PURPURA. 
rii HE Purpura is a fimple fhell, having no hinge, formed of one continuous piece, 
and covered from the top to the bottom with fpines, with tubercles and um¬ 
bo’s ; with the mouth fmall, and approaching to a round figure, and with a fhort cla¬ 
vicle ; but ufually, with the other extremity, protended to a confiderable length. 
The Purpurae have, in general, been confounded with the murices, but very impro¬ 
perly, as the genera are fufficiently diftinguilhed, were it only by the fhape of the 
mouth, and as the fpecies under each are confiderably numerous. The murices are, 
in general, {hells of confiderable beauty, but the Purpurae are yet more lingular and 
elegant.

This is an extreamly elegant fhell3 it is about four inches in length, fometimes 
more 3 it’s body is fhort, of a figure approaching to oval, and ventricofe, and the 
clavicle is alfo fhort, but diftincft in it’s volutions: the roilrum or fnout, protended 
from the extremity of the mouth, is of nearly twice the length, of the reft of the 
{hell, and both this and the body are armed with four feries of very long fpines, fome 
of them more than an inch in length5 thefe are difpofed in regular, longitudinal fe¬ 
ries, and are {lender, pointed at the ends, and the greater part of them fomewhat crook¬ 
ed : the mouth is nearly round, but it’s opening is continued in the form of a flit up the 
roftrum of the {hell: there are fometimes regular feries of fhort fpines between thofe 
of the longer; fometimes there are only a few of them, and thofe difpofed with lefs 
order : the natural colour of the fhell is a tawny yellow, with an admixture of brown, 
but, with lying expofed to the fun and air upon the coaft, it bleaches into a whitifh 
hue : many of thofe we receive are thus altered in colour, and moft of them have the 
fpines more or lefs injured. A

furrounded with a narrow lip of a reddifh colour 5 the roftrum or fnout is continued 
from the extremity of this, and the opening runs all along it, in the form of a
