The fpecies of this kind found in the Mediterranean are very large, and throw 

 out their ligaments like the American bank-oyfters ; but thele are eompofed of 

 (lender pliable fibres that fpin very readily, and are often made into ftockings, 

 gloves, cane-ilrings, and handkerchiefs, in all the adjacent countries. 



The Solena comes laft in this clafs, but is joined, like the foregoing, by a lon-
