PECTEN barbatus. 
TAB. CCXXXL 
Spec. Char. Orbicular, depressed, transversely 
striated ; rays 14, those upon one valve spinose ; 
spines long, acute, depressed ; ears nearly 
equal 
The spinose valve is the flattest; the striae upon it are 
sharp, and much elevated upon the sides of the rays,, 
from whence they curve into the bases of the spines, of 
which there are about five to each ray. The rays upon 
the other valve are convex, equal in width to the space 
between them, and crossed by less elevated striae than 
those upon the spinose valve. The sides of both valves, 
near the ears, are perpendicular and neatly pectinated. 
This remarkable Scallop is from the collection of Mr. 
Miller, who obtained it from the inferior Oolite of 
Dundry.
