The auricles receive the Ijlood direct from the gills; the ventricle forces it out through anterior and posterior aortffi (fig. 322), the latter lacking in many species. The excretory organs {organs of Bojanus) lie immediately below the pericardium (fig 322, n). Each consists in fresh water mussels of a dorsal smooth-walled chamber and a lower portion traversed by threads, Ijoth connected behind but separated elsewhere by a thin partition. The lower chamber is con- 21.
