 Inhabits the coasts of America. Spengier. Carolina. Petiver. 

 Shell about two inches long, and one inch broad ; one half of 

 each valve is striated longitudinally, and the other half in a 

 contrary direction ; the outside is dark brown, more or less 

 variegated with olive, and the inside is light bluish green; 

 the margin is beautifully shagreened with light green and 

 dark olive scales. Schroeter has erroneously cited the 

 figures both of Born and Chemnitz, which represent two 

 different species, and Gmelin has not corrected this, or 

 hardly any other error which occurs in the Einleitung. Pe- 

 tiver, 1. 1. f. 4. is cited in the 12th edition of the Systema 

 Naturae for C. tuberculatus, and by most other authors for
