and the fore claws considerably shorter in proportion. The fur is whiter beneath. One from 

 Fort Chadhourne, Texas, again, has very large incisors and large claws. The fur is much 

 brighter and more lustrous than in any other I have seen, and the blackish tips to the hairs 

 impart cloudings of blackish to the shining chestnut of the back. The under parts are pale 

 whitish cinnamon ; the chin is white. The tail is unusually short.

Sp. CH. Upper incisors with a single deep groove placed external to the central line, dividing the surface into two unequal 

 portions, the inner considerably the larger. Fore feet rather longer than the hinder ones. The second claw of the hand 

 extending nearly as far as the fourth. Cheek pouches ample. Tail naked nearly to the base. Color above, plumbeous brown, 

 tinged witli yellowish brown on the sides, and grayish beneath. 



Color yellowish brown in the adult ; young plumbeous? In the young a slight additional groove near the outer edge of the 



This species is of large size and readily distinguished from any other found east of the Mis 

 sissippi river by the single groove of the upper incisors. This groove is not central, as in the 

 species from western Texas, but is situated wholly in the exterior half of each incisor ; the 

 inner plane portion being therefore wider than the outer, which is entirely rounded. The 

 external ears are very rudimentary, consisting merely of a thickened ridge of skin. The tail 

 is, in the stuffed specimen, about one-fourth the length of the body ; as prepared, it at first 

 sight appears entirely naked ; a closer examination with a lens reveals, however, a few scattered 

 hairs. The hand, as far as can be determined from its cramped condition, is a little longer 

 than the hind foot ; the claws are very long, stout, and much curved. The middle claw, 

 measured above, is as long as the palm without the tubercle ; measured below, it is contained 

 about two and a half times in the total length. The second and fourth fingers are nearly equal ;
