    A REVISED CLASSIFICATION OF CYNODONTS (REPTILIA; THERAPSIDA)
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1972) Hopson, James A.; Kitching, James W.
    Cynodonts are very advanced mammal-like reptiles of the Permian-Triassic which are of special interest to evolutionists because they gave rise to the Class Mammalia during Middle or Late Triassic time. Cynodonts have been known from strata of Early Triassic age in South Africa for over one hundred years, and numerous specimens have been collected and described. In recent years the record of cynodonts has been extended into earlier and later time zones, not only in southern Africa but in East Africa, South America, Russia , China, and, most recently, in North America. Much of the material from outside of Africa has not yet been fully described.

    SOME MEGASPORES FROM SOUTH AFRICA AND AUSTRALIA
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1972) Dijkstra, S. J.
    Dr. Plumstead has sent a number of samples from South Africa to us for maceration of the spores from them and for an attempt to determine the horizons from the megaspores only. Other details were not given. In addition to these samples we had some from Australia, and it became very interesting to compare the spores from S. Africa with those from Australia or other Gondwana deposits in India or Brasil.
