CHAPTER XVII. 
REPORT ON ZOOLOGY. 
By Exiot BLACKWELDER. 
INTRODUCTION. 
The studies upon which the report is based were made in the course 
of (a) a journey from Tientsin southward into central Shan-tung, and 
thence eastward to the German port of Tsingtau: (b) a short trip in south- 
western Liau-tung between Niu-chuang and Port Adams; and (c) the long 
march from Pau-ting-fu, in Chi-li, west and southwest through Shan-si and 
southern Shen-si to the Yang-tzi-kiang at Wu-shan. Much the largest 
part of the work was done in the last of these journeys. Brief observations 
were also made along the Trans-Siberian railway. The zoological data 
which were assembled by the writer in the course of this work consist of 
seventy-five specimens of vertebrates representing fifty-six species, a daily 
record of all birds and mammals seen, a series of more or less complete 
descriptions of birds as seen in the field, and numerous notes as to habits, 
food, and other characteristics of various animals.* 
My hearty thanks are due to Dr. C. W. Richmond, Dr. Leonhard Stej- 
neger and Mr. Gerrit S. Miller, of the U. S. National Museum, for their 
generous aid in studying the specimens and descriptions of many of the 
species mentioned in the following pages. I wish also to acknowledge the 
sympathy and broad-minded attitude of the chief of the expedition, Mr. 
Bailey Willis, whose interest greatly facilitated the work in the field. 
CLASS AMPHIBIA. 
ORDER ANURA. (Frogs, toads, etc.) 
Hyla chinensis GUENTHER. ‘

A small company of these bright green frogs was found in a shallow temporary pool 
of water, on the grassy surface of a mountain ridge (6,000 feet, 1,800 meters, elevation). 
The chorus made by them was so loud as to be plainly audible at a distance of 2,000 feet, 
600 meters. 
Specimen No. 6055. North slope of the Ts’in-ling mountains (Lung-t’an-ssi) in 
southern Shen-si, April 26, 1904. 
Bufo sp. (?). 
Very young dark-brown toads, presumably of this genus, were abundant in damp 
grain-fields near Hing-an-fu, Shen-si, in the middle of May. Those seen averaged 1.7 centi- 
meters in length. 
* The collection of 448 beetles secured by the writer has been presented to the U. S. National Museum, 
with the understanding that it be described in some forthcoming publication of the museum. The beetles 
will not, therefore, be discussed in this report.
