present. The boues, though light and somewhat soft, are still 

 white and in an excellent state of preservation, and, though 

 some are broken, have not suffered much abrasion. The hume- 

 rus of the wolf shows the marks of the teeth of some small 

 rodent. 



Cants Mississippiensis, sp. nov. 

 The remains of this species, consisting of a perfect right 

 humerus, the distal two-thirds of a right femur, an entire 

 left tibia and the greater portion of a right tibia, indicate a 

 species of nearly if not quite twice the bulk of the existing 

 large wolf of the northern hemisphere {Cams lupus), and which 

 liad a stature fully one-tifth greater, the difference between 

 them being nearly as great as that between Cams lupus and 

 (an is latrans. The bones do not differ appreciably in respect 

 to form from those of Canis lupus. Their measurements (given 

 in millimeters), in comparison with those of the corresponding 

 bones of a specimen of Canis lupus (number 268 of the Museum 

 of Comparative Zoology) from Kansas are as follows : —
