New placoderm fishes from the Early Devonian Buchan Group, eastern Victoria.

Three new placoderms are described from the McLarty Member of the Murrindal Limestone (Early Devonian, Buchan Group). Murrindalaspis wallacei gen. et sp.nov. is a palaeacanthaspidoid characterized by having a high median dorsal crest and lacking a median ventral keel. M. bairdi sp.nov. differs from the type species in having a low median dorsal crest and a median ventral groove. Taemasosteus maclartiensis sp.nov. differs from the type species T. novaustrocambricus White in the shape of the posterior region of the nuchal plate, the presence of canals between the infranuchal pits and the posterior face of the nuchal plate, the shape of the paranuchal plate, and the development of the apronic lamina of the anterior lateral plate. The placoderms, Arenipiscis westolli Young, Errolosteus cf. E. goodradigbeensis Young, Wijdeaspis warrooensis Young, are recorded from the Buchan Group indicating close similarity to the ichthyofauna of the contemporaneous Murrumbidgee Group, New South Wales.-Author
