between these three sub-gcncra, and as beings I believe, 
the much-talked-of but hitherto unknown " Shanghar of 
eastern works on Falconry.* 
Two belong to that remarkable Central Asiatic genus, 
Podoces, hitherto only represented, I believe, by a single 
species (P. panderij. From an examination of the two new 
species, as well as from what Dr. Henderson tells me of 
their habits, I have been led to suspect, that instead of 
being Jays, Crows, Magpies, or Choughs, as they have been 
at one time or another considered by different authors, 
these Thrush-Choughs may possibly be only very aberrant 
members of the great Timaline group. 
There is a large crested Steppe-lark which appears to me 
to differ from any yet described, and which may in some 
respects be considered a connecting link between Galerita 
and Certhilauda. 
A Stone-chat of the S. atrogularis type, and a well- 
marked species of the Drymsecine group, which I have for 
the present assigned to the hitherto exclusively Himalayan 
genus Suya, complete our short list of novelties, all of 
which are probably permanent residents of and breed of 
Yarkand. 
Twenty-nine species are widely distributed over the Old 
World, in the northern hemisphere, chiefly in the temperate 
zone, viz. : — 
7 Gypaetus barbatus. 
*13 Hypotriorchis subbuteo. 
*17 Tinnunculus alaudarius. 
**42 Haliaetus leucoryphus. 
, *82 Hirundo rustica. 
*91 Cotyle rupestris. 
125 Coracias garrula. 
*254 Upupa epops. 
351 bis Monticola saxatilis. 
*483 Pratincola rubicola. 
*514 Cyanecula suecica. 
This species, named by me Falco Hendersoni, has since been deter- 
mined by Dr. Jerdon and Mr. Gurney to be F. milvipes of Hodgson. I 
am not quite certain that this identification is correct.
