SALIVARY GLANDS OF LOWER PRIMATES 83 



mination of the lesser sublingual line, and not connected with the 

 same, a group of similar glands (not colored in Fig. 2) begins and ex- 

 tends thence from a subramal position into the soft palate. These 

 are the above-defined isthmian glands.

A. PAROTID (5) 



A firm, closely lobulated gland, of hammer shape, extending from the 

 sub- and pre-auricular region to the buccal angle. The broad handle 

 of the hammer envelops the parotid duct entirely and is directly con- 

 tinuous with the main para-auricular portion of the gland. 



This condition evidently represents the full and complete develop- 

 ment of that portion of the parotid complex which in other forms ap- 

 pears as the associate parotid glands connected, as isolated glandular 

 masses, with the otherwise free parotid duct. In this respect the 

 parotid of Cynocephaliis is in strong contrast with the preceding ex- 

 ample of Troglodytes (Fig. 2), while the intermediate condition is 

 shown in Simia (Fig. i). 



B. INTERMANDIBULAR COMPLEX 



(a) Submaxillary gland (/). — A relatively small gland, composed 

 of three loosely lobulated di\asions, situated mainly behind the caudal 

 margin of the mylohyoid (10), a cephalic segment projecting slightly 

 above this margin, and two caudal portions extending below the same. 

 In front of the caudal mylohyoid border a collection of accessory sub- 

 maxillary glands (/") connect by short ducts with the ventral circum- 

 ference of the main submaxillary duct under cover of the caudal ex- 

 tension of the greater sublingual gland (2). The latter opens by a 

 separate orifice on the plica sublingualis. 



(b) Lesser sublingual glands (j). — This complex is relatively re- 

 duced in extent, and confined to the cephalic sublingual area. It
