torted fljell of that fpecies ; thefe diftortions appear to be 

 cccafioned by being fixed in the crevices of rocks, and arc 

 by no means uncommon on moft of our rocky fhores, where 

 all the gradations may be found.

From one of thefe fliells in which the animal was alive, we 



extra6led two very globular pearls of confiderable fize, but 



extremely foul. In another was a crab corrcfponding nearly 



to Caiicer pinnotheres , if not the fame. 



We are afllired by Mr. Laskey, that the fliell defcribed 

 lay Mr. Pennant from the cabinet of Doctor Walker, is 

 the fame as that found on the coaft of Devon, having exa- 

 mined thofe in the Do6lor's colleclion. It appears to be 

 known to the inhabitants of Barra, one of the Weftern 

 iflands, by the name of Feajkand, as the following note, ex- 

 tracted from a manufcript of Doctor Walker, appears to 

 evince. " No. 2268 Pinna borealis, it was brought up on 

 a fifliing hook, with the animal alive in it, 30 miles E. N. E. 

 off Sclietland. It is different I think from all the Liniucan 

 fpecies, and different alfo from all thofe figured by Gualtieri, 

 Sebj, and D'Argenville. It is the fame asthe Feajliand I 

 found in Barra."
