    Among 544 cattle with congenital cardiovascular anomalies, five cases (0.9%) had the right aortic arch. They were five cases (0.1%) in a series of 5144 cattle necropsied at the Miyazaki University. Case 1 was complete heterotaxia and its heart and great vessels showed a mirror image of the normal. The other four had the situs solitus of the atria and abdominal organs. In case 2 the left subclavian artery originating from the brachiocephalic trunk, passed across the dorsal aspect of the esophagus over to the left side and formed an incomplete vascular ring. In cases 3 and 4 the left subclavian artery originating from the brachiocephalic trunk, crossed ventral to the trachea. In case 5 the aberrant left subclavian artery arose as the last branch of the aortic arch and passed across the dorsal surface of the esophagus. Moreover the left ductus arteriosus in this case connected the bifurcation of the pulmonary trunk with the distal part of the aortic arch, and a complete vascular ring was formed around the esophagus and trachea.

    Twenty rabbit lungs were examined. The right and left bronchi give of four bronchiole systems, i.e. the dorsal, lateral, ventral and medial. The cranial lobe is formed by the first bronchiole of the dorsal bronchiole system. The middle lobe is formed by the first bronchiole of the lateral bronchiole system, and the accessory lobe is by the first bronchiole of the ventral bronchiole system. The remaining bronchioles of the four bronchiole systems constitute the caudal lobe. Accordingly, the right lung consists of the cranial, middle caudal and accessory lobes, and the left lung consists of a bi-lobed middle and caudal lobes. The right pulmonary artery runs across the ventral side of the right cranial lobe bronchiole. Then it runs across the dorsal side of the right middle lobe bronchiole. Thereafter, it runs along the dorso-lateral side of the right bronchus. During its course, it gives off arterial branches, running along the dorsal or lateral sides of the bronchioles. The left pulmonary artery runs across the dorsal side of the left middle lobe bronchiole. Then it runs the same course as in the right lung. The pulmonary veins mainly run the ventral or medial side of the bronchioles or between the bronchioles. Finally they enter the left atrium with large four veins.
