MONOOltAPUS OF NOllTU AMEUIOAN KODENTIA. 



ihii 



Mijoilen, or Arvkola ab large, it will be better understood by simply laying the 

 diHereut skulls side by si<le, and looking at the teeth with a pocket-lens. 



Externally, although Cunkulus shares the "lemming" ihape of Mi/odes, 

 it is instantly diatinguisiiod by the absence of external ears, the shortness 

 and dense furring of the feet, the obsolete pollex with rudimentary nail, and 

 the prodigious length of the two middle fore claws, whose size is often more 

 lliun doubled by the singular growth already mentioned. As to the absence 

 of cars, there is indeed a rim or border around the opening, but it cannot be 

 called an auricle. 



We have in America but one species of Cunkulus as far as is known; 

 it is identical with that of Northern Asia. Of the relationships of the sup- 

 posed second species, C. lagurus, we can say notiiing, having seen no speci- 

 mens; but, as alrc.idy intimated, we believe its validity to be open to question.
