ANAITIS YATEI (Plate VIII.).—Fig. 29 (late Chione yatei) 
is a pale yellowish or brown shell, with a purple or slate-coloured 
patch round the hinge. The ridges on the outside, especially on 
the young shells, are thin and very high. As the shell attains 
its full size these ridges wear down. The old shells become thick 
and heavy, and are over two inches in width. It is found on 
exposed or ocean beaches in the North Island, and rarely in the 
South. The Maoris call it Pukauri. 
HALIOTIS IRIS (Plate IX.).—Fig. 1 is the Pawa or Papa 
of the Maori, and the Mutton fish of the colonist. The outside is 
brown, and the inside a dark metallic blue and green, with an 
iridescent play of yellow and other colours. It is found on rocks 
in the open sea or on exposed beaches, and is six or seven inches 
wide. 
HALIOTIS RUGOSO-PLICATA (Plate IX.).—Fig. 2 is 
about half the size of the Haliotis iris, and is known to the Maoris 
as the Pawa-rore or Koro-riwha. The outside is pinkish-brown, 
the interior being pale and highly iridescent. It is usually found 
with the Haliotis iris, but is not so common. 
Another Haliotis, named the Virginea, is much smaller and 
thinner than either of the above. The interior of this is like that 
of the Haliotis rugoso-plicata, but the exterior is variegated, and 
dotted and splashed with every conceivable colour. It is rare, 
and usually found on the sheltered side of small islands in the 
open sea. 
GLYCYMERIS LATICOSTATA (Plate IX.).—Fig. 3 (late 
Pectunculus laticostatus) is a very solid, reddish-brown shell, some- 
times (especially in the immature shells) splashed with chestnut 
and white. The six or eight teeth near the hinge on both valves 
are of even size and shape. It is usually found cast up on ocean 
beaches. The shell attains a length and breadth of three and 
a-half inches. The younger shells have ridges or ribs on the 
outside, but these wear off with age. The Maori name is Kuakua. 
GLYCYMERIS STRIATULARIS (Plate IX.).—Fig. 4 (late 
Pectunculus sfriatularis) is a small brownish shell, irregularly
