176 ANATOMY OF THE SALIVARY GLANDS IN THE CARNIVORA. 



but is of less development. Arising by a broad base from the lip, it 

 rises in a low ridge separating the superior alveolabial and alveobuccal 

 sulci, and narrowing, is attached to the gum on the caudal aspect of 

 the upper canine tooth.

 The parotid (/). which is of looser structure than usual, is almost 

 divided at the meatus auditorius into two lobes, a larger submeatal, a 

 smaller premeatal in position. The latter, occupymg the groove 

 between the masseter and the auricular cartilage, evidently corre- 

 sponds to the cranial border and premeatal process of the gland in the 

 cat. The submeatal lobe is of denser structure, and thicker; caudad 

 it overlies the trapezius and cephalohimieralis. A very rudimentary 

 projection of the dorsal border corresponds to the postmeatal process 

 of the cat, in comparison with which this gland of Gulo is pecuUar 

 chiefly in the great development caudad of the body. The duct (2) 

 emerges from the cranial border near the ventral angle. A tongue of 

 gland tissue accompanies it on its dorsal aspect as far as the sloping 

 border of the masseter ; this is composed of small lobules which are 

 drained by short direct ducts. The orifice of the parotid is at the 

 extremity of a stomal ridge, opposite the interval between the labial 

 cusps of the upper camassial. On the stomal ridge open an orbi to- 

 parotid and seven orbital glands. The former is minute, about 2 

 milhmeters in diameter, placed at the cranial border of the masseter 

 between the deep and superficial facial veins. Its duct passes directly 

 through the buccinator to its orifice opposite the second cusp of the 

 carnassial. In the undisturbed condition of the parts this small 

 gland lies at a level dorsal to that of the parotid duct, where it 

 crosses the border of the masseter, a relation which is important in 

 view of the conditions observ-ed on the opposite side (vide infra). 

 The orbital glands open in . series upon the stomal ridge. Their 

 ducts pierce the buccinator ; their bodies are embedded in the 

 infraorbital fat. That of the first gland is relatively smaller than 

 in the cat. 



The inferior alveobuccal glands (16) are reduced to a small mass in
