to terrestrial plants. Two species in particular, 
named from this resemblance Sargassum aquifolium 
and S. tlcifolium, so closely imitate our common 
holly in their branches, berries, and twisted spinous 
| leaves, as to induce a belief, at the first glance, that 
they are no other than sprigs of that familiar plant. 
| Another species, found in the same locality, is called 
8. Tasxifolium, from its likeness to the yew. The 
lformer are highly interesting on another account: 
they afford a’remarkable illustration of the fact, 
that the seed-receptacles of some sea-plants are 
metamorphosed after the discharge of their seeds into 
leaves and air-vessels. Few would suspect that the 
round air-cells, that look like green berries, or the 
curled and thorny leaves, were alike the slender pro- 
.cesses containing the seed, only in another stage of 
development; yet specimens are often found in 
which the process is actually going on, both the one 
and the other being but partially transformed. The 
pores with which the surface of the leaves are stud- 
ded, are but the orifices through which the seeds 
escaped. 
| As we approach the Cape of Good Hope, the sea- 
birds peculiar to high latitudes again appear, and 
the sea and air are enlivened by myriads of gulls, 
terns, petrels, frigate-birds, and albatrosses. But 
among them we have yet to notice one pre-eminent 
among them, a master-fisher, which, for its powers 
of consuming the finny prey, is perhaps unrivalled. 
It is the Pelican (Pelicanus onocrotalus), which 
abounds all around the shores of the Indian Ocean, 
ranging to the distance of several hundred miles
