DR. C. F. SONNTAG ON THE ANATOMY 



The Circumvallate Papillae. 

 In specimen No. J. 357.1 there are four papilla? arranged in the 

 Y-formation. These are so disposed that there is a right lateral 

 papilla, a left lateral papilla, and two mesial papillae — anterior 

 and posterior. All are small in size. 



Text-figure 8.

The tongue of Hylobates lar. 



Two forms are shown, with dorsum (upper row) and inferior surface (middle row). 

 The figures R and L are lateral organs of the figure on the right hand, and 

 the unmarked lateral organ belongs to the left one. 



The lateral papilla? are oval and subdivided into two by fissures, 

 and the Valiums and fossa? are not very obvious.
