the cere, and being bordered behind by a broad band of dark 
slaty-brown, which divides it from the rufous of the nape. (2.) 
By the feathers on the back of the neck below the nape being 
bordered with rufous of the same tinge as on the nape. This 
edging is sometimes present in F. barbarus , but never to the same 
extent in F. lanarius . (3.) By the comparative absence of spots 
on the upper portion of the lower surface, in which character it 
nearly agrees with the Abyssinian form of F. lanarius , which I 
take to be strictly Lichtenstein's F. tanypterus. The middle 
claw of F. babylonicus is longer than that of F. lanarius, in which 
respect it also approaches to the structure of F. barbarus. 
Judging from the partial remains of the immature plumage in 
one specimen, it would appear that in this stage the bird most 
nearly resembles F. peregrinus , in which particular it also agrees 
with F. barbarus. 
“Besides Capt. Irby's specimen (No. 1), I am acquainted 
with the following individuals, referable to F. babylonicus :— 
“ 2. An example in partially immature plumage, already al¬ 
luded to as procured by the Euphrates Exploring Expedition in 
Babylonia, and presented by Commander Jones to the Museum 
of the East India Company. This is one of the two specimens 
of f F. peregrinator ' of Horsfield and Moore's Catalogue of the 
Birds of that Collection, entered as ‘ presented by Commander 
Jones;' the other of the two being apparently a young F. pere¬ 
grinus —certainly not F. peregrinator. 
“3. An adult specimen in the Norwich Museum, procured 
from M. Parzudaki of Paris, and said to be from Abyssinia. 
“4. An adult specimen, also in the Norwich Museum, pro¬ 
cured from Mr. Warwick, of which the locality is not known. 
“I may remark that Mr. Blyth has lately (Journ. Asiat. Soc. 
Beng. xxviii. p. 281) distinguished the Indian variety of the Pere¬ 
grine from the European bird as F. calidus —the name being- 
adopted from Latham, who, in his ‘ Index Ornitholog-icus' (vol. i. 
p. 41), conferred that title upon the f Bauri' Falcon of India. 
The present bird, however, does not belong to the group of true 
Peregrines, but rather to that containing F . lanarius , Schlegel, 
F. tanypterus , Licht., F. biarmicus, Temm., and F. barbarus , 
Salvin.
