— about three feet in diameter and perfectly sound — cut by them.

State. 
Family LEPORID^E. 
THE MOUNTAIN RABBIT. 
Lepus americanus var. bairdi — A llen. 
Known also as “ Snow-shoe ” and “ Maltese rabbit.” This 
species is confined to the mountains and turns white in winter. 
In a specimen examined the roots of the hairs showed plumbeous, 
then a pale salmon or fawn color. The ears sometimes retain a 
blackish tipping or edging. 
COMMON JACK RABBIT. 
Lepus campestris — Bach. 
Very abundant on the prairies and parks of the State, but not 
found in the woods. This species is identical with that from the 
northerly parts of the West, but entirely distinct from the fol- 
lowing. 
SOUTHERN JACK RABBIT. 
Lepus callotis var . texanus — A llen. 
Said to occur in the southern part of the State as far north as 
the vicinity of Greeley. With the size and general appearance of 
L. Campestris, it may be distinguished by having the top of the 
tail black instead of white as in the foregoing species. 
THE SAGE RABBIT. 
Lepus sylvaticus var. NUTTALLi—Allen. 
Very abundant in the sage brush anywhere. 
Family LAGOMYIDzE. 
THE LITTLE CHIEF HARE. 
Lagomys princeps — Rich. 
Common on the mountains above timber-line.
