Conch. Icon., Ranella, pi. 6. f. 26. 



Hab. ? 



This interesting species, -vvhich Mr. Cuming possesses in different 

 stages of growth, is the shell figured by Mr. G. B. Sowerby, jun., in 

 the ' Conchological lUustrations ' as a variety of his Ranella scrobi- 

 culator (Triton scrobiculator, Lamarck and others) ; I think, how- 

 ever, •vvith M. Deshayes, that it is " une coquille qui me parait tou- 

 jours diffhente ; j'en ai vu plusieurs exemplaires et plusieurs figures, 

 et j'ai observ^ des differences specifiques constantes. Cette soi-disant 

 variui a plutot les caracteres des Ranelles que le Scrobiculator propre- 

 vient dit, et c'est sans doute ce qui explique pourquoi un certain nomhre 

 de conchyliologues veulent que le Scrobiculator soit une Ranelle. Pour 

 nous, qui en avons vu l'animal, c'est un Triton." Note in new edition 

 of Lamarck's Anim. sans vert., vol. ix. p. 626. 



Ranella livida. Ran. testd ovato-turritd, spird acuminatd ; an- 

 fractibus superne depressis, ad suturam gramilatis, infra lavibus, 

 transversim noduloso-liratis, in medio tuberculorvm seriebus duabus 

 compressis armatis ; lividd, fuscescente varid; columelld subtiliter 

 i'ugosd ; apertvrd ovatd, utrinque sinuatu; labro denticulato.

Ranella granifera, Kiener (not of Lamarck). 



Hab. Island of Annaa, Pacific Ocean (found on the coral reefs) ; 

 Cuming. 



I do not see how M. Kiener can identify this tuberculated shell 

 ■with Lamarck's description of Ranella granifera. 



Ranella plicata. Ran. testd oblongd, sub-Muriciformi ; anfrac- 

 tibus rotundatis, scabris, longitudinaliter plicatis, in medio nodu- 

 losis ; livido-olivaced, zona albidd in medio cinctd ; columelld Icevi, 

 canali longiusculo.

The plicated growth of this shell is developed Avith the neatest 

 regularity from the apex to the margin. 



Ranella venustula. Ran. testd ovatd, crassiusculd, varicibvs 

 valde obliquis ; anfractibus transversim costatis, gramilatis et 

 punctatis, superne angulatis, prope suturam corrugatis, ad angu- 

 lumfortiter tuberculatis ; columelld excavatd, nigricante-purpured, 

 albigranulosd ; aperturd rotundd, utrinque canaliculatd, fauce

 columella granulated vvith ^vhite. 



Ranella siphonata. Ran. testd ovatd, crassiusculd, varicibus
