numbers, but
the live ones are rare. The Maoris call this shell Hohehohe or Ku waru
or Peraro. The name Hohehohe is also given to the Panopea (Plate VIII.,
Fig. 3).

~TELLINA DISCULUS~ (Plate VIII.).--Fig. 20 is a clean smooth
yellowish-white shell, with a bright yellow centre, the interior being
the same colour as the exterior. Its length is 1-1/2 inches, and it is
found only in the North Island.

~TELLINA ALBA~ (Plate VIII.).--Fig. 21 is a very thin, flat, nearly
transparent, glistening white shell, the interior being the same colour.
Its length is 2-1/2 inches, and it is found on sandy ocean beaches in
both Islands. The native name for this shell is Hohehohe, which name is
also used for the Tellina glabrella.

~TELLINA STRANGEI~ (Plate VIII.).--Fig. 22 (late Tellina subovata) is a
whitish shell, similar to the Tellina alba, but more globose. It is
under an inch long.

~MESODESMA VENTRICOSA~ (Plate VIII.).--Fig. 23 (late Paphia ventricosa) is
an opaque white, solid, smooth shell, found in the North Island,
especially on the ocean beach near Kaipara. It is one of the many useful
food molluscs we have. In the Kaipara district the natives take horses
and ploughs on to the beach, and plough up the Mesodesma ventricosa like
potatoes. Under the native name of Toheroa, a factory at Dargaville
preserves these bivalves in tins. The specimen photographed was only a
half-grown shell. In the Bay of Plenty I have found this shell seven
inches long and extremely solid and heavy, and I am inclined to think
from the shape and structure of the valve that the Bay of Plenty
Mesodesma is different from the Ventricosa; but I never secured a live
one while in Tauranga.

~MESODESMA NOVAE-ZELANDIAE~ (Plate VIII.)--Fig. 25 (late Paphia
novae-zelandiae) is the common oval Pipi, or Kokota, of the Maoris. This
whitish shell, covered with a thin, horny epidermis, is sometimes 2-1/2
inches long. It is found in both the North and South Islands on sandy
banks in harbours and in tidal rivers.

~ATACTODEA SUBTRIANGULATA~ (Plate VIII.).--Fig. 24 (late Paphia spissa) is
a white shell, found in considerable quantities on sandy ocean beaches
at half-tide mark. When the tide is flowing it is a very common sight to
see great numbers of these bivalves washed up by the surf from their
beds, and it is very interesting to watch the speed with which they can
bury themselves again. They attain a length of about two inches, and are
known to the Maoris as T
