Circulatory apparatus: The vascular apparatus of Criodrilus is similar to that of Drilocrius, but the valvular apparatus is well developed and each heart is divided into about seven compartments; the latero-parietal vessels run beneath the coelotelium and are directly connected with both the dorsal and the subneural vessels; the latter runs within the coelomic space adhering tightly to the nerve cord.
