SALIVARY GLANDS OF LOWER PRIMATES

( )ld-World forms here reported with the single exception of the specimen 

 of Lemur moiigoz from the Princeton University Collection (Fig. 13). 



The greater sublingual gland of the lower primates is not to be 

 confounded with the secondary submaxillary gland, since, as shown 

 in the instance of Atelcs (Figs. 11 and 25), both of these components 

 may develop side by side in the same individual. Neither can the 

 greater sublingual element be regarded as forming part of the lesser sub- 

 lingual or Rivinian complex, except in the sense that a number of sepa- 

 rate glands of the latter unite and develop a separate duct. In spite of 

 its close topographical relationship to the lesser sublingual row it is 

 structurally independent of the same and appears as a distinct ele- 

 ment interposed between submaxillary and lesser sublinguals. Con- 

 sidering the junction of the duct with that of the main submaxillary 

 encountered in many forms, it appears more closely associated with 

 the submaxillary system than with the lesser sublingual. 



The greater sublingual gland of the lower primates appears in two 

 forms : — 



A. With independent duct, opening on the parafrenular papilla 

 lateral and usually a little caudal to the orifice of the submaxillary 

 duct. Simla satyrus. Fig. i. 



Cynocephalus sphinx. Fig. 3. 

 Cynocephalus babouin. Fig. 4. 

 Cynocephalus hamadryas. Fig. 5. 

 Macacus cynomolgus, Fig. 6. 

 Macacus nemcslrinus, Fig. 7. 



B. The duct of the greater sublingual gland opens into the sub- 

 maxillary duct a short distance before the latter's termination : —
