parts, many veficles, of different fhapes, at certain fea- 
ions of the year, according to their different fpecies. 
Thefe veficles are protruded from the outward fkin 
or horny covering of thefe branched polypes, and 
from the inward or flefliy part arifes a larger polype ; 
one of which occupies each of thefe veficles. 
Thus a coralline full of veficles looks like a plant 
full of bloffoms, which, after they have arriv’d at 
their perfedt hate, fall off, with their capfules or ve- 
ficles, and become new-detach’d animals, to provide 
for themfelves; in the fame manner as the falling 
feeds produce other plants. 
Upon examining this coralline, we found, that the 
animals in the veficles were dead ; but, immediately 
afterwards, we had an opportunity of difcovering the 
veficulary polypes alive, in another coralline ; which 
are defcrib’d at fig. 6. in their natural fize, and at 
letter F as they appear’d magnified. This fpecies I 
have call’d the lea-oak coralline, from its being moft 
frequently found creeping on, and adhering to, the 
largeff fpecies of the quercus marinus , or fea-oak 
fucus. 
The veficles of the denticulated coralline, letter E y 
are defcrib’d as they appear’d full of fpines at the top, 
and clos’d up, as at letter G. 
The veficles of the fame fpecies are more fre- 
quently found as defcrib’d at 7, where the fpines are 
not unfolded: From this appearance, I have call’d it 
the pomegranate-flowering coralline, becaufe they 
nearly refemble the opening bloffom of the balauftine, 
er double flower of the pomegranate. 
The branches of this coralline are often obferv’d to 
end in vermicular tubuli, as at H , which are much
