Tlic fossil remains -• 1 1 1 1 « ■ < J .- 1 1 « • man by several geologic ages, and 

 arc distributed in every continent. South America has no representa- 

 tive true wolves except the Falkland Island wolf, and, since the 



fossil forms arc very recent, the dog family must have come down 

 from the mirth over our country ami wandered to the southern ex 

 treinity of the new world. On their way a tew were caughl in the 

 tar and died. Since the does of Australia have left fossil remains, 

 there they certainly must have migrated from Asia, while strange 

 enough, one extinct doe- of South America resembles in the parts 

 of the skull our domestic do<rs and is especially allied to on]- coyote.

One of our fossil wolves is identified as canis indianensis, the 

 Indian wolf of Arabia. This fact gives us a very striking incident 

 of migration and contemporaneous development. Southeastern Asia 



is regarded as the original hon f the family, and to find in Arabia 



the same species as we die; up here in our beds is indeed remarkable. 

 The migration westward, landed them in Arabia ami northeastward, 

 into our continent by way of the Behring Strait. That these two 

 branches should have retained their identity through the centuries 

 and through such varied conditions as wire found in this long migra- 

 t ion. is ast onishing.
