Histological observation on the liver and kidney of Annamemys annamensis was made by paraffin section and microphotograph technique. The results show that the liver is separated into three leaves. The connective tissue is little and the borderline of hepatic lobule is mistiness in liver. The liver is composed of countless hepatic lobules and the borderline of hepatic lobules is mistiness. The liver cells are polygonal gland epithelia. The nucleus of cell are round and lay in the center. The bile ductules radiate along the hepatic cords and are connected to acerose microtubule. The kidney is composed of renal corpuscle. neck segment, proximal tubule, middle segment, distal tubule and collecting tubule. The renal corpuscle is composed of glomerulus and renal capsule. Structure of maculae densa is observed around renal corpuscle, but no medullary loop is discovered. The glomerulus is composed of coiling capillaries. The renal tubule starts and ends from renal capsule and is made up of inside and outside walls. The inside wall sticks to the capillaries of glomerulus and the outside wall is composed of simple squamous epithelia.
