27. Neotoma fuscipes Cooper. Dusky-footed Wood-Rat. 
A wood-rat supposed to be of this species comes up to at 
least 3000 feet on the west slope of the Sierra Nevada. Their 
large nests were seen in the vicinity of Forest Hill.

29. Zapus hudsonicus (Zimm.) Jumping Mouse. 
This mouse is included in the list of mammals found in the 
Sierra Nevada, on the authority of a trapper, a Mr. Dent, who 
informed me that he had often taken it with poison placed out 
for foxes and wild cats. 
30. Lrethizon epixanthus Brandt. Western Porcupine. 
The presence of this species was noticed in numerous places 
in the high Sierra. Many pine trees about Mt. Tallac and 
Pyramid Peak had patches of gnawed bark, and the animal’s 
quills were frequently found. A single dead specimen was found 
in a meadow near Pyramid Peak on August Io. 
31. Lepus sylvaticus audubont (Baird.) Cottontail Rabbit. 
A few specimens of this rabbit were seen on the Forest Hill 
Divide, at about 3000 feet. They are abundant from the Sacra- 
mento plains up to that altitude or a little less. 
32. Lepus americanus washingtont Baird. Western Vary- 
ing Hare. 
Some of this species were seen about Dutch Flat, in Placer 
County, in the winter of 1891-92. In the high Sierra I am told 
that they are nearly white in midwinter.

‘A few specimens were seen along the base of the mountains 
west of the Carson Valley. 
34. Lepus californicus Gray. California Jackass Rabbit.
