(Bernard Price Institute for Palaeontological Research, 1953)
This paper describes a number of new specimens recently collected in Cynognathus zone beds, now in the collection of the Bernard Price Institute for Palaeontological Research. These specimens include two new genera and species, Cistecynodon parvus and Inusitatodon smithi. The former is related to the Galesauridae, but it may perhaps represent a new family of Cynodonts. The latter is a Gomphodont Cynodont. In addition a very perfect specimen of Bauria cynops is described and descriptions based on two other specimens affirm the validity of Broom's genus Cyclogomphodon. The paper also includes a short description of a specimen of Diademodon broomi.
