4. Canids. 
Scott, Trans. Amer. Phil. Soc. xvii, p. 75, concludes that the evolution 
of Canis took place in North America, the ancestry being traced 
through Cynodesmus of the John Day Beds to Daphcenus of the White 
River, and thence to the Creodont Miacis of the Bridger ; Cynodictis 
forming a lateral branch. For brain of Canidcc , see Rudinger,
