T | ^ H E fhell of the Balanus is of an oblong figure, approaching to that of an acorn, 
X open at the mouth or top, and compofed of feveral portions or valves, from fix 
to twelve in number, not moveable or loofe as in the other bivalve or multivalve fhells, 
but fixed to one another by an intermediate fubflance. 
The animal which inhabits this fhell is a Triton, a genus defcribed before in it’s 
place. 
Balanus major Jlriatus ore ampliore. 
The great , ftriated Balanus, with a large mouth. 
This is the largeft of all the Balani, and that in which the figure, dru&ure, and 
parts of the fhell and it’s inclofed animal may be the mod didindly feen: it is about 
an inch and half in height, and more than an inch in diameter in the larged part, 
which is a little lower than the middle : the bafe is broad, and is firmly affixed to 
fome folid fubdance j the top is nearly of equal diameter with the bafe, and is wide 
open ; the mouth is not regularly round, nor is it’s verge even, fome part of it fland- 
ing up irregularly above the red : the fhell is compofed of twelve valves or lamina, of 
a flender and fomewhat pyramidal figure: they touch one another or join at the 
bafe, but, as they grow narrower toward the top, they recede from each other, and at 
the very fummit are confiderably didant: they are not loofe or moveable at the ani¬ 
mal's pleafure, but are united firmly to one another, by an intermediate, fhelly matter, 
fomewhat thinner than themfelves, and of a paler colour: the valves or ribs of this 
fhell are driated longitudinally, and are of a brownifh-red : the intermediate fubdance 
is of a paler hue, with lefs of the brown in it, and is irregularly undulated in a tranf- 
verfe direction: the inner furface is of a whitifh colour, with an admixture of fiefh 
colour and blue. 
The included animal has an armature compofed of four pieces, of a triangular form 
at it’s head, and from the center of thefe there iflue the arms of the creature : thefe 
four pieces of armature ferve it at other times for the doling the aperture, at which 
foulnefles of various kinds would get in, to the great annoyance of the animal. 
It is frequent on the fhores of the Ead and Wed Indies, adhering to rocks, and to 
the fhells of the larger fhell-fifh ; fometimes to the bottoms of veflels that have lain 
ong in harbour: great numbers of them are ufually found affixed fide by fide to one 
another.
