THE AMEEICAX EISOXS.

are one fourth to one third larger than either those of B. americanus or B. 

 lonasus, about equalling in circumference at base those of B. priscus, but 

 are only about two thirds as long as those of B. priscus. In none of the 

 above-enumerated forms, except B. priscus, do the horns exceed a length 

 of ten to fourteen inches, while in B. latifrom they attain a length of nearly 

 three feet, or nearly twice the length of those of B. priscus with a correspondingly 

 greater thickness. 



In the foregoing pages, in discussing the affinities of the bison remains 

 from Georgia, tables of comparative measurements have already been given 

 which include the measurements of some of the remains described by Rich- 

 ardson from the ice-cliffs of Eschscholtz Bay. These tables show, as already 

 noticed, the considerably larger size and heavier character of these remains 

 as compared with those of Bison americanus and Bison lonasus, and their much 

 smaller size (especially of the horn-cores and skull) as compared with Bison 

 latifrons. A few further details are here given, relating more especially to 

 the dentition, the lower jaw, and the metacarpal bones. 



The teeth, as shown by the following table, also indicate that Bison antiquus 

 is intermediate in size between Bison latifrons and Bison americanus, or about 

 the size of Bison priscus.
