ZOOLOGY. 483 
Specimen No. 6601, juv.; Siau-wang-kién, Shen-si; north slope of the Ts’in-ling moun- 
tains (3,500 feet, 1,050 meters, elevation), May 1, 1903. 
Specimen No. 6067, adult; Ta-ho-pa, valley of the P’u-ho, on the south slope of the 
Ts’in-ling mountains, Shen-si, (1,500 feet, 450 meters, elevation). 
Gecko japonicus (DuUMERIL & BIBRON).

A single specimen of this species was found beneath a sheet of canvas which had been 
spread upon the damp earthen floor of a Chinese inn, at Hua-ma-wan, in central Shan-tung. 
It was sluggish in movement. The Chinese fear these geckos as if they were venomous or 
otherwise harmful. 
Specimen No. 6016; Hua-ma-wan, central Shan-tung, November 13, 1903. 
SUBORDER OPHIDIA, (Snakes, etc.) 
Polyodontophis collaris (Gray). 
Gray: Ann. Mag. of Nat. History, 2d ser., vol. x11, 1853, p. 390. 
Several individuals were seen along the road through the basin of the Han-kiang in 
southern Shen-si. The species appears to have a habitat similar to that of the lizards 
Takydromus and Japalura. It is a slender, active serpent, marked with yellow and 
white bands upon a chocolate-colored background. 
Specimen No. 6071, adult; Shi-ts’uan-hién, southern Shen-si, valley of the Han river. 
CLASS AVES. 
The opportunity to observe and collect birds was much better than 
that afforded by the other classes of animals. A large number of species 
pass the winter even in northern China, and so the ornithological work of 
the party did not cease with the advent of cold weather. The exigencies of 
travel, however, were such that only small specimens could be carried, and 
the time of the zoologist was often occupied with his geological duties at the 
very period when work on the birds might have been carried on to the most 
advantage. 
The collection contains 64 birds, representing 49 species.* It was 
supplemented by descriptions of 81 additional species, individuals of which 
were examined in the hand or seen at short range and described at the time 
of observation. Regarding some of the latter there is necessarily more or 
less doubt. Dr. Charles W. Richmond, of the United States National 
Museum, has kindly studied and identified the specimens. He has also 
undertaken the task of identifying the written descriptions, so far as that 
was possible. For these gratuitous services and many helpful suggestions 
the writer desires to thank Dr. Richmond most cordially. 
*The specimens themselves are now deposited in the U. S. National Museum, at Washington, D. C.
