100 A CONTRIBUTION TO THE ORNITHOLOGY OF GILGIT, 
male 4°35; and five males of H. rufuda have the wing 4'55 to 
4:85, and five females 4°45 to 4:75. Now my Gilgit specimen 
has the rump paling to white towards the tail, and, though 
rather small, must be referred to H. rufula.* 
32.—Cotile rupestris, Scop. (91.) 
A summer visitor, arriving about the third week in March, 
and very common in the lower valleys throughout April and 
May. In the males collected the wings measure 5'1 to 5:4 
inches, and in the females 4:95 to 5. Hight specimens shot 
in spring have dusky streaks and, mottlings about the chin; 
in some this marking is confined to the point of the chin, 
while in others it extends to the throat and cheeks. 
Chelidon urbica, Zin. (92.) 
The House-Martin is a summer visitor, and is very com- 
mon in Gilgit in May and June. A female, shot in Gilgit 
on the 10th May, agrees with many European examples with 
which I have compared it in the colour of the axillaries and 
under wing-coverts, and in all other particulars. Length, 55 
inches; wing, 4°4; tail, 2°6; tarsus, 0°53; bill from gape, 0°5 ; 
the uropygials 0°8 shorter than the outermost tail-feathers. 
Major Biddulph does not include this species in his list, but 
gives the closely allied Chelidon cashmiriensis, which I did 
not obtain; the length of the tarsus in his specimen is mis- 
printed 5 for 0:5. 
34.—Cypselus pekinensis, Swinhoe. (99 quat.) 
This Swift is a summer visitor to Gilgit. It was common 
in the lower valleys throughout May and the first half of 
June, but in July and August was only found at elevations 
of over 9,000 feet. Gilgit specimens agree perfectly with the 
type of Cypselus pekinensis, Swinhoe. This form, as has been 
often pointed out, differs from the European C. apus in being 
paler throughout, with a markedly paler forehead, more white 
on the chin and throat, and with a white margin above the 
anterior part of the eye. The difference is doubtless slight ; 
but on actual comparison of specimens it is manifest. Many 
accepted species do not differ in a greater degree; and it 
seems that a colouration which is constant in such a range as 
from Pekin to Gilgit is worthy of some notice in our nomen- 
clature.

5 inches. Are there two races, a larger and a smaller, included in this species P—
