APPENDIX. 
Family FELIDAE. 
THE COUGAR, OR AMERICAN PANTHER. 
Felis concolor — Linn. 
The collection contains two full-grown specimens of this 
great cat, sometimes called “ the Californian lion,” and much 
dreaded for its depredations upon live-stock. One was killed 
near Boulder by poisoning the carcass of a young horse which 
the panther had destroyed. The other was shot. 
The cougar appears to be rather common in the mountainous 
portions of the State, where two or three are usually killed each 
year, but is only rarely seen on the prairie. 
THE MOUNTAIN LYNX. 
Lynx canadensis? 
The most common Lynx of the Rocky Mountains in this lati- 
tude appears to be a modification of the Canada Lynx, Z. 
canadensis of authors, and is perhaps entitled to varietal designa- 
tion as a geographical race of that species. It may be named 
var. 7nontanus. I have seen similar specimens from elevated 
portions of California. These Lynxes do not seem to be speci- 
fically separable from Z. canadensis , but they are distinguishable 
at a glance from the Lynx rufus , which also occurs in the same 
locality. They are much more abundant than the Z. rufus , and 
numbers are shot or trapped each year. Several well-prepared 
specimens are contained in the collection. 
THE COMMON OR BAY LYNX. 
Lynx rufus — Raf. 
One specimen of the ordinary lynx of the United States — 
which, as just intimated, is not so common in Colorado as the 
preceding species — was shot on Cache-Le-Poudre creek at the 
eastern base of the mountains. 
Family CANID^E. 
THE GREAT GRAY WOLF. 
CANIS LUPUS OCCIDENTALIS— Rich. 
One specimen, full grown, and in fine order. This animal 
is much less numerous than the following species. 
THE PRAIRIE WOLF, OR COYOTE. 
Canis latrans — Say. 
A very abundant animal in Colorado as in most other parts of 
the West, and occurring in the mountains as well as on the plains.
