beak, to remove from this mass of flesh the shell which surmounts it 
in order to have a natural ready prepared food. We do not know 
in what localities they find them; probably it is in the islets and on 
the rocks washed by the waves, since in the whole circumference of 
King George’s Sound we never found one. Our solitary individual, 
although living, lacked the specific zonal band. It was especially on 
Garden Island that we collected so many of their shells. 
Natica plumb ea, Lamk. 1 King George’s Sound. 
Bulla bicincta , new sp. 2 — It inhabits Princess Royal Harbour 
in King George’s Sound. In this place we saw the greatest collection 
of Bullas of every species all together. 
Bulla australis ■ new sp. 3 — These shells can be collected by 
basketfulls in King George’s Sound. They delight in the fairly calm 
waters of Princess Royal Harbour. When the animal is dead its 
shell becomes detached and is preserved intact among the masses 
of fucus piled up by storms. 
Bulla brevis, new sp. 4 — Excessively common at King George’s 
Sound. 
Bulla arachis, new sp.,° King George’s Sound. 
Buccinum costatum , new sp.. King George’s Sound. 
Buccinum litiopa , Rang. — This species comes from the South- 
west coast of New Holland. 
Fusus australis , new sp., King George’s Sound. 
Triton leucostomum , Lamk, King George’s Sound. 
Folium perdrix, Lamk. 6 - — The real home of the Doliums is 
the little island of Dirk Hartog and Sharks Bay, on the west coast 
of New Holland. We explored this region in the voyage of the 
“ITanie,” with M. de Frevcinet, and nowhere else have we seen so 
many fragments of them, though we were unable to secure a single 
living individual. 
Voluta undulata , Lamk.'- — We found Vol/uta undulata on the 
coasts of New Holland, at Sharks Bay, and at King George’s 
Sound. 
C onus lute us, new sp. — This species was captured, with many 
others, in about 50 fathoms, at the entrance of King George’s 
Sound. 
Ceritkium leve, new sp. s — This Cerithium inhabits King George’s 
Sound. We met with them on one occasion to the number of 
a hundred collected together in a calm place, shut in by the mass 
of rocks which are at the left of the entrance to Princess Royal
