PECTEN annulatus. 
TAB. DXLII. —fig. 1. 
Spec. Char. Orbicular,, convex ; numerous, thin, 
erect, concentric laminae and fine longitudinal 
striae ornament the surface, passing over the 
large ears. 
Length about inches, which is rather more than the 
width ; the concentric laminae are about a line apart. Ex- 
cept that it is much less gibbose, it strongly resembles 
P. cinctus t. 371. 
Communicated by the Rev. T. O. Marsh, who col- 
lected it out of the Cornbrash Limestone at Felmersham. 
The anterior ear is probably reduced in size by fracture, 
as it is much injured. 
PECTEN Princeps. 
TAB. DXLIL— /g. 2. 
Spec. Char. Orbicular, compressed ; decorated 
with 90 rounded nearly equal radii surmount- 
ed with erect concave scales ; ears large, un- 
equal, squamose ; valves equal. 
Nearly orbicular, but rather wider than long : the 
scales upon the ribs are large and distant, chiefly upon 
the left valve ; but as there are rudiments upon the right 
also, that probably had them when the shell was entire. 
A handsome rare Crag fossil, found at Ramsholt. It 
ornaments the collection of the Rev. G. R. Leathes.
