Fig. 20. 



Turbo marmoratus found in the 

 North Sea passes under a variety of 

 names as Marbled Turbo, Green Snail, 

 Spotted Snail, Banded Snail, Pearl 

 Snail, etc., etc. Coming from the 

 water the animal is furnished with a 

 large operculum and the shell covered 

 with a thick coat of vermetus and 

 lime remains of insects. In fact 

 some we received from the North 

 Pacific (Japan) were so covered with 

 lime material no shell was recogniz- 

 able except at the mouth. 



But it is in the cleaned state the 

 public know this species best. Well 

 cleaned and it shows a beautiful shade 

 of green. By cutting through the 

 green we come to a beautiful pearl, 

 and we have the "Banded Snail" and 

 "Spotted Snail" and removing all the 

 green we have the "Pearl Snail" 

 one of the handsomest pearl shells 

 possible to secure. Where it picked 

 up the name "Snail" we never deter- 

 mined, as it very wrongly confuses it 

 with the Helix.
