CYLINDRUS. 
T H E Cylindrus is a Ample fliell, without a hinge, formed of one continued 
piece, and of a figure approaching to a cylinder : when it departs any thing from 
that, it is not large# at the head as the voluta is, but, toward the middle, the mouth 
is always long and narrow. / 
The animal inhabiting the Cylindrus is a limax. 
The clavicle in this {hell is, in fome fpecies, continuous with the body, in others it 
is divided from it by a kind of circle, and in fome it is coronated : the columella is 
fmooth in mo#, but in fome it is rough.

This is a large and elegant {hell: it is three inches and a haif in length, and near 
two and a quarter in diameter* and is nearly of the fame thicknefs in the whole body, 
only diminifiiing a little at the two extremities 1 the head is denticulated or coronated, 
but the denticulations are not fharp j the clavicle has four or five turns, and is termina¬ 
ted by a point: the ground colour of the fhell is a filvery white, and it is beautifully 
variegated with a bright brown, in fine irregular lines, clouds, and blotches; the 
whole furface of the fhell has a naturally fine polifii, and the ground-work and varie¬ 
gations have much the appearance of a fine brocade. 
We have it from the coafts of the warmer parts of America, and fometimes from 
thofe of Africa.

“The thick, white Cylindrus , variegated with blue 
and brown . 
This is a very beautiful and a very fcarce fhell: it is about three inches long, and 
two in diameter, but it is not fo regularly of a cylindric figure as fome of the others ; 
it is large# a little below the head, and thence grows gradually fmaller to the other 
extremity : the clavicle has ten or twelve volutions, but it is not very much elated, and 
terminates in an obtufe point: the ground colour of the fhell is whitifh, but the varie¬ 
gations, which are partly blue, and partly brown, are very beautifully thrown into 
irregular clouds, and with larger and fmaller fpots. 
It is a native of the Eaft Indies, and is but feldom brought over to us, efpecially in 
any tolerable ftate of perfection, and brightnefs of colour.

fyell. 
This is about two inches and a half in length, and an inch and a quarter in thick¬ 
nefs ; it is pretty regularly of a cylindric figure, and the clavicle is fhort and obtufely 
pointed : the colour of the fhell is a pale whitifh, with a caft of red, and it is all 
over clouded with variegations of a deeper red, approaching to purple: this purple, 
though not the ground colour, takes up the far greater part of the furface, and the 
white, which is the true ground colour, is fcarce any where feen without a greater or 
lefler tinge of the red in it: the purple is, in mo# parts of the fhell, formed into irre¬ 
gularly longitudinal and dentated lines. 
It is brought to us from the coa#s of South America.
