LÖNNBERG, ANATOMY OF INDIAN TAPIR. 5 



as the figure proves (conf. fig 3). The fungiform papillse 



are much more numerous and occupy a much larger area of 



the upper surface of the toiigue in the Tapir than in the 



Horse. On the other hand there are in the latter animal 



several faj)ill(je fungiformes scattered on the lateral surfaces 



of the tongue where none such can be found in the Tapir. 



The jmjnllce vallatcB are very much 



larger and much more comphca- 



ted in the Horse as the central 



papilla within the wall is subdi- 



vided in a large number secon- 



dary papillae, while the central 



papilla of the Tapir is simple 



and more similar to the corre- 



sponding organ in the Ruminants. 



According to Garrod's de- 

 scription of the tongue of a 

 Sumatran Rhinoceros^ this must 

 differ still more from the same 

 organ of the Tapir. The Rino- 

 ceros is said to have numerous 

 pajnllce vallatce (33 on one, and 

 26 on the other side) arranged 

 in »two dusters». Still more 

 striking is Garrod's statement: 

 »The rest of the tongue is cove- 

 red uniformly with filiform pa- 

 pillae, among which no fungifor- 

 mes are to be seen.» 



On the lower side of the free 

 end of the tongue of the Tapir 

 there is mesially a cordlike pro- 

 minence (conf. fig 3), which measures about 4 mm. in thick- 

 ness, but gradually tapers to an inconspicuous seam at the 

 tip and likewise disappears posteriorly, so that it is not 

 continuous with frenidum lingucE. This ridge-like prominence 

 is formed by a thickening of the skin along the median hne. 



Underneath the skin just under frenulam linguce a tongue- 

 like body was found. It has a rounded end and is 174
