476 DR. R. O. CUNNINGHAM ON THE REPTILES, 
17. Fusus GEVERSIANUS, Pall. 
This species is one of the commonest mollusks in the Strait of Magellan, abounding 
from the eastern entrance to Port Famine. 'To the west of Port Famine it is not so 
abundant, being partially replaced by the following species. 1t also occurs at the Falk- 
land Islands. 
18. Fusus LACINIATUS, Mart. 
This elegant species is abundant in the western part of the Strait, and also occurs in . 
the channels on the west coast of Patagonia. I never met with it to the east of Punta 
Arenas. It inhabits rather shallow water; and specimens were taken in Tilly Bay, 
Carlos III. Island, feeding on Mytilus chilensis. Like the common Purpura lapillus of 
our shores, the animal bores a small circular hole in the valve of the mussel, and then 
sucks out the soft parts of the body. 
19. Fusus MURICIFORMIS, King. 
This small species is very common in the Strait of Magellan. 
20. Fusus LIRATUS, Couth. 
Specimens of this species were procured at Port Stanley, Falkland Islands. 
21. Fusus PHILIPPIANUS, D'Orb. 
This species was obtained in one or two localities on 2 Fuegian coast, in the eastern 
part of the Strait of Magellan. 
22. Fusus (CHRYSODOMUS) ALTERNATUS, Phil. 
Specimens were dredged in Herradura Bay, in November 1868. 
BUccINIDA. 
23. APOLLON Kriwair, D'Orb. 
Dead shells of this species were dredged in Sholl Bay, at the southern extremity of 
Smyth's Channel. 
24. BULLIA SQUALIDA, King. 
Numbers of dead shells of this species were met with in Gregory Bay and other loca- 
lities in the eastern part of the Strait of Magellan; but I never succeeded in obtaining 
live specimens. 
25. Nassa Gays, Hien. 
Two rather distinet varieties of this species were obtained, one of an elongated form, 
at Port Otway (Cape Tres do and the other of the ordinary shape, in rock-pools 
in the Bay of Coquimbo.
