THE LIVER OF BANDICOOT. 



(PERAMELIDAE.) 



Through the kindness of Professor J. P. Hill I was 

 presented with a female N.S.W. Bandicoot. The liver is 

 characterized by its resemblance to that of Trichosurus. 

 When examined from the diaphragmatic surface a well 

 defined separation into three primary divisions is seen, 

 viz., right lateral, left lateral, and mesial or cystic. These 

 are separated by well defined and complete right and left 

 lateral fissures. Apart from the exit at the junction of 

 the three divisions dorsally, the inf. v. cava is not seen in 

 its hepatic relationship. Three portions of the mesial 

 or cystic division, whose lateral measurement is 6 cm., 

 are defined, viz., right and left mesial, and intermediate. 

 The (smallest) left, and intermediate are separated by a 

 complete fissure — mesial, or cystic fissure — not, however, 

 extending as far dorsally, as the inf. v. cava — 1.25 cm., 

 intervening. Between the right and intermediate por- 

 tions of the cystic is a well defined gap for the gall blad- 

 der, which is seen on this aspect, 2.5 cm. long, and 1 cm. 

 laterally. The gap is not prolonged dorsally as a fissure. 

 Between the mesial or cystic fissure and the exit of the 

 vena cava is the attachment of the suspensoiy ligament. 



Visceral Surface. — The striking feature is the rela- 

 tively large size of the left lateral lobe, which occludes on 

 this aspect the intermediate and left cystic lobes, and its 

 edge may be traced on the right to the gall bladder. It 

 measures 3 cm. laterally, and 5 cm. dorso-ventrally, is
