64 THE SMALL-EARED DOG. 



Cranial and Dental Characters. 



The cranial structure of this animal will be best understood on 

 reference to figs. 22-24 (p. 63), which are of the size of life. 



Frontal sinuses are present. It may be well here to note that the 

 nasals do not extend so far backwards as do the nasal processes of the 

 maxilla?. The mandible has a very distinct subangular process, much 

 more marked than in C. cancrivorus, or in the variety described by 

 Lund as C. brasiliensis. 



The third lower molar is exceedingly small. The proportion borne by
