U. S. P. R. R. EXP. AND SURVEYS ZOOLOGY GENERAL REPORT. 



The fur is everywhere full, especially on the rump. The under surfaces of the feet are 

 broadly and densely furred. 



Measurements of fresh specimen. 



Measurements of skulls. 



1 These measurements are taken from occiput to end of nasals. The length is a little greater to the anterior face of the 

 incisors. 



Of a number of skulls of L. sylvaticus not entered in the list of specimens, the largest (1231, 

 from Washington) measured 3.05 -+- 1.41. This is the largest I have ever seen from the eastern 

 States. The rest ranged mostly from 2.80 to 2.95 in length by 1.35 to 1.49 in breadth. A 

 skull from Fort Des Moines, belonging to one of the skins, had a breadth of 1.55 ; this indicates 

 a very large size.
