw one about the same spot, 
but failed to get a shot. It would appear that this bird is a 
late breeder, as the eggs in the ovary were not at all forward, 
and the perfect state of the feathers showed that no eggs had 
been incubated. The plumage of this specimen retained, for 
some time, a peculiar smell, possibly owing to the nature of its 
food, which, though I neglected to examine at the time, I con¬ 
jecture to have consisted principally of Coleoptera. Of the 
colouring of the fleshy parts of this specimen I have the fol¬ 
lowing note:—Bill blue at the base, black at the tip; cere 
yellowish-blue; legs yellow; claws black; eyelid yellow; irides 
dark brown. 
The Zoological Gardens at Marseilles, when I visited them in 
July 1857, contained three birds marked F. eleonorce. They were 
in the Hobby plumage, and apparently nestlings that had just 
assumed their feathers. 
17. Tinnunculus alaudarius. (Common Kestrel.) 
The Kestrel is very abundant throughout the Eastern Atlas,
