This is a large and beautiful fpecies ; it is at the bafe two inches and a half long„ 
and near two inches, broad at one extremity, whence it becomes gradually fmaller to 
the other, where it is alfo obtufe and rounded ; it’s height from the center of the bafe 
to the fummit is about an inch and a quarter ; the top is fomewhat depreffed, and 
{lands nearer the largeft end of the oval than the other : the rim is even, and the whole 
furface is fmooth; the colour is a dulky whitifh, elegantly marbled, and variegated 
with a deep and blackifh clouding. 
It is found adhering to the rocks on the fhores of fome of the warmer countries in 
Europe, but not on the Englifh coafl, fo far as has been yet obferved.

This is a tall fpecies; it’s mouth is rounded, and the verge fmooth and even ; it’s 
diameter is about an inch, and it’s height nearly as much : the outer furface of the {hell 
has no ridges, but has fome roughneffes difpofed irregularly all over it; it is bellied half 
way up, where it begins to form a roftrum or head ; this is fomewhat pointed, and 
bends down : the infide of the {hell is concamerated, and the diviiion terminated by a 
kind of point 3 it is not very elegantly coloured, but this ftrudture is lingular. 
We have it from the Ihores of fome of the American iflands.

This is of an oblong or irregularly elliptic figure at the bafe; it’s length at the 
mouth is about an inch and a quarter, it’s breadth hardly half an inch; both ends are 
nearly equal in breadth, and the verge is fomewhat undulated : about half the aperture 
from one end, which may be efteemed the head, is covered by a thin cruft or {hell, 
connected to the end and along the fides, but irregularly notched at the verge; the 
height of the {hell is about half an inch; it’s roftrum or beak is {hort, and feems only 
a kind of button; it does not ftand in the center of the {hell, but juft at that end 
which we call the head, and near the verge of the {hell. The whole outer furface is 
rough and warty, and the inner fmooth, but neither very beautifully coloured. 
We have it on fome of the European fhores, 
Patella elliptica deprejfa vertice perforate . 
The elliptic and deprejfed Patella , with the top per¬ 
forated\ 
This is a large fpecies; it’s length at the bafe is near three inches; it’s diameter an 
inch an half at the largeft end, the other is a little fmaller, but ’tis fo little, as not to 
give it a title to the oval: the edge is fmooth and even ; the height of the {hell is a- 
bout an inch; it’s furface is almoft fmooth, but there are a number of longitudinal 
rays, and fome tranfverfe or circular ones alfo vifible on it: it’s colour is a duiky 
brown, and it is thicker and more robuft than many of the others: it’s top is not 
much elevated, and is as it were cut off; an aperture or hole appearing there, which 
is of an oblong figure, and feems to be formed of two round ones joined together 1 
the colour on the outfide is a duiky grey ; within it is whitifh, but with a few varie¬ 
gations. 
We have it from the Eaft Indies, and it is alfo common to fome of the warmer 
parts of Europe.
