an organ in the Tapir. The statement of the two French 

 authors quoted must, however, appear rather suspicious as 

 it is made to comprise the Horse, as well, although the fa- 

 pillce foliatce of the latter animal are very well developed. 

 The present specimen proves that this is the case in the Tapir 

 as well. The papillce foliatce are to be found in the Indian 

 Tapir in the typical situation, viz. laterally at the base of 

 the tongue just behind the jMpillce vallatce (conf. fig. 2). 

 Their appearance is also quite typical and they measure about 

 15 mm. in length and 12 mm. in breadth. Parker has re-

corded almost the same measurement viz. »about half an inch 

 long». 



The whole tongue of the Indian Tapir is soft, even in 

 the centre of the middle third where no papillce fungiformes 

 are developed. There is thus no »Zungenriickenknorpel» as 

 that of the Horse and which, according to Ellenberger and 

 Baum, in that animal extends över a surface of 12—16 cm. 

 and attains a thickness of »2 — 3 — 4 mm».^ 



If the tongue of the Tapir is compared to that of a 

 Horse several other discrepancies reveal themselves as well. 

 With regard to the shape the former is not narrcwed at the 

 middle and widened again at the broad and squarely roun- 

 ded fore-end as that of the Horse, but has parallel sides 

 which at the end finally curve together to meet in a point
