ANATOMY OF THE SALIVARY GLANDS IN THE CARNIVORA 1 77 



the vicinity of the angulus oris, almost wholly confined to the buccal 

 region of the vestibule. The condition is evidently to be interpreted 

 as the persistence of the caudal, and the suppression of the cranial, 

 members of such a series as is found in the cat. 



The submaxillary gland is large and of firm structure. The ovoid 

 body lies upon the cephalohumeralis muscle ; its axis is nearly hori- 

 zontal. A tongue-like extension of its cranial pole accompanies the 

 duct as it passes over the digastric muscle, and comes in contact with 

 the fundus of the sublingualis major. This portion is extremely loose 

 in texture and reduced to a series of easily separated lobules. The 

 largest of these, from which the main duct emerges, is placed at, and 

 molded upon, the cranial surface of the digastric, to the mesal side 

 of which it is in part situated. From this a branch of the duct passes 

 to the lateral surface of the muscle and drains two lobules ; the first 

 of them is still in the main in front of the muscle, the second distinctly 

 to its lateral side and in contact with the extension of the submaxillary. 

 This specimen shows in a high degree the effect of the digastric in 

 determining the configuration of the sublingualis major, the duct of 

 which divides at its border to drain the portions of the gland on its 

 ental and ectal surfaces. The tendency of the gland to revolve itself 

 into ecto- and en to-digastric lobes is especially clear in this form, 

 where a remarkably great development of the muscle coexists with a 

 reduced sublingualis major. In the supramylohyoid portion of 

 their course the ducts have the usual disposition ; both are devoid 

 of incrusting lobules. 



The lesser sublinguals (iS) are reduced to half a dozen minute 

 scattered elements at the junction of the arcus palatinus and the 

 alveoUngual gutter, dorsal to the large ducts, and on both sides of the 

 lingual nerve. 



Right side (Fig. 14). The parotid of the same general configuration 

 as on the left lacks the efflorescence of small lobules along the duct. 

 Below its ventral angle there is a small compact ovoid lobule which 

 is drained by a slender duct. This ascends on the lateral surface of 

 the massseter, crosses the parotid duct at the border of the muscle, 

 and opens into its proximal segment on its mesal aspect. In point 

 of debouchment it therefore corresponds to one of the conditions of 

 the orbitoparotid in the cat ; in the situation of its body and the long
