concavity between its meatal processes. The duct emerges from the 

 cranial border a short distance from the ventral angle in Mephitis 

 {d) and Ursus thibetanus (e). The enormous gland of Procyon 

 (/) has become quadrilateral by developing from the con^■ex caudo- 

 ventral border a caudal angle extending upon the cephalohumeralis. 

 The parotid thus passes from an ovoid, through the stage of crescent 

 and triangle, to a quadrangular shape as its size increases. In Taxidea

(//) the parotid is not large, but has the quadrangular shape and extends 

 upon the cephalohumeralis. This depends upon the flatness of the 

 head and the large size of the external auditory cartilage, so that rela- 

 tive to the space available for expansion the gland is of large size, and 

 has the corresponding habitus. The same is true of Gulo (g), but 

 there is here, in addition, a large though thin premeatal process. 



The molar glands usually extend from the diastemal fold to the 

 superficial facial vein. The series tends to enlargement at its caudal 

 end, where it may ascend along the border of the masseter (bitch,
