TRITON. 



tlie celebrated Tynan purple, whence it was denominated 

 Purpura, The Triton variegatus is much valued by the 

 inhabitants of some of the South Sea Islands. 



Of fossil species there are very few, those with 

 which we are acquainted are only found in the newest or 

 tertiary beds, above the chalk; as in the London clay, and 

 in its contemporaneous formations, in the green sand_, &c. 



We have represented in our plate the following spe- 

 cies, which show the principal variations in general form 

 to which the genus is subject 3 the Tr. Anus being one of 

 the most remarkable.
