Notes on some Tasmanian chitons

Some time ago I received from Captain Beddome, of Hobart, several specimens of three species of Chitons, labelled respectively Chiton speciosus, Chiton australis, and Chiton liratus.
At the time they came to hand the South Australian forms were engaging my attention, and I at once saw that there must be some mistake in regard to those sent under the names of speciosus and liratus, as they could not be made to answer the original descriptions of those species, but the difficulty of satisfactorily identifying them by reference to the literature at my command compelled me to put them aside for the time being. A few months since some Chitons collected by Dr. Perks at Port Elliot, Encounter Bay, were submitted to me for examination, when I recognised that they were identical with the specimens sent to me by Captain Beddome as Chiton australis, Sowerby, and I so labelled them; further, I exhibited an example before the Royal Society of South Australia as an interesting addition to the molluscan fauna of this colony.
Having, however, since had the privilege of studying the exhaustive work of Mr. H. A. Pilsbry on the Polyplacophora (Chitons) as part of Tryon's Manual of Conchology, I found I had been too hasty, and had fallen into the too common snare of accepting a name under which a species is popularly known, and that, instead, the shell was the closely allied Chiton novaehollandiae, of Gray.
