more complex structure than had at first been suspected. The 
body which had been projected from the capsule, and which had 
appeared in the recent zoophyte a simple filament with a spiral 
groove, was now seen to be composed of a delicate transparent 
tube marked with circular or spiral strie, and having within it 
a spiral filament which with rather distant coils wound through 
its entire length (fig. 7). 
Both sets of bodies now described are slowly but effectually 
dissolved by nitric acid without effervescence, appearing to be 
neither siliceous nor calcareous, but of a truly animal composition. 
That they are analogous to the lancet-bearing capsules discovered 
by Corda in Hydra,and whose existence I have myself been enabled 
to verify, there can I think be no doubt. Bodies strictly ana- 
logous, though differmg somewhat in detail, I have detected in 
three other genera of Helianthoid Zoophytes, namely Actinia, 
Anthea and Lucernaria, while Ehrenberg, Wagner, Erdl, Qua- 
trefages, Bailey and others have described similar organs in this 
and other families of Invertebrata. 
Tn attempting to assign a use to the bodies in question some 
difficulty is encountered ; perhaps the most tenable opinion is 
that generally held, namely, that they are in some way connected 
with the predaceous habits of the animal, and are most likely 
gifted with the power of inflicting envenomed wounds on the 
creatures which constitute its prey. | 
Corynactis viridis is a charming little animal, and by no means 
rare in the locality where I discovered it; the brilliancy of its 
colours and the great elegance of its tentacular crown when fully 
expanded render it eminently attractive ; hundreds may often be 
seen in a single pool, and few sights will be retained with greater 
pleasure by the naturalist than that presented by these little zoo- 
phytes as they spread abroad their green and rosy crowns among 
the many-tinted sea-weeds and plumy corals, cotenants of their 
rocky vases.

Sukkur, Upper Scinde, March 14th, 1846. 
Tux country about Kurrachee is very desolate, the immediate neigh- 
bourhood of the sea low and flat, the sandy soil bound together by 
the Ipomea Pes Capie, and on the muddy shores of the creek grow 
Rhizophora candelaria and Salicornia indica. The Rhizophora grows 
within water-mark, is like a tree in appearance and habit, but not 
above two feet high, and a bank of it looks like a miniature forest. 
The soil beyond the immediate limits of the beach is bare, and the
