244 Dr. T. C. Jerdon's Supplementary Notes 



respectiug this species ; but I have come to the conclusion that 

 A. gularis, Schlegcl, is the same as the northern or Himalayan 

 form of virgatus, but that perhajjs the southern or Malayan race 

 is distinct. Certainly many of the specimens got in the Hima- 

 layas do not differ from SchlegePs figure in the ' Fauna Japonica,' 

 Mr. Thompson^ however, in Hume's ' Scrap-book/ indicates two 

 races even in the Himalayas; and one of Hodgson's drawings 

 appears to represent one of them. I am doubtful whether Blyth's 

 A. nisoides is the young of this or not. 



26. Aquila chrysaetus. 



I have seen this magnificent Eagle occasionally in the upper 

 portion of the Sutlej valley, always at great elevations, never less 

 than 12,000 feet ; but in Ladak it is much more common from 

 10,000 to 11,000 feet, and I used to watch in vain for two or 

 three nights in succession to get a shot at a pair that roosted in 

 a magnificent deep ravine close to where my tent was pitched. 

 It is always said by the hill-people to prey much on Tetraogallus 

 and Lerwa. 



27. Aquila imperialis. 



It has lately been attempted to show that the Indian race of 

 this Eagle differs from the European one, the plumage of the 

 young bird especially differing in a marked degree. Hodgson, 

 too, insisted that his vittala (not vittata, as generally written) 

 is distinct from A. imperialis (his nipalensis) ; and ]\Ir. Hume is 

 inclined to agree with him. Blasius also gives bifasciata, Gray 

 (which is vittala), from central Asia, as distinct from imperialis 

 of Europe. I have not sufficient materials to elucidate or even 

 to add any important particulars on this point; but I may state 

 here that one of Buchanan- Hamilton's figures represents the 

 plumage of the adult European bird with a distinct white shoul- 

 der-patch. 



28. Aquila n^via. 



Many African travellers and naturalists speak of this Eagle 

 as frequently being seen to pursue Falcons, to rob them of their 

 prey. It is, I think, much more probable that the Eagle ob- 

 served was in all cases A. navioides, the Indian representative 

 of which is notorious for this habit, which has not to my know-
