each other in the ventral mid-cervical line and interlock with the 

 caudal prolongations of their respective parotids. 



In Lemur mongoz (Fig. 13, Part III) the glandular development 

 is less pronounced, but the subma.xillary gland, composed of three 

 lobes, fits closely into 

 the concave caudal 

 border of the overlapping 

 parotid. 



Accessory salivary 

 glands are present and 

 well developed in both of 

 these animals. 



In Nyctipithecus the 

 caudal end of the lesser 

 sublingual group, after 

 crossing obliquely ceph- 

 alodorsad on the lateral 

 aspect of the submaxil- 

 lary duct, abuts directly 

 against a dense glan- 

 dular mass (Fig. 8, Part 

 III, 8) which occupies 

 the arcus palatinus 

 (isthmian glands) and be- 

 comes continuous with 

 the glands of the soft 

 palate. 



In Lemur mongoz the 

 lesser sublingual glands 

 extend caudad beyond the 

 lingualis-submaxillary 

 duct intersection, while 

 the oral angle is occupied 

 by an alveobuccal series 

 of glands (Fig. 13, Part 

 III, 7) which fills as a 

 crescentic mass the inter-
