from Suapure, of corresponding sex and age, and besides being 

 markedly different in coloration, m 2 is disproportionately 

 smaller and less produced internally. The adult specimens 

 respectively measure: Total length, 965, 973 ; head and body, 

 686, 668; tail, 279, 305; hind foot (approximately from dry 

 skin), 140 (with claws 150), 140 (with claws 148); ear (dry), 

 50, 48. Skull, total length, 137, 134; basal length, 129, 130; 

 zygomatic breadth, 76, 74. These measurements being of 

 males naturally exceed those given of the female type of 

 savannarum. 



Canis aquilus (= Urocyon aquilus Bangs), from the coast 

 region of Colombia, while strongly resembling externally the 

 present group, differs from it in the skull being relatively 

 broader and shorter with rather heavier dentition. While 

 specifically distinct from C. cancrivorus it has only the most 

 remote relationship to the genus Urocyon, which is suggested 

 only by its coloration and coarse pelage.
