go SALIVARY GLANDS OF LOW'ER PRIMATES 



2. ATELES HYBRIDUS, 9 



Columbia University Morphological Museum, No. 1961, 



Fig. 9 



A. PAROTID (5) 

 The gland covers the entire area between angle of mandible and 

 external auditory meatus, whose caudal circumference it closely em- 

 braces, sending a small retroauricular process behind the concha. 



B. INTERMANDIBULAR COMPLEX 



{a) The submaxillary gland is di\-ided into a main portion (/) , situ- 

 ated below the mylohyoid, partially under cover of the mandibular 

 angle, and an adjacent supramylohyoid complex of two accessory 

 glands (z"), one lateral, the other mesal to the main duct, 



{b) The lesser sublingual complex ij) forms an eUipsoid mass, whose 

 caudal end abuts against the mesal accessory submaxillary element {i"). 



3. LAGOTHRK HUMBOLDTH 



Columbia University Morphological Museum, No. 1911 



Fig. 10 



A. PAROTID (5) 

 The gland forms a nearly quadrangular subauricular mass, extend- 

 ing below and behind the mandibular angle, and abutting against the 

 main submaxillary gland. The parotid duct is simple without de- 

 rivatives. 



B. INTERMANDIBULAR COMPLEX 



(a) Submaxillary. — The submaxillary group is di\ided into three 

 elements : — 



1. Maiti submaxillary gland (z), globular in shape, below the my- 

 lohyoid (/o), occupying the interval between digastric (p) and the 

 caudal extremity of the parotid. 



2. Accessory submaxillary glands (/"). — A large dorsal mass, and 

 two smaller ventral lobes, surround and empty into the main submaxil- 

 lary duct in the interval between the dorsal margin of the mylohyoid 

 (10) and the digastric (9). 



3. Secondary submaxillary gland (/')■ — A small but well-defined 

 gland lying directly behind the lingual nerve (/j), between it and the 

 larger dorsal accessory submaxillary, and dorsal to the main sub-
