Arctops willistoni
This is rather shadowy genus known from three skulls which might or might not belong to the same species, A. willistoni (?=A. watsoni) . Three additional but rather dubious species were also assigned to the genus: ?A. ferox, ?A. kitchingi, ?A. minor. It is quite possible that Arctops represent the adult form of the genus Scylacognathus and would therefore be a synonym of the latter (Gebauer, 2007).
