Article: Disphyllidae and Phacellophyllidae from the Devonian Garra Formation of New South Wales

As part of a revision of the rugose coral fauna of the Garra Formation of New South Wales, the families Disphyllidae and Phacellophyllidae are studied, particular note being taken of Schouppe's (1958) revision of this group. The arrangement of trabeculae and the dissepimental structure of the two families are discussed.New taxa described are: Mansuyphyllum bellense sp. nov., M. parvulum sp. nov., M. catombalense sp. nov., Paradisphyllum harundinetum gen. et sp. nov., and Hexagonaria approximans cribellum subsp. nov., in the family Disphyllidae; Peneckiella boreensis sp. nov., in the family Phacellophyllidae.Biostratigraphic subdivision of the Garra Formation, a folded and faulted complex of reef and detrital limestones, is not yet possible. It is deduced to be probably Emsian in age, possibly extending to early Couvinian.
