Balanus fufcus ore ampliffimo campanulatus. 
The bell-fafoioned , very large-mouthed Balanus . 
This is a very Angular fpecies; it is ufually found in vaft clutters or congeries, fixed 
to one another at the tops, and forming a kind of reticulated furface in the whole, 
with large cavities underneath, between the bodies of the feveral individuals, which 
ferve as a happy recefs for the habitation of fea- worms of many kinds: the {hell is 
narrowett at the bafe, where it is affixed to fome folid body, and thence becomes 
gradually wider to the very top, where it is broad, open, and as it were bent a little 
down at the verge, fo as to exhibit, in the whole, fome refemblance of the figure of 
a bell: it is compofed of eight firm and hard portions, of a conic form, very dittant 
at their fummits, but conneded by a firm, fhelly fubftance, fomewhat thinner than 
their own : the colour of the whole is a browniffi-grey; the ribs more grey, and the 
intermediate matter more brown. 
We have large clutters of this fpecies fometimes from the American iflands, affixed 
to wood that has lain long under water j but they ufually come to us impeded and 
injured by the carriage. 
Balanus humilis ore amplo . 
The low Balanus 3 with a large mouth . 
This is about three quarters of an inch high, and more than half an inch in dia¬ 
meter j it ufually is found in large clutters, and the feveral individuals that form thefe 
are fo clofely conneded, that their inner furface is much more confpicuous than the 
outer: this is of a pale whitifh-grey, with an admixture of brown, and a flight tinge 
of red ; the feveral variegating colours are feen much more diflindly in fome parts, than 
in others. When the clutter is broken, and a Angle ffiell examined, it’s outer furface 
ffiews that it is compofed of fix parts or valves, conneded together by an intermediate, 
firm, fhelly fubftance : the valves or ribs are thick, ftriated, and of a pale red, with 
an admixture of grey and of brown : the intermediate matter of the fhell is of a yet 
paler red, with nothing of the brown in it: the largeft part of the fhell is near the 
bafe; the verge is a little contraded from this greateft diameter, but is ftill very large : 
the whole fhell has fomewhat of the appearance of a drinking cup, and has been thence 
Called the Chalice or Cup-fhell. 
~ It is not uncommon on the rocks and harder fea plants about the American ffiores. 
Balanus ellipticus grifeo ruhefcens , ore angujliore . 
The narrow-mouthed elliptic , greyijh-red Balanus . 
This is an extreamly elegant fpecies; it ufually grows in clutters of twenty, or 
more, together, and has a very Angular and pretty appearance: they do not all ftand 
upright, as in moft of the other fpecies, but are very clofe at the bafe, and more di¬ 
ttant toward the top, fo that they ufually form a clutter of a haemifpheric figure, of 
which the extream ones are confequenfiy in an inclined, and fometimes almbft in an 
horizontal, diredion : the Angle ffiell, feparated from the clutter, is about half an inch 
long, and nearly a third of an inch in diameter : it’s thicknefs is nearly equal all the 
way, but at the bafe it is fomewhat narrower than elfewhere, and the top is contraded, 
and the edges are drawn inward, fo as to leave but a fmall opening by way of mouth : 
the ffiell is compofed of twelve valves or portions, which are conneded indeed by an 
intermediate fubftance, as in the others; but they ftand fo clofe all the way, that the in¬ 
termediate fubftance is very little, and, the valves being more elevated, it fcarce appears 
at all: the valves are all deeply ftriated, and the colour is a dulky grey, with a confider- 
able admixture of reddiffi in it. 
We have this fpecies from the Eaft Indies, and from fome parts of America.
