334 Conspectus of the Ornithology of India. [No. 4. 



Falco orientalis {?), et F. lanceolatus {?), Temminck and 

 Schlegel. 

 Hab. Himalaya, and mountain ranges north of Sylhet : also 

 mountains of Ceylon, and probably therefore those of S. India. 

 47. Sp. cirratus? (Horsf. Zool. Res. in Java, pi. ). 

 Syn. Falco cirratus (?), Gmelin. 

 F. cristatellus, Temminck. 

 F. Lathami, Tickell. 

 Nisa'etus pallidus, Hodgson, young. 

 Falco limna'etus, Horsfield. 

 F. caligatus, Raffles. 

 F. niveus, Temminck. 

 Limna'etus Horsfieldi, Vigors. 

 Nisa'etus nipalensis, crestless var., Hodgson, J. A. 



S. V, 229. 

 Lake Falcon, Bauj Eagle, and probably Jerwied 

 Eagle, Latham. 

 Shah-baz or bdj (' Regal Goshawk'), and Sadal, Hind. ; 

 Lang Tanjbikar, Sum. (Raffles) ; Wura Rawa, Jav. 

 (Horsfield). 

 Hab. In two varieties, India generally, Burma, and Indonesia. 

 Remark. The very common race of Lower Bengal (distinguished 

 above as a variety), occurring also in the Malay countries, and in the 

 sub-Himalayan region, or at least its S. E. portions, has very rarely a 

 developed occipital crest, but in general a mere indication of one, 

 though in one specimen we have seen it 3 inches long. This race also be- 

 comes wholly of a sooty-black with age,* save on the base of the remiges 

 underneath, and the tail underneath except towards its tip. The other 

 race, diffused from the sub -Himalayas all over Hindustan, S. India, 

 and Ceylon, has constantly (so far as we have seen) a well developed 

 occipital crest, sometimes attaining to 5£ in. long, and does not appear 

 ever to assume the wholly black plumage, the young also differing in 

 colour from the young of the preceding variety. Nevertheless, after 

 extensive comparison of specimens, we cannot venture to recognise 



* Analogous to Archibuteo lagopus and A. sancti Johannis, though rarely so in 

 the former of these two species (if different, as M. Schlegel contends) ; also to 

 Astur melanoleucos of S. Africa.
