The next paper read was from W. J. Broderip, Esq., in which tlie 

 author resumes his descriptions of Mr. Cuming's shells. 



Helix (Carocolla) Virgo. Car. testa subcomplanato-globosa ,

The entirely white variety of this delicate shell (which has the ap- 

 pearance of being framed of the purest wax overlaid with a glassy 

 transparent enamel) is rather smaller than var. a. The animal in 

 both varieties is of a light bluish green, so that when it is with- 

 drawn into tiie transparent shell it produces a strong resemblance 

 to Carocolla Regince ; and indeed, when Mr. Cuming first saw them, 

 he for a moment thought that he had found large specimens of that 

 lovely shell ; but when the animal was taken out, the delusion va- 

 nished. 



Helix (Carocolla) dealbata. Car. testa sordide alba, sub/fa- 

 vescente, subdiaphand, subglobosd, Uneis incrementi obliquis creber-

The dim and sordid white of this species is enriched when the 

 greyish white animal is withdrawn into the shell.

Tlie colour of the animal is dark greyish white.

The animal of this elegantly worked Carocolla is yellowish, some- 

 what like the ground-colour of the shell, which is exquisitely scul- 

 ptured after the manner of engine-turned trinkets. Above, the ele- 

 vated concentric lines are sharp, and the shell on that side has some- 

 what the appearance of a flattened Scalaria : beneath, the elevated
