Capt. L. H. Irby on Birds 
1. PALiEORNIS ALEXANDRA 
Common, in large flocks, in the Terai jungle, at the foot of the 
hills, during tbe cold season. It is known to the natives as the 
Hill-Parroquet. 
2. PaL/EORNIS 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. PALiEORNIS 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 Oudh, and it was common in the valleys of Kumaon 
in May and June 1859. 
4. Falco jugger. (Male “ Jugger,” female “ Luggur’h) 
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 single 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 f 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. barbarus , 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
