Abstract

The paper records the characters of the genus Schizodus as defined by its type-species Axinus obscurus, and shows that King's reconstruction of the hinge-characters of Schizodus truncatus, regarded by him and many subsequent authors as the type-species, was inaccurate. The conclusion is reached that Protoschizodus de Koninck and the forgotten genus Prisconaia Conrad should be regarded as synonyms of Schizodus. A new generic name Eoschizodus is proposed for those smooth Myophoriidae of the Devonian, Carboniferous and Permian which differ from Schizodus in possessing the full number of hinge-teeth for the family, but which lack the conspicuous anterior myophorous buttresses of the Triassic Neoschizodus.
