The bulbo-auricular ridge thus forms the floor of this side of the auricular canal. The interventricular septum is attached to the right side of the cushion-septum and its foramen and the aperture of the bulbus lie side by side. It will also be remembered that the proximal portion of the bulbus is divided by a partition formed by right and left endocardial.
