Paramys superbus, sp. nov. 



Established on a single lower incisor. 



The species indicated by this specimen is the largest of 

 the genus as yet known. The tooth is subtrihedral in sec- 

 tion, is stout, and shows but little curvature. The anterior 

 and lateral faces are broad, and the under margin to which 

 the sides converge, is narrow. The enamel is thick and is 

 inflected so as to cover a small portion of the sides as well 

 as the front. 



Measurements. 



Transverse diameter of crown -0062 



Fore and aft diameter of crown -007 



Found at Cottonwood Creek. 



AVES. 



The expedition collected parts of four species of birds ; a 

 feather from Florissant Col. the distal ends of a humerus, 

 and a femur and a portion of the shaft of an ulna (?) from 

 the Bridger beds, but they are all too uncharacteristic for 

 classification or description.
