Casting specimens of portal system and hepatic vein system in livers were made by injection of vinylite into the portal vein and postcava in 20 adult dogs. The author classificated the ramification of portal system and hepatic vein system. The results obtained were summerized as follows: 1. Portal system in livers were divided into left and right trunks. The left trunk subdivided into papillary process (caudate lobe,) left medial lobe, left lateral lobe, quadrate lobe and right medial lobe rami. The right trunk were subdivided into right lateral lobe and caudate proccss(caudate lobe.) 2. The lateral superior and medial inferior rami of portal system in left lateral lobe were subdivided 1 or 2 branches from left trunk. 3. The lateral superior ramus of portal system in left medial lobe did not appeared in 40% of the cases examined. 4. Portal system in quadrate lobe were subdivided 1-3 branches from left trunk, 5. Portol system in right medial lobe rami were relatively simple in ramification. 6. The lateral superior and medial inferior rami of portal system in right lateral lobe were subdivided 1 or 2 branches from right trunk. 7. Hepatic vein system of left lateral, left medial, quadrate and right medial lobe rami were originated from same ramus divided from the postcava in all cases. 8. Hepatic vein system of left and right rami in right medial lobe were divided from postcava.
