218 Capt. L. H. Irby on Birds 



1. Pal/eornis alexandri. 



Common, in large flocks, in the Terai jungle, at the foot of the 

 hills, during the cold season. It is known to the natives as the 

 Hill-Parroquet. 



2. Pal^ornis torquatus. 



Excessively abundant throughout the year; more particularly 

 so at the middle and end of the rainy season. Breeds in the 

 holes of trees. 



3. PaLtEORNIS cyanocephalus. 



Common in the cold season in jungly districts: probably re- 

 sorts to the hills during the hot weather, as I did not then 

 notice it in Oudb, and it was common in the valleys of Kumaon 

 in May and June 1859. 



4. Falco JUGGER. (Male " Jugger," female '' Luggur".) 

 Seen and killed at Alumbagh, in January 1858. I observed 



what I supposed to have been this Falcon upon many other 

 occasions in the cold season. It is much used by the native 

 falconers, but is rather deficient in pluck, as compared with the 

 Peregrine Falcon. 



5. Falco babylonicus. (Plate VII.) 



A smglc specimen of this Falcon was obtained in October 1858, 

 at Newabgunge Bara Bunki, Oudh, and is now in the Norwich 

 Museum. Mr. Sclater has kindly supplied me with the follow- 

 ing remarks upon this hitherto undescribed bird : — 



" Capt. Irby^s specimen seems to be referable to a new species 

 or distinct variety of true Falcon, most nearly allied to Falco 

 barbarus (of 'The Ibis,' 1859, p. 184, pi. 6; Falco peregrinoides 

 of Temminck), for which Mr. Gurney proposes to use the name 

 Falco babylonicus, the first specimen of it having been obtained 

 in Babylonia by the Euphrates Exploring Expedition. 



" The coloration of F. babylonicus is nearly similar to that of 

 F. barbaruSy but generally lighter, and rather more rufous on the 

 front of the head : the size, however, is nearly one-third greater, 

 being the same as that of F. lanarius of Schlegel. From the latter 

 bird it may be distinguished — (1.) By the absence of the whitish 

 frontal band, the rufous of the vertex extending forwards on to
