Cochlea pro funde fafciata, ore utrinque bidentato. 
The deeply fafciated Cochlea , with the mouth bidentated each way, 
This is a very elegant fpecies; it grows to about an inch in diameter, and is 
nearly round ; the clavicle is very fmall and depreffed : the whole outer furface of the 
fhell is formed into elevated broad fafciae, which are only feparated by narrow furrows, 
and run all the way parallel to one another : the colour is a pale whitifh-grey, variegat¬ 
ed in a beautiful manner with black : the infide of the (hell is white and pearly ; the 
mouth is of an irregularly femicircular figure: the anterior lip is broad, thick, and pro¬ 
minent, and the pofterior, or tranfverfe, one is very broad; each of them has two den- 
ticulations in the form of teeth, which are fometimes white, like the reft of the inner 
furface of the fhell, but often red, and as it were bloody. 
It is very frequent in the Eaft Indies, and has been met with on fome of the Euro¬ 
pean coafts. 
Cochlea elevata fpinofa. 
The elevated\ prickly Cochlea, 
This is a fmall, but a very fingular and elegant, fpecies: it’s length, or height, is about 
three quarters of an inch ; it’s diameter hardly half an inch ; it confifts of four turns, and 
it’s furface is formed into perpendicular, obtufe ridges, with fmall hollowed fpaces be¬ 
tween them ; round the larger turns, it has two feries of long and flender fpines, very 
fharp-pointed; the outfide of the fhell is beautifully variegated with a deep reddifh- 
brown, and a paler colour approaching to white. 
It is a Chinefe fhell; we have it in fome of our cabinets. 
Cochlea elata fufco-nebulata. ClOUtlrtl 
The elated Cochlea , clouded with brown, 
This is about an inch and a half in height, or length, and an inch in diameter: it con¬ 
fifts of five fpiral turns, and the extremity of the clavicle is fmall and obtufe : the whole 
external furface is fmooth ; no riling, nor any fafcire or protuberances, appear on it, nor 
even fo much as a ftreak of any kind : the ground colour is a pale brown, and the varie¬ 
gations, which are difpofed irregularly in fmall clouded fpots, are of a very dark brown : 
the mouth is large, and of a tolerably regular figure of the femicircular kind ; that and 
the whole infide of the fhell is filvery.
