 Helix carinata, Min. Conch, t. 10. 



11 AviNG ascertained by more perfect specimens that the 

 Helix carinata, Min. Conch., and Pleurotoma flammi- 

 gera of Phillips are the same species, I have taken the 

 opportunity, while figuring some others of the same genus, 

 to give another representation of that shell : the former 

 figure did not show the zigzag marks of colour which are so 

 remarkably preserved, nor the formof the aperture, which 

 is probably the reason why Prof. Phillips did not think his 

 P.Jlammigera to be the same. The outline at the back 

 shows the size it sometimes attains. 



De Koninck, in his work on the fossils of Belgium, has 

 figured it with its coloured marks, and Goldfuss (tab. 183. 

 f.9.) has given the same shell, but neither of these authors 

 has yet published the name.
