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
