 be this species, and which he has notwithstanding described 

 with thirty-five ribs.

 The length is generally about two inches and three quarters, the 

 breadth two inches, and the height one inch and three quar- 

 ters, but specimens have been found six inches long, with 

 the other dimensions in proportion ; each valve has from 

 thirty-four to forty longitudinal ribs, of which about twelve 

 at the posterior end are imbricated, and somewhat tubercu- 

 lated, and the others crenulated by strong transverse elevated 

 striae, particularly on their sides, and towards the anterior 

 end ; the colour is whitish, irregularly spotted or stained with 

 yellowish brown, orange, or pale purple. It appears pro- 

 bable, from his description, that Chemnitz's figure 191, 

 which Mr. Wood has quoted for C. tuberculatum, may be a 

 variety of this species. 



maculatum. 24. Shell somewhat heart-shaped, 

 ventricose, with longitudinal angular ribs 

 striated transversely on the posterior side.
