A CONTRIBUTION TO THE ORNITHOLOGY OF GILGIT. 121 
3°6; tail, 3-8; tarsus, 0:9; bill from gape, 0°75; culmen, 0:7. 
These specimens are in full breeding-plumage, and have the 
whole back black. A comparison of the above measurements 
with those which I give of the next species will show that 
M. hodgsoni is not constantly larger than M. personata, although 
on the average it may be a heavier bird. The black back of 
M. hodgsoni seems to be the only constant difference between 
the two forms; but that is certain, and proves that it is 
specifically distinct from MJ. personata. 
111.—Motacilla personata, Gould. (591.} 
Major Biddulph mentions that he did not preserve any 
specimens of this Wagtail during the summer months; but I 
have a number of specimens, shot towards the end of May, 
with pure grey backs; certainly in both sexes of this species 
the back is always grey. Thirty-four adult specimens, shot 
in Gilgit, measure :— Length, 7:4 to 8:2 inches ; wing, 3°3 to 3:9; 
tail, 3°5 to 4:1; tarsus, 0°8 to 1:03; bill from gape, 065 to 
0°76; culmen, 0°63 to 0°7. 
112.—Motacilla alba, Zin. (591 bis.) 
This Wagtail only passes through Gilgit on migration ; it 
is not uncommon in April, when I secured a specimen as early 
as the 13th, and again from the third week in September to 
the first week in November. A comparison of six specimens 
from Gilgit, with twenty Huropean specimens of Motacilla alba, 
shows that the Gilgit birds are of a paler grey colour on the 
back, and have more white on the wing; moreover winter 
specimens of the European bird are tinged with yellow about 
the face, while the Gilgit examples do not show any trace of 
this colour. Those who maintain that J. dukhunensis of Sykes 
must be distinguished from M. alba, would class the Gilgit 
specimens under the former title. 
113.—Calobates melanope, Pallas. (592.) 
Common from March to November, and breeds from May 
to July, ai elevations of 6,000 to 9,000 feet. Females shot on 
the 26th April, when the males had fully assumed the black 
on the throat, had the whole chin and throat pure white. 
114—Budytes viridis, Gmel. (593.) 
This species seems only to pass through Gilgit on the spring 
and autumn migrations, and is never common. Two adult 
males, shot on the 9th May, have the head and nape dark 
bluish grey ; the lores, cheeks, and ear-coverts black, and do 
not show any trace of a pale supercilium.
