Pass a seeker through the glottis to one of the lungs and slit it open with a pair of scissors. Examine the structure of the lung. 2. Remove the whole of the alimentary canal with the lungs, liver, pan- creas, and spleen, by cutting through the oesophagus and the large intestine before it joins the cloaca, and detaching it from the roof of the body cavity without injuring the kidneys and the reproductive

Draw the complete alimentary Entrance of Bile duct into Duodenum Cloacal aperture Fig. 8.—Alimentary Canal of Xenopus and Rana. Urinogenital System. Note the kidneys, two elongated, flattened, dark-red bodies lying one on each side of the vertebral column towards the posterior end of the abdo- minal cavity. From the outer edge of each kidney a ureter arises and runs backward, opening into the cloaca on the dorsal side, opposite the opening of the urinary bladder. [In the Frog the adrenal bodies may be seen on the ventral sides of the kidneys as small yellow patches.] 24.
