VARIATION. 



In the small series at hand, in which the majority of the specimens 

 are from Locust Grove, Lewis County, New York, Ravenna, Ohio, and 

 Magnetic City (foot of Roan Mountain), North Carolina, no api)reciable 

 geographical variation of color or size can be detected. A specimen

from Quebec is not different from the others, except that it is a little 

 duller in color and browner, probably due to its having been in the 

 collection for a long time. 



There is, however, considerable variation Avith age. The feet, tail, 

 and base of snout, which are dark brown in young individuals, become 

 progressively more hoary with increasing age and are eventually pure 

 white. In all the specimens in which the tail is hoary, the teeth are 

 more or less worn, and sometimes very greatly. The specimen which 

 shows this albinism most strongly (No. 510, Merr. Coll., Locust Grove, 

 New York), has stronger ridges on the skull than any other in the series.
