YAIK RAT.

volume of the Transactions of the Linn-^an So- 

 ciety, but I must observe, that, by some oversight 

 in the conduct of the figure there given, the claws 

 on the fore-feet are represented as only three in 

 number, and are somewhat too long, weak, and 

 curved. The engraving in the present plate is a 

 more faithful representation, and is accompanied 

 by an outhne of the head, in its natural size, as 

 viewed in front, in order to shew the teeth and 

 cheek-pouches. The manners of this species are 

 at present unknown ; but it may be concluded 

 that it lays in a stock of provisions, either for 

 autumnal or winter food. The pouches of the 

 individual specimen above described, when first 

 brought to Governor Prescot, were filled with a 

 kind of earthy substance : it is, therefore, not im- 

 probable that the Indians who caught the animal 

 might have stuffed them thus, in order to pre- 

 serve them in their utmost extent.
