The California collection of fossils, belonging to the cabinet of Wabash 

 College, Indiana, contains several specimens of teeth which I suppose to 

 belong to Bison latifrons. They were loaned to me for examination through 

 the kindness of Professor E. O. Hovey, and are represented in Figs. 6, 7, Plate 

 XXVIII. They consist of the second and third upper molars, and agree in 

 constitution with the corresponding teeth of the recent buffiilo, and in size 

 correlate with the skull above described and referred to B. latifrons. 



The measurements of the specimens, in comparison with those of the 

 buffalo, are as follows :
