The Short-beaked Purpura, with fix feries of laeiniated (SJtUrftjfcs 
/pines. 
This is a fpecies eXtreamly different from the two former; it’s iength is about two 
inches, and it’s diameter, including the fpines, is an inch and a half: the body is of a 
figure approaching to oval; the clavicle is moderately long, and the roftrum fhort, or 
without that protended part, which gives fo remarkable an appearance to the others: 
there are, on the furface of this fhell, fix longitudinal feries of fpines or oblong protu¬ 
berances, fome of them more than a third of an inch in height, and all broad and jag¬ 
ged at the top: the body of the fhell is white, and thefe are black, either all over, or 
at leaft at the ends. 
The fhell is found in gre&t abundance on the fhores of the American iflands j but it 
frequently is bleached to a white all over, before we receive it.

"The fhort-beaked Purpura , with expanded fpines {l)tIL 
ranged in three feries . 
This is three inches long, and, including the fpines, is nearly as much in diameter i 
the body is large at the head, and gradually diminifhes thence in diameter, fo as to ap¬ 
proach toward a conic figure: the clavicle is moderately long, and has about fix volu¬ 
tions ; the whole furface of the fhell is deeply furrowed in a tranfverfe direction, and 
is ornamented with three feries or rows of fpinofe protuberances: thefe are from half 
an inch to a third of an inch in length, and are half as broad as they are long ; they 
are longitudinally furrowed on their furface, and are broad at their extremities and hol¬ 
low : the general colour of this fhell is a dirty whitifh. 
We have it from the fhores of the American iflands, and from the Mediterranean.

of the fhell is armed with a number of fhort and not very thick fpines $ they are of 
a conic figure, and are fome of them hooked 5 they ftand in eight or ten rows, and 
are continued to the roftrum, and, though with lefs regularity in the difpofition, to 
the clavicle : the fhell is of a whitifh colour, and, when quite in perfection, the tips 
of the fpines, and fome of them entirely are black : this colour foon bitches away, 
as the fhell lies on the fhores $ and, confequently, the moft of what we have are alto¬ 
gether white.
