This is a very beautiful fhell, and in it’s general fihape differs extreamly from the 
two preceding; it confifts of five fpiral turns, but it is perfectly flat, the clavicle not 
at all elated, but the point is funk lower than any other part of the {hell, in Confe- 
quence of it’s being more flender : the diameter of this (hell is about two inches and a 
half, and it’s thicknefs in the largeft part not more than half an inch : it’s mouth is 
round, and the {hell is there largeft, and goes from thence gradually tapering all the 
way to the central point •, the furface is fmooth, or at the utmoft has only the appear¬ 
ance of a few obliterated fafcias; the colour is entirely white, except that the eye of 
the volute is brown. 
It has fomething of the external figure of the Cornua Ammonis, which we find 
foftile, but their cavity is divided by cells in the manner of the nautilus ; this is entire, 
fo that it is quite of another genus.
