N0.1271. REVIEW OF THE HORNED LARKS— OBERHOLSER. 8(f3 
coryf< sihhica Swinhoe, ostensibly adopted by him from Eversmann, 
but so far as it has been possible to ascertain Eversmann had never 
pu])lished this name. Although Dr. Sharpe' synonymizes it with 
ehcesi^ it undoubtedly refers to the form called by him hrandtL Mr. 
Swinhoe, after describing- the bird by comparison with O. alpe^tris^ 
savs of it: "Sedentary and ai)undant in the high regions of Mongolia, 
whence it descends to Pekin in small numbers. This pretty lark loves 
the neighbourhood of the Mongol tents in winter."^ Since the resi- 
dent form of Mongolia — if, indeed, not entitled to separate subspecific 
distinction, as appears quite probable — is evidently nearer the bird 
from the region just south of Lake Baikal than it is to that of the 
Himalayas, the name which applies to it must be used for the Baikal 
form together with all else identical. The Baikal l)ird (from Dauria 
and Kiachta) has been waxw^^ pm'vexi.h^ Taczanowski,^ and this b}^ the 
adoption of the view a])ove expressed becomes a synonym of sihii'ica 
Swinhoe. The form from the Kirghis Steppes in western Siberia, 
described by Dresser as Otocorys hrandti,^ is apparently larger than 
that from Dauria, and a good series would probabl v serve to establish 
its claim to recognition, but otherwise it must be added to the s^^n- 
onymy of sihlrlca. The name Otocorys petrojjhila^ is commonl}' cited 
under this form, but though referring apparently' to the bird from the 
Tian Shan Mountains, it is clearl}^ a noinen nudum., and is entitled to 
no consideration. 
This is the smallest and palest of the forms of longh'osir/s., and 
may readil}- be identified by these characters. In size it is not so dif- 
ferent from ehoesi as from the others, but still is usuall}' considerably 
smaller. Winter specimens occasionally in color resemble longirostris 
and jje/'issa, but in such cases size is an infallible test. 
An adult winter male from Katim Karagai, Siberia, apparentlj^ 
belongs to this race, though it is consideral)ly darker and more grayish 
above than the two other specimens.
