TASMANIA** DEVIL. 



Right Lateral Lobe. — Though this is described as a 

 separate lobe it really, as stated, is joined with the cystic 

 lobe — the whole forming a large right lobe. It is charac- 

 terized by its Assuring' and lobulation, which is even met 

 with on the renal surface. It is concave below for the 

 reception of the right kidney, and is prolonged external 

 to the kidney as a pointed extremity. Projecting on this 

 right lobe, and forming the ventral part of the concavity 

 for the upper pole of the kidney is the well defined lobus 

 caudatus, 3 cm. laterally, and 2 cm. dorso-ventrallv. This 

 is prolonged to the left as a somewhat flattened, though 

 pointed, lobus spigelii, which is traced ventral to the left 

 lobe. Between the caudate and spigelian lobes is a well 

 defined depression, and here, passing down between the 

 two, we have the vein, artery, and duct. Dorsal to the 

 inner extremity of the lobus caudatus is the entrance of 

 the inf. v. cava. As regards its hepatic relationship it is 

 hidden — only the entrance and exit, as described, being- 

 visible. The hepatic relationship of the vein measures 

 4 cm. 



No. 2. — Here on the diaphragmatic aspect the three 

 lobes of the liver, viz., right and left lateral, and mesial 

 or cystic, are distinct. Large variety. Three-lobed liver. 



Left Lateral Lobe. — This not only forms in the left 

 hypochrondrium the left margin, but also takes place in 

 the formation of the ventral margin, and ma} 7 extend in 

 the epigastric region to the right of the ensiform cartilage. 

 It is smooth, not being characterized by Assuring and 

 lobulation, and presents a projection on the inner side, 

 which forms part of the left boundary of the portal in- 

 terval, or fissure. It tends to occlude the greater portion 

 of the left part of the cystic lobe, and dorsal to the pro- 

 jection presents on the inner side a concavity for the 

 oesophagus. It is separated from the left part of the 

 cvstic lobe by the well defined left lateral fissure, and is 

 concave ventrally for the fundus of the stomach.
