Show 510 PROF. ST.-GEORGE MIVART ON THE ALUROIDEA. [June 6, The Liver. The liver in Felis has the left lateral and right central lobes very large, the latter being divided by a deep cystic fissure, in which lies the gall-bladder, and the former being also somewhat divided by a fissure. The right lateral and left central lobes are each undivided and very small. The caudate lobe is of moderate size, about as large as the left central lobe. The Spigelian lobe is small (the smallest lobe), and is not divided by any fissure. The liver of Genetta tigrina is very like that of the Cat; but the left lateral lobe is quite undivided, save by a small shallow groove on its posterior (gastric) surface. The cystic fissure is less deep Liver of Genetta tigrina, its posterior (gastric) surface. c, caudal lobe; gb, gall-bladder; ha, hepatic artery; hd, hepatic duct; L C, left central lobe ; L L, left lateral lobe; p v, portal vein; i?

The caudate lobe has a very deep concavity, and is larger in proportion to its breadth. It runs uninterruptedly into the Spigelian lobe, which latter is a little larger relatively than in the Cat, and has a very deep groove (or fissure) running dorsad from its ventral margin, and dividing its proximal third from its distal two thirds. The diaphragmatic surface of the liver exhibits but a short cystic fissure. In Viverra civetta the right lateral and right central lobes appear nearly of equal size, as seen on the diaphragmatic aspect of the liver. |
