1872.] RAPTORIAL BIRDS OF INDIA. 73 



feather has a whitish spot at the tip, and so have the last two tertials. 

 The colour of the tertials is a very pale brown. The spots on the 

 wing are most numerous from its bend to the junction of the body. 

 One or two of the upper scapulars are pale-tipped. Nearly all the 

 feathers of the head and neck-hackles have minute pale tips, the size 

 of a pin's head. Most of the abdominal feathers have pale tips ; and 

 the tibial and tarsal plumes are all edged with this pale rufous brown. 

 The lower part of the tarsus is a light sandy brown. The white 

 borders to the upper tail-coverts are most conspicuous. There is 

 very little indication of barring on the central tail-feathers ; but 

 on opening the tail the other feathers are seen to be very distinctly 

 barred with hoary grey. 



E ( cf ). Futtehgurh district, four miles north of the Ganges, 8th 

 November, 1871. — This is an older bird, and is devoid of spots, except 

 at the bend of the ridge of the wing to its junction with the body. 

 On the latter part, or ridge, the spots are so thick as to be confluent 

 (I ought to mention that this is the case in all the specimens as 

 yet noticed). This specimen has no pale tips to the head-feathers ; 

 the well-defined white border to upper tail-coverts has disappeared, 

 and these feathers are now simply very pale brown, with dark shafts, 

 shaded to dull white at the edges and tips. Tail hoary brown, 

 showing no bars above ; it is only on opening them that very obso- 

 lete bars are visible in the inner webs of the outer feathers. The 

 under surface of this bird is of a very uniform hair-brown, paling 

 slightly towards the vent, as also on the tibia and tarsi, the latter 

 being quite sandy on its lower half. There are no pale tips to the 

 abdominal feathers ; and those on the tibial and tarsal plumes have 

 nearly all disappeared. The lower tail-coverts are pale brown, 

 mottled with white. This specimen is in the moult, and the whole 

 bird shows a mixture of old and new feathers. Some of the tail- 

 feathers are only half-grown. 



F ( $ ). Futtehgurh district, extreme south, on the banks of the 

 Kalee Nuddee (river), 19th November, 1871. — This is a still more 

 mature bird ; the spots on the wings have all vanished. The 

 upper tail-coverts are pale brown, with darker central line ; there are 

 no light edges or tips to abdominal feathers, nor are there any light 

 edges to the tibial and tarsal plumes ; the latter are plain brown 

 to junction with foot. Lower tail-coverts light brown, with dark 

 central stripes ; towards the tips they are rather pale. Feathers on 

 the top of the head indistinctly tipped with light brown. Tail, as 

 seen from above, without bars ; but obsolete barring is visible on 

 opening it. This specimen is also in the moult ; the whole bird, 

 especially the coverts of the wings, is of different shades of brown. 

 It is, however, generally a darker bird than any of the others, being 

 almost as dark as some specimens of mature A. neevia. 



A.s is the case with Aquila neevia, this Eagle also is subject to a 

 strong purple gloss, and, like it, has the plumage soft and silky. The 

 primaries and secondaries in the fully adult bird, No. 6, are not 

 barred on the inner webs as in A. fulcescens, but are plain as in
