CANIS 



313 



The only known characters by which the skull of Canls hqjus 

 can be distinguished from that of the larger domestic dogs is the 

 greater average general size and the relatively larger teeth. In 

 a dog's skull with condylobasal length of 230 mm. the length of 

 upper and lower caruassials is respectively 21*6 and 25 '0 mm. 

 In ten skulls with condylobasal length of more than 200 mm. 

 the average and extremes for these teeth are : upper, 20 • 5 

 (19-22) ; lower, 24 • (22 • 8-26 • 0).* In all the dog skulls which 

 I have examined, representing such different breeds as the pug, 

 fox-terrier, bloodhound, mastiff, ancient Egyptian, ancient 

 Peruvian, Eskimo (Greenland and Alaska) and American Indian, 

 the teeth are strictly of the wolf type, never showing any 

 approach to that of the jackal (fig. 62).

* Winge (Danmarks Fauna, Pattedyr, p. 123, 1908) states that in the 

 skull of a dog from a prehistoric grave (Iron Age) in Denmark, the length 

 is 209, and that of the two carnassials 20 and 22-5 respectively, wbile in a 

 rather large modern "great Dane " the corresponding measurements are 

 255, 22 and 28. This author (p. 124) regards the domestic dogs as derived 

 from Canis aureus. 



t Applied to the wolf of the Pyrenees ; but Schreber's plate nxxxix, 

 the basis of the name, is a copy of Buffon's plate xli, representing an 

 animal brought alive to Paris from Canada.
