264 FURTHER NOTES ON THE BIRDS OF GILGIT. 
there any white discernible on the nape of the neck. The other 
race, which I will call Form B, also has a white patch on 
each side of the neck, which extends round to the back, meeting 
the white from the other side, so as to form a complete demi- 
collar when viewed from above. This is most conspicuous 
in breeding-plumage ; but specimens procured at all seasons 
show some trace of white on the nape. Separating the nine- 
teen males in my collection with reference to this point alone, 
I find they measure as follows :—

N.B.—The last two specimens are in full breeding-plumage. 
The females also show well-marked differences in colour. 
Those which in general appearance much resemble the males 
of Form A in non-breeding plumage, have broad rufescent 
margins to the feathers of the back, the wing-coverts, and 
white secondaries, while the tail-feathers are broadly tipped 
and margined with the same, and there are narrow rufescent 
edgings to the feathers of the head and neck. ‘These I have 
referred to Form A. The others are altogether of a much 
darker tone, having the wing and tail-feathers nearly uniform 
dull brown, with very faint inconspicuous pale edgings, and the 
striations of the head and back very broad and dark, with 
narrow margins, and the whole tone of colouration less rufes- 
cent. These I refer to Form B. Separating twenty-four
