Plate 31

FIG. 7. Multiple small perforations of valvula. The formation of ostium secundum normally starts with the appearance of small openings which later coalesce. Here such openings have appeared in a deﬁnitely abnormal location.

FIG. 8. Case similar to that shovm in Fig. 7. except that the openings are larger and more vddely distributed.

FIGS. 9. 10 and 11. Various combinations of marginal over resorption of the types shown in Figs. 1-6 with small multiple perforations similar to those shown in Figs. 7 and 8.

FIG. 12. Extreme resorption of valvula combined with abnormally large foramen ovale due to defective development of septum secundum. There is also in this heart unbalanced development of the ventricles. the left ventricle being very small, correlated probably with a defective puhnonary circuit as indicated by the marked stenosis of the pulmonary veins.
