Mr. E. Blytli on the Birds of India. 
59. Aq. nasvia. (Savigny, Descr. de PEgypte, Ois. t. 1, et t. 2. 
f. 1; Gould's B. E. pi. 8.) 
Syn. Falco ncevius, F. maculatus , et F. undulatus, Gmelin. 
F. melanaetos, Savigny. Aq. clang a, Pallas. Aq. bifasciata, 
Hornsch. Aq, pomarina, Brehm. Aq. planga et Spizaetos fuscus, 
Vieillot. Spotted Eagle and Brown-backed Eagle, var. a, 
Latham. 
Hab, E. of Europe, Asia, and N. Africa: rare in W. Europe, 
including the British Islands; common in the Bengal Sunder- 
bans; found likewise in the Himalaya (abundantly), and 
in C. and S. India : not on the plains, like the last, but in wooded 
and watery situations. 
60. Aq. hastata. 
Syn. Morphnus hastatus , Lesson. Spizaetuspunctatus, Jerdon. 
Limnaetus unicolor, Blyth, J. A. S. xii. p. 128. 
Hab. Common in the Bengal Sunderbans; and found like¬ 
wise in E. Bengal generally, and in C. and S. India. 
Remark. —This and the preceding three species vary greatly 
in plumage. No. 58 is a miniature of No. 57; No. 59 is larger 
than No. 58, but less robust; and the present species, with 
about the same linear dimensions, is, again, of more feeble con¬ 
formation. A practised eye readily distinguishes either, in any 
phase of colouring. No. 58 is, to a great extent, a devourer of 
eggs and callow broods—an habitual nest-robber, like No. 59. 
Genus Neopus, Hodgson (also Heteropus, Hodgson; 
Onichaetus, Kaup; Ictinaetus, Jerdon, nec Kaup), 
61. N. MALAIENSIS. (PI. Col. 117.) 
Syn. Falco malaiensis, Reinwardt. Aquila et Heteropus et 
Neopus per nig er, Hodgson. Nisaetus'l ovivorus, Jerdon. Black 
Eagle, Jerdon, Catal.* 
Hab . S.E. Himalaya; Nilgiris ; Malayan countries. 
* The Eagle, “ about the size of the Aq. chrysaetos (colour black, but 
head and neck white, tail long and wedge-shaped),” seen at Rupshoo in 
Ladakh by Mr. A. L. Adams (P. Z. S. 1858, p. 471), very decidedly cannot 
have been the present species, as suggested by Mr. Adams. Possibly 
it might have been the great Halia'etus pelagicus (Pallas).
