Each lateral abdominal receives a cloacal vein () from the rectal region and a femoral vein () from the pelvic fin. Between the pelvic and the pectoral regions the lateral abdominals receive numerous tributaries from the thinner musculature of the body wall, which are not shown in figure 185. In the pectoral region it receives the brachial vein {, fig. 187) from the pectoral fin, the subscapular (), including the lateral cutaneous vein {, fig. 187), and the coracoid vein () from the ventral part of the girdle; the last-named vessel re- ceives the ventral cutaneous vein from the skin. As the subclavian vein, the lateral abdominal turns sharply upward and enters the duct of Cuvier {, fig. 187). VEINS OF SKIN
