 Common on the shores of Europe, burrowed in rocks and 



timber. 

 Shell about an inch and a quarter long, and four or five inches 

 broad, thin, brittle, and white ; the exterior surface is co- 

 vered with reticulated striae, which gradually become stronger 

 and more prickly towards the anterior end. Linnaeus, by his 

 references, appears to have confounded P. orientalis with 



* Pholas Chiloensis, and P. teredvla of Gmelin, are too obscure to be worth 

 retaining; and, as Mr. Wood observes, the latter is more like a portion of a 

 Teredo than a Pholas.
