New genus in the holothurian family synaptidae, with a new species from Tasmania

Abstract

Late in 1964, one of us (D.L.P.) received from Professor V. V. Hickman in Tasmania a specimen of a new synaptid holothurian from that island. Professor Hickman had prepared permanent mounts of representative calcareous deposits of the specimen, and very kindly offered all of his material of the species to D.L.P. for inclusion in a report on the apodous holothurians of the Australian Museum which was then in preparation. Early in 1966 F.W.E.R. received from the Oslo Museum six specimens and a fragment of the same species. Quite by accident we discovered that we were in the process of describing this new species independently. This joint contribution comprises the sum total of our investigations.
