LIVER OF MAMMALIA. 487 fissures ; and these are still more marked in Otaria. Two hepato-cystic ducts entered the gall-bladder in the seal I Thecystic duct was joined by a small hepatic duct about half an inchfrom the gall-bladder; and a little lower down was joined by alarger hepatic duct, which was formed by the junction of twoother ducts, each of which was also formed by the union of twoducts, coining distinctly from four lobes of the liver. The ductuscommunis was one and a half inch long ; it was joined by the pan-creatic duct, as it terminated in a dilated sacculus within theduodenal coats. The inner surface of the gall-bladder is minutely rugous andvillous, the rugas becoming longitudinal at the cervix, and sub-siding in the duct. This character obtains in other Carnivora,in all species of which the alterative reservoir of the bile is pre-sent. In the Felines the valvular or impeding twist
