peninsula ; but I have never seen it from the Himalaya, nor from the 

 Soonderbuns, where Aq. noevia is so abundant. — 7, Aq. hastata; Morphnus 

 hastatus, Lesson : Spiza'etus punctatus, Jerdon, Supp. This so much resem- 

 bles Aq. noevia, that it requires some practice to distinguish the two species 

 always, with certainty ; and the same may be said of Aq. noevia and Aq. 

 fulvescens ; but the last named species could never be confounded with 

 the present one. It is altogether a more feeble bird than Aq. noevia, with 

 smaller bill and feet, and proportionally somewhat longer tarsi, but 

 which appear considerably more so from their slenderness. Plumage 

 variable ; but colour always a dead brown, as in Aq. bifasciata ; the neck- 

 hackles smaller than in the other species. The finest adult male 

 which I have procured has the coronal feathers lanceolate, and edged 

 paler ; a sort of supercilium formed by a range of feathers with small 

 whitish tips ; the nuchal hackles also tipped whitish, and the feathers of 

 the lower neck have each a terminal white speck ; three distinct ranges 

 of white terminal spots on the wings ; the tertiaries broadly whitish- 

 tipped ; the breast and flanks beautifully striped with a whitish medial 

 streak to each feather, those of the belly having a further central dark 

 one ; and the lower tail-coverts and tarsal plumes are pale and mottled. 

 Another adult male has the spots generally much less developed, but is 

 otherwise nearly similar. Females are commonly darker brown, with no 

 spots, except occasionally some on the smaller wing- coverts, and especi- 

 ally about the bend of the wing. The young are lighter brown, with 

 sometimes, traces of streaks on the pectoral and abdominal feathers ; and 

 the interscapularies and tertiaries are dark, contrasting strongly with the 

 whitish inner scapularies adjoining. — 8, Hiera'etus pennatus, (Br.) Kaup ; 

 Spiza'etus milvoides, Jerdon : F. lagopus, Bengal variety, Latham. This 

 form chiefly deviates from the robust typical Eagles in its small size, 

 and proportionally small and Buzzard- like beak ; also in shewing a ten- 

 dency to exhibit an occipital crest; in which respect, as also in the 

 whiteness of the under- parts in the young bird, it approximates the 

 Spizaeti. H. pennatus has invariably a white shoulder-spot at all ages, and 

 almost as constantly a white forehead. It is extensively distributed 

 over the country. — 9, Ictinaetus malaiensis, (Reinwardt) Jerdon ; 

 Aquila, Heteropus, and Neopus, perniger, Hodgson : Spiza'etus?? ovivorus, 

 Jerdon, Supp. Remarkable for its very long wings ; its blackish colour 

 throughout, varied with white bands under the tail ; and for the extraor- 

 dinary disproportion of its front toes and claws, of which the inner is
