Specimen No. 2. — The papillae which are twelve in number, 

 are arranged in the form of a V, but they do not stand on a 

 raised band of tongue as in specimen number one. Several of 

 them are compound.

A. dorsum ; B. ventral surface. The mucosa has been dissected hack to show 

 Wharton's Ducts ; the arrows point to the actual positions of the sublingual 

 glands, and the dotted lines indicate the positions of the plica? fimbriatfe. 



The Fungiform Fapilke. 

 The fungiform papillaj are very small. Tliey have the same 

 arrangement in clusters and rows as occurs in the Chimpanzee 

 and Gorilla. In the centre of the dorsum they are concealed by 

 long filiform papillae. On the inferior surface of the tongue they 

 are larger than on the dorsum, and they are disposed in lines 

 passing from without iuAvards. A double row foi-ms a prominent 

 arch round the anterior extremity of the frenum (text-fig. 4 B). 



The Conical Papillce. 

 The conical papillae aie marked features on the anterior two- 

 thirds of the dorsum (text-fig. 4), but they are more pronounced 

 in some ilidividuals than in others. They have the same arrange-
