BR. C. F. SONNTAG ON THE ANATOMY 



The Conical Papillce. 



Tlie conical papillae are arranged in tlie typical form, and the 

 direction of the points takes the usual covirse. Those on the base 

 are large. 



The papillae have cylindrical, conical or compressed bodies, and 

 have one or more points. 



At the insertions of the palato-glossal folds there are clusters of 

 pedunculated papillae, but histological examination alone reveals 

 whether these are conical or fungiform in type.

The tongue of Cercocelus cethiopicus. 



Lym'plioidj Follicles and Ducts. 



On the base of the tongue there is on each side a large cluster 

 of lymphoid nodules, and sevei-al large ones have orifices of ducts 

 or pits. The two masses are separated by the median glosso- 

 epiglottic fold. 



The Lateral Organs (text-fig. 32 & D). 



On each side of the tongue thei-e is a row of laminae and sulci. 

 The latter are short and wide, and the former are small and 

 rounded, so the organs look like rows of beads. The laminae are 

 smooth, furrowed, or crossed by a ridge, and are single or double 

 (text-fig. 32 0, n). 



The measurements, laminae, and sulci are shown as follows : —
