Species 10. (Mus. Cuming.) 



Ranella c^elata. Ran. testa pyramidali-ovatd, de- 

 pressd, subponderosd, castaneo-fuscescente, striis cos- 

 tisque granoso-moniliformibus, nigricante-fuscescen- 

 tibus, cingulatd, anfractHs ultimi cost is inferioribus 

 confertioribus ; columella granuloso-rugosd, rugis ni- 

 tidis ; lahro planissime fimbriate, supern'c si/mato, 

 fusco, radiatim albisulcato. 



The carved Ranella. Shell pyramidally ovate, de- 

 pressed, rather ponderous, chestnut-brown, encir- 

 cled with blackish brown, granuled, necklace-like 

 ribs and stria 3 , lower ribs of the last whorl closer ; 

 columella granulously wrinkled, wrinkles white ; 

 lip very flatly fimbriated, sinuatedat the upper part, 

 brown, radiated with whitish grooves.

" This handsome species," says Mr. Broderip, " re- 

 minds the observer of some of the antique carved orna- 

 ments in oak and chestnut. The apex of the spire is 

 generally eroded." 



M. Kiener has erroneously abandoned the Ranella 

 aetata as being the Ranella semigranosa of Lamarck, 

 leading M. Pfciffer, in his notice of the genus Tritonium, 

 into the same speculative error. Mr. Broderip's account 

 of the sculpture of the species in question does not very 

 well accord with the anfractus ultimi dorso nudo of 

 Lamarck's Ranella semigranosa. 



Species 11. (Mus. Cuming.) 

 Ranella pustulosa. Ran. testdovatd,subdepressd,pon- 

 derosd, castaned : anfractibus pustulorum grandium 

 seriebus duabus tribtisve livido-castaneis cingulatis ; 

 varicibus grauu/oso-liratis ; columelld granuloso-ru- 

 gosd, rugis albidis ; labro planissiine fimbriate, su- 

 jierur sinuato, fusco, radiatim albisulcato. 

 The pustulous Ranella. Shell ovate, somewhat de- 

 pressed, ponderous, chestnut-coloured ; whorls en- 

 circled with two or three rows of large livid chest- 

 nut-coloured pimples ; varices granulously ridged ; 

 columella granulously wrinkled, wrinkles white ; 

 lip very flatly fimbriated, sinuated at the upper 

 part, brown, radiated with whitish grooves.

This shell approximates so closely to the Ranella cw- 

 lata in the style and character of its sculpture, that a 

 specimen or two of different ages seem all that is neces- 

 sary to exhibit a complete specific connection between 

 them ; it has however been demonstrated by the re- 

 searches of two gentlemen of perhaps the greatest prac- 

 tical experience, Mr. Cuming and Mr. Hinds, that no 

 species of shell common to the western coast of South 

 America has ever been discovered on the coast of Africa. 



Species 12. (Mus. Cuming.) 



Ranella Argus. Ran. testa ocatd, crassiusculd, subde- 

 pressd, varicibus planulatis .■ trauscersim striata, lon- 

 gitudinaliter plicato-nodosd ; pallide lutescente-spa- 

 diced, castaneo fasciatd, faseiis regularibus, nume- 

 rosis, confertis ; columella Itevi, canali brevissimo ; 

 aperturd amphi, fav.ee alba ; labro intus crenato,prope 

 canalem acute dentato. 



The Argus Ranella. Shell ovate, rather thick, a little 

 depressed, with the varices flat ; transversely striated, 

 longitudinally plicately noduled ; pale yellowish 

 bay, banded with chestnut-brown, bands regular, 

 numerous, close-set ; columella smooth, canal very 

 short ; aperture large, interior white ; lip crenated 

 within, sharply toothed near the canal.

 nah. 



Lamarck describes the Ranella Argus as being ocel- 

 lated ; I have not however made mention of the appear- 

 ance which suggested the name of the hundred-eyed 

 monster for this shell, because it is accidental. The 

 transverse chestnut-brown bands pass with regularity 

 directly over the nodules, and they merely become white 

 or ocellated by the colouring matter being occasionally 

 worn off. 



Species 13. (Mus. Cuming.) 

 Ranella vexillum. Ran. testd fusiformi-ovatd, vari- 

 cibus planulatis, liris depressis transversim calatd. 



July 1844.
