NATURAL HISTORY. 
sphere, and this is particularly the case with the terrestrial 
groups: some of them belong to genera which are only found 
in the warmer parts of the northern half of the world. The 
genus Struthiolaria, is peculiar to New Zealand. 
The following are a few of the most beautiful kinds:— 
Fam. Muricidce. — Putotara, (triton vnriegatum.) This beau¬ 
tiful shell is often nearly a foot long, and is used as a trumpet; 
it is only found at the extreme north of the Northern Island, 
but appears formerly to have been more generally diffused. 
Fam. Volutidce. —The ( voluta magnified) is only found near 
Cape Maria, Van Diemen, and the North Cape; it is the 
largest and finest volute found in New Zealand. Pupu kari 
kawa, is a large spotted volute. 
Fam. Trochidce. —This is a numerous family. Ngaruru —is 
a very large kind. This name is also given to the ( trochus 
imperialist) Miti miti is a small trochus. 
Fam. Haliotidce. — Pawa, the (haliotis iris,) or mutton fish. 
This beautiful shell is found of considerable size; it is used 
for the manufacture of fish hooks. The fish is both eaten raw 
and dried, by the natives : it is very tough. There are several 
varieties of this shell found in different parts of the islands. 
There is also a small land shell, nearly allied to the haliotis ; 
it is about an inch long, of an olive color, and pearly lustre 
inside. The slug on which it is found is of a dark chocolate 
color (haliotoidece, Wanganui ). 
Fam. Patellidce — Ngakapi, the limpet. Many varieties are 
found, some very large, others of a star form; some sessile, 
others pierced at the apex. 
Fam. Chitonidce. — Papa piko (a large chiton): this is also a 
numerous family. 
Fam. Helieidce.—Pupu rangi, (helix Bushyi), a large flattened 
shell, with a thick olive colored shining periostraca: the inside 
is blue. This fine shell is sometimes nearly three inches in diam¬ 
eter ; its habitation is the tops of lofty forest trees, from which 
it is shaken by storms ; the natives therefore call it the sludl 
of heaven. It is not found much south of Auckland in the 
North Island, but Sir G. Grey found a broken specimen in 
Massacre Bay, Middle Island. Bulimus hongi pupu harakeke,
