•1 cm. ; width between the lingual attachments of the palato- 

 glossal folds 2 cm. 



The apex has a mesial notch, and it and the lateral borders are 

 covered with fungiform papilla? which are more numerous and 

 prominent than in the species already described. The structures 

 mentioned on page 278 are absent. 



The Circumvallate Papilla?, (text-fig. 23 E & F). 



Four vallate papilla? are arranged in two pairs — anterior and 



posterior. The former correspond to the lateral papilla? of the 



triangular type, and the latter occupy the position of the posterior 



papilla. The posterior papilla? are close together (text-fig. 23 E).

The tongue of Cercopithecus sabceiis. 



The anterior papilla? are surrounded by clear, smooth Valiums. 

 The posterior Valiums are similar to the anterior ones, or are very 

 prominent and crowded with conical papilla? (text-fig. 23 F). 



The vallate area contains many conical and a few fungiform 

 papilla?. The former vary greatly in size, and they were very 

 large in a young specimen which I examined. 



The papilla? vary greatly in their degree of projection (text- 

 fig. 23 E),
