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

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



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



nitidd, subdiaphand, lineis incrementi obliquis creberrime striata, 



suturis et anfractds basalis angulo subelevatis subcrenatis, vix 



umbilicatd ; aperturd auriculato-angulatd ; labii limbo subreflexo. 



Var. a. Alba, labii limbo purpureo-brunneo. Long. ^; lat. l|r poll. 



Var. b. Tota alba, 



Hab. ad insulam Zebu, foliis arborum hoerens. 

 Legit H. Cuming. 



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 the 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, subfla- 

 vescente, subdiaphand, subglobosd, lineis incrementi obliquis creber- 

 rime substriatd, vix subumbilicatd ; aperturd auriculatd, magnd ; 

 labii limbo vix substriato. Long. -}-§ ; lat. If poll. 

 Hab. in insula Siquijor, foliis arbusculorum hserens. 

 Legit H. Cuming. 



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

 greyish white animal is withdrawn into the shell. 



Helix (Carocolla) Puella. Car, testa globosd, diaphand, lineis 

 incrementi obliquis creberrime substriatd ; aperturd auriculato-ro- 

 tundatd ; labii limbo subreflexo. 

 Hab. in insula Camiguing, foliis arbusculorum adherens. 

 Var. a. Alba, anfractu basali lined brunned subcentrali cincta. 

 Var. b. Tota alba. 

 Legit H. Cuming. 



The colour of the animal is dark greyish white. 

 Helix (Carocolla) Rota. Car. testa complanatd, rotundatd, 

 subdiaphand, umbilicatd, superne lineis elevatis, acutis, infra lineis 

 elevatis haud acutis, concentricis, regularibus corrugatd, flave- 

 scente ; anfractibus superne medio bilineatis, anfractds basalis infra 

 unilineati angulo acuto, dentato, unilineato ; lineis castaneis ; aper- 

 turd auriculatd ; peritrematis unidentati limbo subexpanso albo.

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
