Kiister (1846). Young and fry : T. horridus and LLeliciella costellata, O. G. Costa. It will thus be" seen that this remarkable and widely dispersed shell has been placed in five different genera, to which must be added Craspedotus of Philippi (1847) and Danilia of Brusina (1864). It is true that Olivia was proposed by Bertolini in 1810 for a genus of Polygastrica; but there is no probability of any confusion arising on "that account, because these classes of the Invertebrata are so widely separated.
