~COCHLODESMA ANGASI~ (Plate VIII.).--Fig. 4 (late Anatina angasi) is a
very white, almost transparent, thin shell, three and a-half inches
long. One valve is nearly flat, and the shell gapes to a considerable
extent at the narrower end. It is found in the open sea in sand in the
North Island, Cook Strait, and Australia.

~CORBULA ZELANDICA~ (Plate VIII.).--Fig. 5 is a yellowish or pinkish-white
shell, with fine longitudinal lines on it. The interior is brownish, and
the shell over half an inch long. It is common in the North Island and
Australia.

~SAXICAVA ARCTICA~ (Plate VIII.).--Fig. 6 is a rough, distorted,
yellowish-grey shell, about three-quarters of an inch long. The interior
is whitish. It is usually found in the roots of kelp or in sponges, and
is obtained in both Islands.

~MYODORA STRIATA~ (Plate VIII.).--Fig. 7 is a whitish or greyish-white
shell, with fine longitudinal lines, the interior being pearly. It is
1-3/4 inches long. The right valve is rounded and the left valve flat.
It is found in harbours, as well as on ocean beaches. The flat valves
make excellent counters for card-players.

~MYODORA BOLTONI~ (Plate VIII.).--Fig. 8 is a smaller and narrower shell
than the Myodora striata, and the left valve is flat. In colour it is
similar to the Striata. It is seldom over half an inch long, and lives
on flat, sandy beaches. It is often found when sifting sand for small
shells through a fine meshed sieve.

~MACTRA DISCORS~ (Plate VIII.).--Fig. 9 is a large, rotund, greyish-white
shell, with a blackish-brown epidermis. It is over 3-1/2 inches across,
and is found on sandy ocean beaches all over New Zealand. The Maori name
is Kuhakuha.

~MACTRA AEQUILATERA~ (Plate VIII.).--Fig. 10 is a yellowish or white shell.
It generally has a bluish-purple patch round the hinge. It is found on
ocean beaches, and is over two inches long. The Maori name is
Kaikaikaroro, which is also used for the Struthiolaria (Plate IV.), and
Chione costata (Plate VIII.).

~STANDELLA OVATA~ (Plate VIII.).--Fig. 11 is a thin, brownish-white, and
somewhat wrinkled, shell over three inches long. The edge of the shell,
and sometimes the whole shell, is covered with a brownish epidermis, the
interior being yellowish. This shell is found all over New Zealand on
muddy beaches, and especially near mangrove bushes in Auckland Harbour.
