SALIVARY GLANDS OF LOWER PRIMATES 93 



(c) The lesser sublingual group (j) extends from near the frenulum 

 to the lingual nerve, as a flat and relatively narrow ribbon of gland 

 tissue. Its caudal end does not meet the isthmian {S) and palatine 

 mass, which is highly developed and continuous.

A. PAROTID 



The quadrangular gland fits by a concave dorsal margin around 

 the external auditory canal, and by a similar concavity of the ventral 

 border adapts itself to the rounded submaxillary mass. The parotid 

 duct is simple, without accessory derivatives. A distinct crescentic 

 mass of separate glands (7) belonging to the alveobuccal or "molar" 

 series occupies the angle of the Hps and repeats conditions encoun- 

 tered in some carnivores (cf. infra, Part V) 



B. INTERMANDIBULAR COMPLEX 



(a) The submaxillary gland (i) is a rounded mass fitted into the 

 concavity of the ventral parotid margin and divided into three main 

 lobes. 



The submaxillary duct is simple (7). 



(b) The greater sublingual gland is absent. 



(c) Tlie lesser sublingual group extends as a clearly defined glandular 

 mass with distinct oral openings from the sublingual plica to a point 

 caudal of the lingual nerve, covering the lateral aspect of the sub- 

 maxillary duct. 



B. ANALYSIS OF THE FOREGOING INDIVIDUAL DISSEC- 

 TIONS, AND GENER.\L CONCLUSIONS REGARDING 

 THE ADULT SALIVARY ORGANIZATION OF THE 

 LOWER PRIMATES 



The facts just adduced seem to warrant the following conclusions 

 in respect to the adult organization of the saUvary glands in the 

 lower primates.
