LIVER IN MACROPUS. 



(KANGAROOS AND WALLABIES,) 



Though certain minor differences may be noted the 

 following can be regarded as the type, as evidenced by 

 examination of Macropus Giganteus — ITalabatus — 

 Parryi, and smaller varieties, such as the Tasmanian 

 Wallaby. 



The liver is somewhat obliquely placed — passing 

 down to the right — and lies in the epigastrium and right 

 hypochondrium. 



Diaphragmatic Aspect. — The liver — both lateral and 

 cystic lobes — is closely attached dorsally by bands to the 

 tendinous portion of the diaphragm. The suspensory or 

 longitudinal ligament passes between the cystic lobe and 

 the diaphragm, and helps to separate the small left por- 

 tion from the main right portion of the cystic or mesial 

 lobe. It can be traced between the dorsal part of the 

 cleft for the gall bladder and the inf. v. cava, being short 

 where the cleft is prolonged dorsally as a fissure. In a 

 Macropus Parryi the longitudinal ligt. ran from the 

 middle of the left cystic and out from the gall bladder 

 fissure. 



Three distinct divisions of the liver are seen on this 

 aspect, viz., large left lateral lobe — small mesial, or cystic 

 -and right lateral, intermediate in size, between the two. 

 In addition dorsally the left lateral aspect of the spi- 

 gelian lobe is seen, somewhat triangular in shape — with a
