mm. broad and about 7 mm. thick. From its lower side pro- 

 jects ventrally something like a septum which is thicker at its 

 connection with the body mentioned, but tlien gets thinner as 

 it extends backwards and downwards. This body consists 

 of fat, and there is perhaps nothing peculiar with it 

 except its rather regular shape and situation which recalls 

 in mind the »Unterzunge» or subhngua of which it might 

 be a rudiment. Further researches and more material is, 

 however, desirable before any opinion can be expressed 

 about this. 



On either side of the base of the tongue from frenulum 

 linguce and backwards an irregular row of papillae and the 

 numerous openings of glandula suhlingiialis are seen. 



In one of his numerous and valuable contributions to 

 the mammahan anatomy Beddard^ has pointed out »the 

 close attachment of the lungs to the waJl of the chest-cavity» 

 in the Indian Tapir. »This attachment», he says, »was by 

 means of fine and multitudinous strands of a ghstening ap- 

 pearance precisely like a much subdivided mesentery, and 

 was very complete; so much so that it would be quite fair 

 to speak of the pleural cavity as practically non-existent in 

 that animal». I am able to fully confirm this statement 

 from my own observation on this specimen. The attach- 

 ment was, however, not stronger than that the lungs easily 

 could be loosened without injury. 



Both lungs of this specimen were three-lobed, not coun- 

 ting the azygous lobe. The apical lobe is comparatively 

 narrow and pointed, the middle lobe (1. cardiacus) broad 

 with squarely truncate margin. As this division of the lung 

 in three lobes has been observed by Owen^ before but not 

 by some other authors, it appears to be a variable charac- 

 teristic, and it is possible that the lobes become more fused 

 together at an advanced age so that they then more resem- 

 ble the same organ of the Rhinoceros and the Horse. 



The liver of the Indian Tapir has been described and even 

 figured before but as there appears to prevail some uncertainty 

 and different opinions with regard to the homologies of 

 different parts of this organ, it is necessary to give a new 

 figure (fig. 4) and renew the description. The lateral lobes
