LIVER OF TASMANIAN DEVIL 



(SARCOPHILUS URSINUS.) 



Diaphragmatic Surface. — Viewed from this aspect, 

 the liver may present three main lobes or divisions, viz., 

 mesial or eystie, right lateral, and left lateral. In some 

 specimens, however, the right and cystic lobes form a 

 single lobe, so that the liver consists of two main divisions 

 only. 



Left Lateral Lobe is larger than the right lateral, and 

 usually projects well forward, forming part of the ventral 

 border of the liver. Occasionally it does not project so 

 far forwards, and practically the whole of the ventral 

 border is formed by the anterior edge of the mesial lobe. 

 This is specially noted in the two-lobed liver. In a well 

 defined case the left lobe measured 14 cm. from before 

 backwards, and 12 cm. laterally. In all cases this lobe is 

 well defined by a left lateral fissure — usually traced inter- 

 nally to the inf. v. cava — from the mesial or eystie lobe. 

 On the inner or right margin dorsally is the concavity for 

 the passage of the oesophagus. 



Mesial or ('//stir Lobe. — This presents a well marked 

 cleft for the gall bladder, and by this means two portions 

 may be distinguished, viz., right and left mesial, and either 

 of these may be the larger. Occasionally specimens may 

 show subdivisions of either right or left portions. Thus 

 in an adult male specimen I found the right and left por- 

 tions separated by the cleft and fissure for the gall blad- 

 der, and, in addition, two well defined lateral lobes were 

 noted (i.e., four cystic lobes in all), and these were sep- 

 arated by well defined fissures. On the right portion one
