The first, third, and last are also permanent residents of 
the plains of India, and breed with us ; those to which an 
asterisk (*) is prefixed range out of India to Burmah, and 
in the case of M, luzoniensis, at any rate, to China and the 
Philippines. P. tristis is said to be identical with the P. 
brevirostris of Strickland, and it may be so, but I have 
been unable to satisfy myself of the fact; the only specimens 
that I have examined, sent from Palestine as P. brevirostris, 
appeared to me to be separable from the Indian bird. As 
for Melanopelargus episcopus, it is found in Burmah, Java, 
Borneo, Celebes, &c. ; and in Africa, from Nubia to 
Caffraria. 
It is probable that all these species breed in Yarkand. 
Ten species appear to be almost peculiar to the central 
or central and western sections of that vast belt of mountain 
ranges which, under various appellations — e.g., the Kara 
Koram, the Hindoo Koosh, the Himalayas, the Kuen Lun, 
&c., stretches, though not without breaks, right across the 
continent of Asia, viz. : — 
499 Ruticilla erythrogastra. 
654 Accentor stropliiatus. 
658 Corvus tibetanus. 
661 „ intermedins. 
668 Pica bactriana. 
737 Carpodacus rubicilla. 
751 Linota brevirostris (PI. XXVI.). 
802 bis Syrrhaptes tibetanus. 
816 Tetraogallus himalayanus.

Not one of these species, so far as I know, occurs fuither 
east than Bhotan. Pica bactriana is replaced even in
