*The specific \-alues of the Brown Bears of Alaska cannot be considered 

 as satisfactorily established. The roaming habits of these animals frequently 

 cause them to travel very great distances, even swimming wide rivers and 

 estuaries of the sea. It is not probable, therefore, that closely allied animals, 

 as are all those heretofore described, would be able to maintain their dis- 

 tinctive characters, as they mvist at certain seasons mingle promiscuously 

 together, and bears, like pigs, are not particular in their choice of a mate. 

 Great variations in skulls and in size of individuals occur among all bears. 

 It is most probable that when these forms are treated monographically with 

 amjile materials, the number of species and races will be conspicuously reduced.
