" There has been much variation in the opin- 

 ions of naturalists respecting the proper place of 

 genus Dentalium. Cuvier, a very celebrated 

 writer, agreed nearly with Lamarck ; but still 

 more recently it has been considered as nearest 

 to a new genus, Fissurella, (Patella.) The 

 fossil-shells are found in London clay in great 

 numbers ; in the marie at Folkstone, &c. 



" Spirorhis. All the species are minute, 

 fixed upon sea-weeds, and other marine sub- 

 stances. The animal which inhabits them is 

 of a deep red colour.
