This extinct species was first indicated by a portion of a huge skull, which was 

 found in the bed of a creek falling into the Ohio River, a dozen or more miles north 

 of Big-bone-lick, Kentucky. The specimen is now preserved in the Museum of the 

 Academy. 



Dr. Carpenter described a portion of a skull and a molar tooth of the same species 

 from the banks of the Brazos River, near San Felipe, Texas ; and Dr. Falconer 

 reports the existence of a fine skull from the same locality, preserved in the British 

 Museum. 



Other remains referrable to Bison latifrcms have been obtained from the excavation 

 of the Brunswick Canal, near Darien, Georgia, from Big-bone-lick, Kentucky, 

 Natchez, Mississippi, and the shore of the Ashley River, South Carolina. 



In my memoir on the extinct species of American Ox, page 12, I suggested the 

 probability that the fossil attributed to Bison antiquus might belong to the female of 

 B. latifrons, and with this view, in the present synopsis, I have considered the former 

 as synonymous with the latter, though future discoveries may prove the two to be 

 distinct. 



Prof. Riitimeyer, in his Beitrage, page 41, views B. antiquus as the male and B. 

 latifrons as the female of the same species as the European Bison priscus. So far as 

 the sex is concerned this appears to be reversing the usual order of things, for the 

 more characteristic fossil first referred to B latifrons is of much greater proportions 

 than that relerred to B. atitiquu-'^.
