Each of the genetic series commences with a genus with no or very 

 simple horns. The next genus or stage presents branched horns, some - 

 times of great complexity. The last term in each is the palmate horn, 

 where a greater or less number of the tines unite to form a plate. These 

 series, as is well known, correspond with the history of the growth of the 

 horns in successive years of the life of each species. 



None of the genera of this family are extinct except Cervalces Scott. 



The following series may approximate a correct representation pf the 

 phylogeny of the genus Bos, expressed in genera.
