et fai observe des differences specifiques constantes. Cette soi-disant 

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

 ment dit, et cest sans doute ce qui explique pourquoi un certain nomhre 

 de conchyliologues veulent que le Scrobiculator soit une Ranelle. Pour 

 nous, qui en avons vu I'animal, cest un Triton." Note in new edition 

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



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

 fractihus superne depressis, ad suturam granulatis, infra Icevibus, 

 transversim noduloso-liratis, in medio tuber culorum seriebus duabus 

 compressis armatis ; lividd, fuscescente varid ; columelld subtiliter 

 rugosd; aperturd ovatd, utrinque sinuatd; labro denticulate. 

 Conch. Icon., Ranella, pi. 6. f. 28. 

 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, zond albidd in medio cinctd; columelld Imvi, 

 canali longiusculo. 

 Conch. Icon., Ranella, pi. 7. f. 33. 



Hab, ? 



The plicated growth of this shell is developed with the neatest 

 regularity from the apex to the margin. 



Ranella venustula. Ran. testd ovatd, crassiusculd, varicibus 

 valde obliquis ; anfractibus trajisversim costatis, granulatis et 

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

 lum fortiter tuberculatis ; columelld excavatd, nigricante-purpured , 

 albigranulosd ; aperturd rotunda, utrinque canaliculatd, fauce 

 roseo-purpured ; labro incrassato, nigro-purpureo. 

 Conch. Icon., Ranella, pi. 7. f. 37. 



Hab. ? 



This species is remarkably characterized by its rich dark purple 

 columella granulated with white. 



Ranella siphonata. Ran. testd ovatd, crassiusculd, varicibus 

 perspicue canaliculatis ; anfractibus transversim rude costatis et 

 tuberculatis, undique granulatis et punctatis, prope suturam cor- 

 rugatis ; luteold ; columelld via: rugosd, roseo-purpurascente ; aper- 

 turd rotundd, fauce roseo-purpurascente, utrinque canaliculatd, 

 canali super o valde elato-siphonato.

tatd; columelld albd, apertures fauce albd. 

 Conch. Icon., Ranella, pi. 7. f. 38. 

 Hab. Philippine Islands ; Cuming. 



I take this shell to be quite distinct from the dark variety of the 

 Ranella bufonia to which it is allied. 



Ranella tuberosissima. Ran. testd ovatd, varicibus perspicue
