76 BULLETIN NO. VII. 



The Canidce possess anal glands affording an odor of more 

 or less power. As has been said, the dogs are found over the 

 entire surface of the globe where carnivorous mammals occur. 

 Even in Australia which has no other endemic placental mam- 

 mal, the Dingo or native dog represents this family, although 

 it may be taken for granted that this species was simply in- 

 troduced in an early period. As regards their origin we know 

 that while no clearly marked representative of the Canidae 

 lived during the Eocene period, there were nevertheless ani- 

 mals which possessed similar characters, more or less masked 

 by inter- relationships with the other carnivorous families. 



In the Miocene true representatives of the group are found. 

 It would appear that the various families of Carnivora have in 

 the main remained in the geographical regions where they 

 were first brought to special development. Thus hyenas are 

 now, as then, restricted to the old world and the raccoons to 

 the western hemisphere. The views of naturalists are as yet 

 by no means identical as to the probable origin of Carnivora in 

 general, most assuming a Marsupial or Marsupial like if non- 

 Marsupial progenitor.* 



The origin of the domestic dog from one or more species of 

 wild dogs cannot be denied. But it is not possible to place the
