' 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.
