114 Mr. E. Blyth's List of Birds obtained 



2. Aquila imperialis. Tern., v. heliaca, Savigny ; Falco mogilnik and 

 astracanus, Auct. This is the A. chrysaetos of Mr. Jerdon's cata- 

 logue, and most probably also that of Col. Sykes. The skin of a 

 fine specimen, killed in the province of Negwunsing, was brought 

 to me while yet imperfectly dry ; and I have received others from 

 Nepal and Central and Southern India. 



3. A. bifasciata, Hardwicke and Gray; A. nipalensis, Hodgson, 

 As. Res. xviii. part ii. 15. Himalaya and hilly regions of Southern 

 India. This is about the size of the preceding species, but has a 

 weaker bill and feet, and a wider gape ; approximating it, as does 

 also its plumage, to Limnaetus hastatus. 



4. A. TKBvia: a most variable species, to which I think must be re- 

 ferred A. Vindhiana, Franklin, and most probably Falco malaiensis, 

 Reinwardt, together with A. punctata, fuscn and fulvescens of Hard- 

 wicke's published drawings. I have received characteristic speci- 

 mens from Nepal and Central India, and feel tolerably satisfied that 

 the whole of the above names apply to this one species. 



5. A. pennata, ante. 



6. A. Bonelli, to which I greatly suspect should be referred the 

 Nisaetos grandis, Hodgson, or doubtfully cited niveus of Mr. Jer- 

 don's list ; a species most frequent in the Himalaya, but occurring 

 also in the mountainous regions of the south ; it is scarcely, however, 

 a true Aquila, though more allied to this genus than are the other 

 Nisacti of Mr. Hodgson. A. Bonelli is enumerated in Mr. Vigors's 

 list of species procured at Cachemere and on the Himalaya. I have 

 given a minute description of the Indian bird in Journ. As. Soc. 

 Beng. vol. xii. 301-2. 



Ictinaetus (Jerdon) perniger ; Heteropus * (olim Aquila) perniger, 

 Hodgson. This curious bird requires to be introduced en suite of 

 the foregoing eagles. Vide Journ. As. Soc. Beng. xii. 127. 



\(j b. Limnaetus hastatus; Morphnus hastatus. Lesson; L. punc- 

 tatus, Jerdon. I have just procured a fine specimen of this species 

 close to Calcutta, and am now satisfied of its distinctness from L. 

 unicolor, which also inhabits Nepal, and with which I considered it 

 to be identical in J. A. S. B. xii. 128. 



17. Haliaetus Macei; H. lineatus. Gray, represents the first plu- 

 mage, and H. unicolo?-. Gray, the second plumage of this species. 

 "\^ide the published drawings of the late Major-Gen. Hardwicke. 



18. Genus Haliastur, Selby. 



19. Ichthyaetus cultrunguis, nobis, I have already referred (vol. 

 xii. 230) to Haliaetus blagrns. Vide remarks on this genus in 

 J. A.S.B. xii. 304. 



21. Add Milvus atolius. Lesson, as a synonym. 



25 a. There is another vulture, which I believe is the Kolbii, 

 higher up the country, and which I am informed may occasionally 

 be met with here, though I have not seen it. A young specimen 

 from Nepal considerably resembles the young of the common V. ben- 

 galensis v. leuconotus, but has a much more lengthened cere, and a 

 white rump.
