The Cassis rufa appears to be the species most in 

 request for the manufacture of ordinary cameos, owing to 

 the great thickness of the enamel, which is frequently 

 deposited in a dozen to twenty layers. Large quantities 

 of these shells are imported for the pui'pose, and the 

 species has become a common article of merchandise. 



The Cumis pemmta of Lamarck, for the illustration of 

 wldch the author refers to Martini's Conch. Cab. vol. ii. 

 pi. 36. f. 372-3, is undoubtedly the young of C. nifa.
