EODENTIA LAGOMY1DAE LAGOMYS PRINCEPS. 



125 



A single individual of this species was killed by Mr. E. E. Howell of the 

 party upon Mount Nebo, near Nephi, Utah. According to the accounts of 

 the settlers, it is quite common in the Wahsatch range, sometimes attaining 

 a large size. 



This species appears to be perfectly distinct from the eastern one, E. 

 dorsat^ts, which it replaces, as far as known, in North America west of the 

 plains. It has a wide range in latitude, from Mexico to Alaska, and corre- 

 sponding regions in British America. Dr. Coues lately found it quite 

 numerous in the Rocky Mountains at latitude 49 N.

Specimens. 



Quite numerous in the mountains, extending, according to Richardson, 

 from the Rocky Mountains northward to 60 4'. It generally inhabits the 

 higher peaks, above timber-line, in the loose lava and scoria, where it hides, 

 but, in some latitudes, descends to the edges of valleys in the mountains, 

 or even to the foot-hills. At latitude 49, it was found by Dr. Coues very 

 abundant below 5,000 feet.
