brycnic, even for rodents, having no hair until the twentieth day, and 
not opening the eyes until the thirtieth day. One litter is produced 
each year. 
There is a summer and a winter burrow. The first is temporary, often 
excavated by the male, who leads a solitary, and more or less roving life 
during the time of gestation. The pair hibernates, and the female 
brings forth the young in a more complicated burrow, having at least two 
entrances, and a large side chamber dug above the level of the burrow 
and lined with soft grass. These nests are sometimes a foot in diameter. 
Geographical Distribution.—Richardson found this species abundant 
about Carlton House, on the Saskatchewan. It is abundant at Pembino 
and on the Red River settlements. In the United States it is found 
from Minnesota westward to the Rocky Mountains, and southward to 
Missouri and Western Texas. — 
Through the prairie region it extends eastward to Northern Ohio. I 
do not knew in what part of Ohio Dr. Kirtland observed it. Robert 
Kenpnicott states that its range in Illinois does not extend southward 
beyond latitude thirty-nine degrees. 
Judge Potter, of Toledo, has furnished notes since the report was in 
press on the time of disappearance of certain mammals now extinct in 
Ohio. These we give almost without alteration or rearrangement: 
OnIO STATE Fist HATCHERY, 
TOLEDO, Onto, December 21, 1878. 
ALEMBERT W. BRAYTON, Hsq., : 
Dear Sir: J am this moment in receipt of yours of 18th instant, in reference to the 
Mammals of Chio. I send you a few notes, of which you can make use in your general 
description of the animals named. 
F, concolor, or American Panther, can scarcely be said to have inhabited Ohio for the 
last fifty years. Frem 1835 to 1845 they were occasionally found in the northern part of 
the State. In the latter year, two were killed near Toledo, ene of which I saw, a very 
large one. Since then there has, probably, none been found in the State. 
The Lynx (J’, canadensis) has seldom been seen in Ohio. I killed one near Toledo in 
1848, the last I have had any account of. One was kilied the same year in the same 
neighborhood by a hunter. 
Lynx rufus,common Wildcat, was once quite common in Ohio, and is still frequent in 
the northern counties of the State. 
Canis lupus, the Wolf, is still occasionally found in the northern part of the State, but 
not common. They are fast disappearing. 
Vulpes, the Red, Black, and Cross Foxes are still abundant in most parts of the State. 
They prefer a higher latitude than ours.
