et fai observe des difftrences sp^cifiques constantes. Cette soi-disant 

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

 ment dit, et c'est sans doute ce qui expliqite pourquoi un certain no7nbre 

 de conchyliologues veulent que le Scrobiculator soit une Ranelle. Pour 

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

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



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

 fractibus superne depressis, ad suturam granulatis, infra Icevibus, 

 transversim noduloso-liratis, in medio tuberculorum seriebus duabus 

 compressis armatis ; livida, fuscescente varid ; columelld subtiliter 

 rugosd ; aperturd ovatd, utrinque sinuatd ; labro denticulato. 

 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, zona albidd in medio cinctd ; columelld l(Evi, 

 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 transversim costatis, granulatis et 

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

 lum for titer tuber culatis ; columelld excavatd, nigricante-purpured, 

 albigranulosd ; aperturd rotunda, utrinque canaliculatd, fauce 

 roseo-purpured ; labro incrassato, nigra -pur pur eo. 

 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 vix rugosd, roseo-purpurascente ; aper- 

 turd rotundd, fauce roseo-purpurascente, utrinque canaliculatd, 

 canali supero valde elato-siphonato. 

 Var. /3. Testd albd aut luteold, nigra -ccerulescente fasciatd et punc- 



tatd; columelld albd, aperturce 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 perspicuh 

 canaliculatis ; anfractibus transversim rude costatis, dorsim tube-
