This is a very fingular fpecies: it’s length is about an inch; it’s breadth, in the 
largeft part, full as much, and it’s head or fummit pointed, but ornamented with a 
pair of large and fair ears, very nearly equal in fize : the verge, at the oppofite extre¬ 
mity, is rounded, and is even not finuated as in mod of the other fpecies: there are 
on the furface about fix ribs ; they are very broad, deprefted, and Hand at fmall di- 
ftances, and both thefe and the intermediate fpaces are ftriated in a very elegant 
manner: the colour of the whole fhell is a brownifh-yellow, fometimes a little varie¬ 
gated with a fainter yellow or with white, but this very rarely. 
It is found on the fhores of feveral parts of the Mediterranean, and makes a very 
lingular ftgure in the cabinets of our colledors.

This is the mo ft lingular of all the Pedens: it is about two inches and a half in 
diameter, and is nearly round ; the edges are every-where even, not at all indented or

valves are but little elevated, and there is not, on either of them, the leaft appearance 
of thofe ribs, which are almoft univerfal to the other fpecies of this genus: the fhell 
is extreamly thin, light, and brittle, and is of a pale brown colour j it’s whole furface 
is elegantly ftriated, but the ftrite do not run longitudinally as in the other Pedens, but 
tranfverfely, or in fomewhat rounded lines, beginning near the head where they are 
leaft: diftind, and continued in larger circles to the bottom of the fhell.
