Mr Neville Pledge, Curator of Fossils at the South Australian Museum, has informed us that the name Kimberia which we used to describe a new genus of arthrodire from Gogo (Dennis-Bryan & Miles, 1983) is preoccupied by a gastropod. This was described by Cotton & Woods (1935) as a subgenus of Turritella Lamarck, the type species being Turritella (Kimberia) kimberi. We therefore propose to substitute the name Kimberleyichthys gen. nov. for the arthrodire.
