84 SALrVARY GLANDS OF LOWER PRIMATES 



forms a small, almond-shaped mass which lies lateral to and below the 

 greater sublingual and submaxillar^' ducts and extends from the frenu- 

 lum to the ventral margin of the greater sublingual gland, whose 

 lateral surface is sHghtly overlapped by the caudal extremity of the 

 lesser sublingual group. 



This individual presents a remarkable instance in which the glan- 

 diferous field usually assigned to the lesser suhliiigual group is in large 

 part transferred to the intermediate or greater sublingual area. The 

 portion of this gland (2 (blue), in Fig. 3) which extends caudodorsad 

 across the Une of the lingual nerve is, in the majority of the primates, 

 represented by the caudal prolongation of the lateral field of the sepa- 

 rate glandular integers fonning the lesser sublingual series (j (red), in 

 Fig- 3)-

The gland is especially developed in the vertical diameter. The 

 caudal extremity extends well below and behind the mandibular angle, 

 and receives the cephalic pole of the submaxillary in a concavity of its 

 ventral margin and medial surface. On the other hand, the sagittal 

 diameter is reduced, and the greater part of the masseter muscle is un- 

 covered. 



B. IXTERMANDIBULAR COMPLEX 



All three components of this complex are present and well de- 

 veloped. 



(a) Submaxillary gland (i). — Around, globular mass situated below 

 and behind the mylohyoid (10) and digastric (9), largely under cover 

 of the mandibular angle and of the adjacent ventral margin and median 

 surface of the parotid. In front of the lingual nerve crossing the ven- 

 tral circumference of the duct receives a distinctly developed ventral 

 duct from an accessory submaxillary gland (/"). The latter lies be- 

 tween the main duct and the oral border of the sublingual gland. 



(b) Greater sublingual gland (2). This gland opens on the papilla 

 by a short duct, close to the submaxillary orifice, lateral to and a little 

 caudal to the same. The gland forms an elongated tongue-shaped
