Heremarked that many missing links will probably be found hereafter,and that nomenclature will be benefited thereby; thus, if Echino-thuria and Calveria really belong to the same genus, one of thesenames may be discarded. In support of this view he stated thatthe palaeozoic Euomphalus is identical, as regards the characters ofthe shell, with the recent Homalogyra. It is very desirable thatzoologists and palaeontologists should employ the same names. Quart. Journ. Geol . Soc .Vol .XXX. PI XXIV.
