PRIMATE ALVEOLINGUAL SALIVARY AREA

primate series because it exhibits in the same individual all five 

 potential components of the primate intermandibular salivary field 

 carried to full development in the adult. The observation is of 

 especial importance because it proves, since both structures exist side 

 by side in the same individual, that the gland here described as the 

 "secondary submaxillary" is not an exaggerated "greater sublingual," 

 whose duct joins the submaxillary duct, and whose body extends 

 caudad of the lingual nerve intersection, simulating the s.c. "retro- 

 lingual" gland of Ranvier. 



In this form the main submaxillary gland (i) occupies the ty]3ical 

 position. The duct receives, above the mylohyoid, the drainage of a

dorsal accessory submaxillary gland (/")• It is paralleled, nearly 

 throughout its entire course, along the floor of the mouth along its 

 dorsal margin, by the duct of a secondary submaxillary gland (i') 

 which joins it near the termination. 



In the same situation, on its lateral aspect, the main submaxillary 

 duct receives the duct of the greater sublingual gland (2), in conform- 

 ity to the type of the primate group II, to which it belongs. The 

 single caruncular orifice of this animal drains, therefore, the following 

 individual glandular components: —
