On some Tasmanian Trochidae

Abstract

In the Proceedings for 1877 this Society did me the honor to publish in its pages a Census of the Marine Shells of the Tasmanian coasts. In that list I discussed some of the claims of certain species, but a great many questions connected with the classification I was obliged to leave untouched. I now propose to deal with the names of some of the Trochidae, and the validity of certain genera as regards those Tasmanian species which are included in them. It will be observed that in many cases I have remarked in the Census that I did not consider certain genera as very reliable. I do not know any family to which this is so applicable as to the Trochidae, and for the present I shall confine my remarks to them.
