138 SOME CHINESE VERTEBRATES. 
tion. This high isolated range proved the richest field explored during the 
whole trip, and most of the peculiar birds and mammals secured came from it. 
It is to be regretted that so short a time, a few days in the spring and again a 
few in autumn, could be spent there. 
All the altitudes were taken by Mr. Zappey himself with an aneroid. 
We have followed the systematic sequence of Sharpe’s Hand list, but our 
use of the 10th edition of Linné’s Systema will account for the difference in many 
of the names employed. All measurements are in millimeters and the colors 
according to Ridgway’s nomenclature. 
We have compared many of our specimens with material in the U. S. 
national museum, and have received the constant aid and advice of Dr. Chas. W. 
Richmond and Mr. Harry C. Oberholser to whom our sincere thanks are 
tendered. 
TETRAONIDAE. 
TETRASTES SEVERTZOVI Prievalsky. 
Three specimens were taken in western Szechwan, an adult male, at Tachi- 
enlu, 13,500 feet, July 9, 1907, an adult female and a young female about half 
grown at Shuowlow, 14,000 feet, August 19, 1908. 
PHASIANIDAE. 
TETRAOPHASIS SZECHENYII Madardasz. 
Seven specimens, six adults of both sexes and a half grown young male 
were taken in western Szechwan, Ramala Pass, Shuowlow, and Nachuka, 
in August, 1908, at altitudes ranging from 14,000 to 15,500 feet. 
The young is very different in color-pattern from the adult, the plumage 
of both upper and under parts being much marked and variegated with gray 
and buff on a dark brown ground color, giving the young bird a grouse-like 
appearance. 
PERDIX HODGSONIAE SIFANICA Prievalsky. 
Five adults, both sexes, Tachienlu, Ramala Pass, and Lanerhyingpa, 
western Szechwan, 11,000 to 15,000 feet, midsummer. 
This form is certainly only a smaller and otherwise slightly different sub- 
species of P. hodgsoniae. The principal color difference is that P. h. sifanica
