, is familiar to residents on the seaside, both in
Australia and New Zealand, as it is a handsome shell, sometimes upwards
of four inches in length. The colour varies a good deal, but is usually
pinkish-white or pale chestnut, the wavy spots arranged in bands round
the shell being usually dark brown. Sometimes the shell is nearly white.
After heavy gales numbers are washed up on ocean beaches from the sandy
banks on which they live.

~SEMI-CASSIS LABIATA~ (Plate V.).--Fig. 6 (late Cassis achatina) is a
smaller and narrower shell than the former, and somewhat rare. The dark
markings are splashed, and not arranged in bands, thereby giving the
shell a mottled appearance. The interior is brown or purplish.

~LOTORIUM CORNUTUM~ (Plate V.).--Fig. 7 is a bright reddish-yellow shell,
covered with a very long epidermis, which makes the shell appear more
than double its real size. I have found a dozen or more of them on the
ocean beaches in the Bay of Plenty. They were all dead shells, about one
and a-half inches long, and the epidermis was wanting. The uneven,
blunt-pointed lumps, with which this shell is covered, make it easily
recognised. I have not heard of its being found anywhere in New Zealand,
except in the Bay of Plenty, but it is fairly common in Sydney.

~CALLIOSTOMA TIGRIS~ (Plate VI.).--Fig. 1 (late Zizyphinus tigris) is a
whitish shell, striped or dotted in rows with red. Although sometimes
over two inches across, the shell is thin and light. Its glistening
interior, and shapely lines, make it one of our most handsome shells.
These shells are sometimes found at low water mark, under and amongst
rocks in harbours, as well as amongst kelp in the surf. When once a
rock, or small patch of rocks, frequented by them is found, subsequent
visits in the spring or early summer will nearly always be successful.
It is common to both Islands. During the hot weather of summer, they
apparently move to below low-water mark, and remain there in the deeper
water until the winter. I obtained a considerable number of excellent
specimens from a strip of rocks near the water tank at the entrance to
Tauranga Harbour, but never found them except in spring or early summer.
The Maori name is Mata-ngo-ngore, which name is also used for the
Cantharidus family, on Plate VII.

~CALLIOSTOMA SELECTUM~ (Plate VI.).--Fig. 2 (late Zizyphinus cunninghamii)
is about the same width, but not the same height as the Tigris. The
colour is white, with pal
