As recorded by the collectors on the labels of the specimens. 



The foregoiug table of careful fresh measuremeuts satisfac- 

 torily indicates the average dimensions and range of variation 

 of this species in the higher latitudes. The female is seen to 

 be considerably smaller than the male on an average, though 

 the dimensions of the sexes inosculate. The range is from 15.} 

 to over 19 in length of head and body, with an average near 

 17J. The tail-vertebra? range from little over 6 to 8}, averaging 

 near 7i. With the hairs, this member. ranges from 9| to 12 

 inches, being generally about 11 inches. F^r from about 1^ to 

 If, generally about 1 ^. Fore toot 2 J to 3f , settling near 3. Hind 

 foot 3J to nearly 4}, generally a little over 4. These extremes, 

 it will be remembered, are those between the largest males and 

 smallest females ; neither sex has so wide a range.
