bryonic, 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 teroporary, often 

 excavated by the male, who leads a solitary, and more or less roving life 

 during the time of gestation. The pair hibernates, and ihe 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 know in what part of Ohio Dr. Kirtland observed it. Robert 

 Kennicott 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 : 



Ohio State Fish Hatcheky, 



Toledo, Ohio, December 31, 1878. 

 Ai«;mbhkt W. Beayton, Esq., 



Dear Sir: I am this moment in receipt of yours of ISth instant, in reference to the 

 Mammals of Ohio. I send you a few notes, of which you can make usa in yonr general 

 description of the animals named. 



F. concolor, or American Panther, can scarcely be said tj have inhabited Ohio tor the 

 last fifty years. From 1835 to 1845 they were occasionally found iu the norlhern part of 

 the State. In the latter year, two were killed near Toledo, one of which 1 :;aw, a very 

 large one. Since then there has, probably, none been found in the Stp.te. 



The Lynx {F. CLwadensis) has seldom been seen in Ohio. I killed one near Toledo in 

 1848, the last I have had any account of. One was killed the same year in the same 

 neighborhood by a hunter. 



Lyvx »-a/us, common Wildcat, was once quite common in Ohio, and is still frequent in 

 the northern counties of the State. 



Cards lupus, the Wolf, is still occasionally found iu ihe northern part of the State, but 

 not common. They are fast disappearing. 



Vuljoes, the Red, Black, and Cross Foxes are still abundant in most parts of the State. 

 They prefer a higher latitude than onrg.
