144 PRIMATE ALVEOLINGUAL SALIVARY AREA 



duct lies in a glandular furrow connecting the marginal lateral and 

 median strips of primitive oral glands. 



As has been previously pointed out (page 126), the caudal mem- 

 bers of the median series, placed between the submaxillary duct 

 and the side of the tongue, form, when more than commonly 

 distinct, the structures to which the name of the "gland of 

 Weber" has been somewhat unnecessarily appUed. It may further 

 be noted that the ventral accessory submaxillary gland (/") present 

 in the human subject shown in Fig. 10 of Part I is an extensive, 

 long-drawn-out element which drains cephalocaudad into the be- 

 ginning of the main submaxillary duct and evidently occupies

glandiferous territory assigned in other types, as, for example, in 

 the specimen of Cynocephaliis hahoiiin (Fig. 4, Part III, and schema 

 Fig. 16, Part IV), to the glandula subhngualis major (2). This re- 

 ciprocal relation of mutually interchangeable potential glandular 

 fields distributed among available adult glands is again illustrated 

 by the varying proportions exhibited in the above primate series B 

 by the relative de\elopment of the lesser and greater sublingual 

 glands in Macaciis cynomolgus (Fig. 6, Part III, schema Fig. 12, Part 

 IV) and Cynocephalus sphinx (Fig. 3, Part III, schema Fig. 15, Part 

 IV). Also by the replacement in Cynocephalus hamadryas (Fig. 5, 

 Part III, schema Fig. 17, Part IV) of the caudal elements of both the
