VOL. IV.] Notes on a Collection of Mammals. 331 



Badgers are common along the eastern base of the Sierra 

 Nevada bordering the Carson Valley, and also in the lower 

 western slope to at least 2000 feet. 



44. Git to tuscHs (lyinne). Wolverine. 



Mr. Dent informed me that he was sometimes troubled in his 

 trapping by the depredations of wolverines. They made the 

 rounds of his traps, eating such animals as the martin and 

 fisher. He said they were found mostly above 5000 feet in the 

 densest fir and pine timber. 



45. Piitorius vison (Schr.) American Mink. 



A single specimen was seen in a pond in the Carson Valley, 

 Nevada. A poultry yard near by was frequently visited by these 

 animals and the owner had succeeded in trapping several. 



46. Mustcla pennanti Erxleben. Pennant's Martin; Fisher. 

 One individual was seen near the resort on Mt. Tallac shortly 



before my arrival. Mr.* Dent informed me they were the most 

 valuable animals to trappers, and that he frequently secured 

 several dozen during the winter. They prefer the high wooded 

 ridges of the west slope of the Sierras above 4000 feet. 



47. Mustcla americanus (Turton). Martin. 



I learned from Mr. Dent that this species is common in the 

 higher forests and is associated with the fisher. 



48. Urocj'on virginianus virgiiiiamis (Schr.) Gray Fox. 

 Foxes were noticed from the Sacramento plains up to about 



4000 feet, and they no doubt go much higher. 



49. Vulpes fulvus argcntatus (Shaw). Silver Fox. 



This fox is found only in the higher forests. Mr. Dent has 

 frequently trapped it, and in the black stage of the pelage is one 

 of the most valuable fur-bearing mammals, the skins often 

 bringing thirty-five dollars apiece. 



50. Ca7us lupus griseo albus (lyinne). Gray Wolf 



This species has been seen several times by Mr. Dent in the 

 dense forests above 6000 feet, 



51. Ca)iis latrans Sa.y . Coyote. 



The coyote is common on both sides of the Sierra Nevada 

 Mountains, and in summer frequently follows flocks of sheep to
