A LIST OF THE MAMMALS 91 



Otter (Lfiitra canadensis canadensis). This wide roving 

 animal has been recently trapped along the Little Missouri River. 



Long-tailed Weasel (Pntorius longicanda longicanda). The 

 weasel, which during winter when it is white is called the ermine, 

 is quite common here. During the summer of 1910 we saw 4 or 5 

 dead ones along the roads. 



Mink (Putorins vis on vision). The mink is not common. 

 Some trappers report never having caught one, but they occur. 

 My friend, Alvin Mentzer, trapped one on Bull Creek in Feb., 

 1911. 



Skunk (Mephitis (Chincha) hndsonica). This large skunk 

 is uncommon in this area. 



Little Skunk (Spilogale intcrntpta). The "spotted skunk" or 

 "civet cat" is much more common than the large skunk. 



Badger (Ta.ridca ta.vns ta.nts). Quite common. 



Raccoon (Procyon lotor lotor). I know of the killing of 

 two raccoons in Perkins County. 



Puma (Felis concolor). A puma or mountain lion visited 

 the East Short Pines in the winter of 191011. It was doubtless 

 a roamer from the larger Long Pines or Ekalaka Forests. 



[Grizzly (Ursiis Jwrribilis horribilis). In the early go's a 

 grizzly was killed a short distance southwest of Camp Crook. 

 Years before they were doubtless fairly plentiful in this area.] 



[Black bear (Ursus americanus americanus). It is reported 

 that a black bear was seen near the Cave Hills in July, 1910. Bears 

 have been recently killed in the Long Pine and Ekalaka forests, 

 but their day of extermination is here near at hand.] 



[Shrew (Sore.r personatus personatus). Though we have no 

 specimen of the shrews from this county the species certainly is 

 present.] 



Little Brown Bat (Myotis lucifugiis lucifugiis). Abundant 

 about the groves along the Little Missouri and in the forest 

 reserves. (Determined by the Biological Survey). 



[Say Bat (Myotis subulatus). Some of the little brown bats 

 we saw may have been of this species.] 



[Silver haired Bat (Lasionyctcris noctivagaus). This small 

 black bat was probably seen in the canyons of the Cave Hills.]
