266 FURTHER NOTES ON THE BIRDS OF GILGIT. 
can affect totally to ignore when treating of two very closely 
allied species found in the same locality; or it may be that 
some of those classed as females would have been found by 
more careful examination to be males that had not got rid of 
female plumage. Whatever may be the explanation of this, 
I believe that we have here two species. 
The smaller species of Chat, which I have called Form B, 
is evidently the P. indica of Blyth; but itis more difficult to 
say which is the P. maura of Pallas. 
74.—Saxicola opistholeuca, Strickland. (488.) 
I find that I got four specimens of this Chat in Gilgit— 
three at the beginning of April, and one in December. The 
young bird previously referred to (Zbis, 1881, p. 55) turns 
out, on further comparison, to be a young specimen of 
S. morio. There is no reason to suppose that S. opistholeuca 
breeds in the district. 
75.—Saxicola picata, Blyth. (489.) 
Dr. Scully and myself have brought away from Gilgit 181 
specimens of this Chat. Of these there are 102 adult males, 
46 adult females, the rest being of both sexes in different 
stages of immaturity. I can add little to what has already 
been said about this bird. The specimens of the males before 
me show every gradation, from the creamy-white head to jet- 
black ; but those with pure black heads are the most numerous ; 
next in number come those in different phases, while those 
that have entirely white heads are the scarcest. 
The adult females are all of the same type, with the excep- 
tion of a single specimen, which differs in having the lower 
throat nearly black. Dr. Scully tells me that he has also 
a precisely similar female specimen. There is no doubt as to 
the determination of the sexes of these two specimens ; but the 
wing-formula is the same as in all other specimens of 
S. picata. Among the immature specimens females are 
undistinguishable from males. 
77.—Saxicola morio, Hempr. & Ehr, (490.) 
Dr. Scully and I have brought away from Gilgit alto- 
gether 153 specimens of this Chat. Dr. Scully’s assertion of 
the identity of this species with 8S. hendersoni must, I think, 
be accepted. The specimens of adult males show clearly the 
gradation of plumage from the black, with pure-white cap, of 
the breeding-stages, to the S. hendersoni type of autumn. 
Two specimens, of 27th April and 23rd May, show a few faint 
brown specks on the back and head. Four specimens, of 
18th, 21st, and 25th July, have the freshly moulted secon-
