GENERAL REMARKS ON THE PENINSULA

attached to marine plants, and oyfters, no others belonging tothis clafs occurred to my notice. Nor does the Euxine pro-duce any curious ßell-ßß). Oyfter-beds appear to exift alongthe whole rocky coaft; but thofe near Kaffa afford a fmallfpecies, with thin fliells of various colours. At the fame place,the common mufcle, or Mydia, is plentiful, large, and well-flavoured; often containing, as already has been obferved,numerous fmall pearls. Thefe, with the oyfters, or Oßridia^and the common Petalides, are a favourite food of the Greeksduring their fafts, as alfo the large fnails, frequent in the vine-yards; befide which, nine or ten other forts of fmall land-fnails are very abundant in the mountainous part of thepeninfula, efpecially one that breeds in all fallow-lands andwoods, and, towards autumn, attaches itfelf in clufters toflirubs, and the ftalks of plants. I have no where met withany rare fea-mufcles ; only the razor-fifh, or Solen, of theBofphorus, which has fhorter fhells than the common kind,and feems to be of a peculiar fpecies. In fome hard calcareousftones, compofmg the fhore, there is inclofed a particular fmallPholas; and the fhip-worms do confiderable damage to veflelsalong the whole coaft»
