former years he has found signs abundant; in the fall of 1905 fresh signs at the head 



of Williams Fork. 



[Mus norvegicus Erxl., House Rat 



Thus far I have not located any of this species in this part of Colorado. Mr. 

 Ball states there are none there to his knowledge.] 



Peromyscus maniculatus rufinus Merr., Tawny Deermotjse 

 Four specimens taken at Marvine Lodge. 



Peromyscus maniculatus nebrascensis Mearns, Nebraska Deermotjse 

 Eight specimens taken at Buford. 



Neotoma cinerea orolestes Merr., Mountain Rat 



One taken at Fitzgerald's. In evidence at Marvine Lodge. Throughout the 

 White River valley [Ball].

Three taken at Buford and one at Fitzgerald's. 



Microtus mordax Merr., Cantankerous Vole 



Two taken at Marvine Lodge. 

 Fiber zibethicus Linn., Muskrat 



In a pond about \ mile below Buford post-office [Bartlett]. Also reported by Mr. 

 Ball. 

 Thomomys fossor Allen, Mountain Pocket Gopher 



Many pocket-gopher diggings were found at Buford but none of the gophers were 

 taken. It is probable that they belong to this species. 



Erethizon epixanthus Brandt, Yellow-haired Porcupine 



Abundant in California Park, summer of 1894, and some at head of Williams 

 Fork in autumn, 1905 [Bergtold]. In all probability they were of this species. 

 White River Valley [Ball].

 About Buford [Bartlett]. 



Lepus townsendi Bach., Townsend's White-tailed Jackrabbit 



Three white-tailed jackrabbits were seen on Little Beaver Creek and one at 

 Buford. Although not collected they were presumed to be of the above species. 



Sylvilagus auduboni baileyi Merr., Bailey's Cottontail 

 Sylvilagus nuttalli grangeri Allen, Black Hells Cottontail 



Only one cottontail was seen on the whole trip, and that between Meeker and 

 Axial. There was no opportunity to secure it. Mr. Bartlett says there are cotton- 

 tails about Buford. I am of opinion that they belong to one of the above species.
