BIPDS OF UPPER PEGU. 29 



that I could not ascertain the sex. It measured : Length, 29 ; 

 expanse, 62; tail, from vent, 12*25; wing", 19; bill, from gape, 

 2-05; tarsus, 37; the cere was grey ; bill, greyish-blue at base, 

 changing to dark brown at tip ; iris, hazel ; legs and feet, very 

 pale greyish white.'''' 



This is a very interesting specimen of the true icl/tlii/aefus, Horsf ., 

 which, as I have pointed out in my Eggs and Nests of Indian 

 Bieds, is equally distinct from plumb ens, Hodgson, and humilis, 

 Tern. It is in that particular stage of plumage which Gray and 

 Hard wick figure as Haliaetus lineatus, a stage of plumage which, 

 as far as my present experience goes, is not assumed by plumbem. 



The whole of the head, neck, interscapulary region and 

 coverts, except the greater primary ones, are a light wood brown, 

 each feather tipped with pale fulvous white, and with this color 

 running more or less up the shaft of the feathers, especially 

 on the head. The primaries, their greater coverts, and the 

 winglet, dark brown, blackish towards the tips of the primaries. 

 The greater coverts tipped with fulvous white, and the primaries 

 paling to brownish white at the extreme tips ; secondaries, a 

 rather darker brown than the back, obsoletely barred darker, 

 and narrowly margined at the tips with brownish white. Back 

 scapulars, rump, and upper tail coverts much the same color as the 

 secondaries. Tail, pale dirty brown, with a broad, irregular, 

 blackish band close to the tips, and another somewhat narrower 

 band higher up ; the interspace is very ill-defined, and the basal 

 half of the feathers densely mottled and blotched with dark 

 brown. Chin, throat, ear coverts, and sides of the neck yellow- 

 ish white, each feather narrowly margined with pale rufescent 

 brown. Lower tail coverts, white or nearly so ; rest of the lower 

 parts, pale rufescent brown, each feather with a narrow, central, 

 yellowish white shaft stripe, least narrow on the breast. Axil- 

 laries and lesser lower coverts along the ulna, mingled rufous 

 white and rufous brown, the rest of the wing lining, (except 

 the primary lower coverts,) and the basal portion of the quills, 

 white. The median lower primary coverts, tinged with pale 

 ruf ous ; the greater primary lower coverts also rufescent towards 

 their tips, and with one or two imperfect transverse dark brown 

 bands. On the lower surface of the quills, between the white 

 basal portion and the brown or grey brown tips, the inner webs 

 are greyish white, with four or five strongly marked transverse 

 dark brown bars. The lower surface of the tail is white, becoming 

 tinged with brown towards the tip. There is a broad, irregular, 

 subterminal blackish brown band, and the rest of the feather 

 above this is freckled, mottled, and blotched with dark brown. 



The nostrils are excessively small in this species ; in this speci- 

 men they have not been plugged out with cotton, and they 

 measure exactly 0"13 inch long by 0'09 wide.
