the cere, and being bordered behind by a broad band of dark 

 slat)'- 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. baj-barus, but never to the same 

 extent in F. hnarius. (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 IMuseum 

 of the East India Company. This is one of the two specimens 

 of ' 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 ]\I. 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 Oruithologicus ' (vol. i. 

 p. 41), conferred that title upon the '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.
