SALIVARY GLANDS OF LOWER PRIMATES 



(b) Ateles hyhridus (Figs. 9 and 15). Main submaxillary duct (/) 

 with lateral derivatives (/"), forming the accessorj^ submaxillary 

 glands above described.

(c) Lagothrix humboldtii (Figs. 10 and 16). In addition to the 

 accessory subma.xillary glands and ducts (/"), developed as above (b), 

 the main submaxillary duct carries a secondary submaxillary gland (/')•

II. Forms in which, with the development of the greater sublingual 

 gland, three distinct glands are encountered, the submaxillary (j), 

 greater sublingual (2), and lesser subUngual mass (j). 



Two subdivisions of this group must be distinguished, according 

 to the arrangement of the duct terminals of the two medial 

 glands : — 



/. Submaxillary (/) and sublingual (2) ducts remain distinct and 

 separate throughout their entire extent. Two separate duct orifices 

 appear on each side of the parafrenular papilla.
