In this paper a new species of the Tapinocephalid Dinocephalian Struthiocephalus (S. kitchingi) is described, based on a good skull without lower jaw, adding not only to our
knowledge of the structure of the skull of this genus, but also exhibiting more pronounced
features on the strength of which some idea may be formed regarding the mode of living
of the animal. This specimen differs appreciably from the known species, S. whaitsi, S.
rheederi, S. milleri, and S. akraalensis, but where some of the differences appear even to
transgress the generic boundary, it is considered that previous descriptions are not based on absolutely perfect material. Even the present specimen does not exhibit its structural detail so clearly that a wrong interpretation should be considered as excluded.
