OF THE TONGUES OF THE MAMMALIA.

pedunculated. Some run into the lateral oi-gans (text -fig. 6, 

 FP). 



The Conical Pcqy'dlce. 

 On the anterior two-thirds of the dorsum the conical papillte are 

 strong and coarse, and give the tongue a rough appenrauce. Their 

 disposition in clusters and rows is not very clearly marked, but is 

 maintained. Several groups are arranged in an undulating 

 manner, and the points of the papillse point backwards, back- 

 wai-ds and outwards, or backwards and inwards (text-fig. 6). 

 They conceal several of the fungiform papiilte.

The tongue oi Syl abates hoolock, showing the dorsum, inferior surface, 

 and right lateral organ. 



Behind the vallate jKipHlce the tongue is covered with cylindrical 

 conical forms. On the area lying between the lateral vallate 

 papillfe and the level of the posterior pole of the rampart common 

 to the two mesial vallate papilltTe they are small, but behind that 

 level they are large, and many have strong single processes (text- 

 fig. 9, 15). There are some small cylindrical forms anterior to 

 the vallate papillfe. 



The characters and disposition of the conical papillae on the 

 sides and inferior surface are the same as in all other Anthropoids.
