RANELLA.— Plate I. 



lower part, striae and ridges slightly undulated, 

 very finely granulated ; white, stained with reddish 

 brown, varices snowy-white ; aperture oblong-oval, 

 canaliculated at both ends, interior faintly tinged 

 with purple ; lip toothed and grooved.

Murex rana, Linnaeus ; Martini, Conch., vol. iv. 

 pi. 133. f. 1270-7). 



Hab. Ceylon. 



How comes it to pass that this common and peculiarly 



characteristic species has escaped the notice of so many j 



good discriminating conchologists who have written i 



the genus ? 



Species 3. (Mus. Cuming.) 



Ranella gigantea. Ran. testd fusiformi-turritd, ven- 

 tricosd, spird valde acuminatd, varicibus rotundatis, 

 oblique separatis ; anfractibus transversim subobso- 

 lete costatis et elevato-striatis, coslis nodosis, striis 

 leviter undulatis ; albidd, fitsccscente timid; colu- 

 mella subrugosd, canali longiusculo, /iris regularibus 

 angustis dorsim ecrlato ; aperturd ovatd, labro den- 

 tate, dentibus binis. 



The gigantic Ranella. Shell fusiformly turreted, 

 ventricose, spire very much acuminated, varices 

 rounded, obliquely separated ; whorls transversely 

 rather obsoletely ribbed and elevately striated, ribs 

 noduled, striae slightly waved; whitish, stained with 

 light brown ; columella a little wrinkled, canal 

 rather long, carved at the back with narrow, regular 

 ridges ; aperture ovate, lip toothed, teeth ranged in 

 pairs.

 Apollo gyrina, De Montford. 



Hab. Mediterranean. 



There is so much confusion among the synonymes 

 which Linnaeus has quoted at different times for the il- 

 lustration of his Murex reticularis, that I have not ven- 

 tured to refer to it. It is cited by some authors for 

 this species, some for the Triton cancellous, others for 

 the Triton olearium, than which there are scarcely three 

 shells belonging to this immediate group of more oppo- 

 site character. 



Species 4. (Mus. Cuming.) 

 Ranella leucostoma. Ran. testd subfusiformi-turritd, 



spird acuminatd, varicibus oblique separatis; an- 

 fractibus transversim tenuissimi striatis, subangulatis, 

 ad unguium nodoso-tuberculatis ; rufo-castaned , api- 

 cem versus interdum albidd, varicibus albimaculatis ; 

 columella, lavi, supern'e callositate armatd ; canali 

 brevwsculo ; aperturd ovatd, fauce alba ; labro intus 

 fortiter dentato. 



The white-mouth Ranella. Shell somewhat fusi- 

 formly turreted, spire acuminated, varices obliquely 

 separated; whorls transversely very finely striated, 

 slightly angulated, nodosely tubercled at the an- 

 gle ; reddish chestnut-brown, sometimes whitish 

 towards the apex, varices spotted with white; co- 

 lumella smooth, armed at the upper part with a 

 callosity ; canal rather short ; aperture ovate, inte- 

 rior white ; lip strongly toothed within.

 p. 542. 

 Triton leucostoma, Quoy and Gaimard. 



Hab. New Holland. 



This is one of those species of Ranella that partake so 

 intimately of the characters of Triton. 



Species 5. (Mus. Stainforth.) 

 Ranella candisata. Ran. testd elongato-turritd; vari- 

 cibus obliquis, paiilu/um separatis ; anfractibus cre- 

 berrime granoso-striatis, granorum striis nonnullis 

 prominulis; anfractibus infra suturam verrucoso-mar- 

 ginatis; lutescente-albd, castaneo-fusco sparsim punc- 

 tata et maculata ; columelld multirugosd ; aperturd 

 ovatd, f auce peculiariter crebrisulcatd ; labro denticu- 

 luto, dentibus binis. 

 The shining-white Ranella. Shell elongately tur- 

 reted ; varices oblique, a little separated ; whorls 

 very closely granulously striated, some of the striae 

 of granules prominent ; whorls verrucosely margi- 

 nated beneath the suture ; yellowish white, spa- 

 ringly dotted and spotted with chestnut-brown ; 

 columella many- wrinkled ; aperture ovate, interior 

 peculiarly closely grooved ; lip denticulated, teeth 

 ranged in pairs.

Murex candisatus, Chemnitz. 

 Murex cunditus, Gmelin. 

 Colubraria granulata, Schumacher. 

 Hab. Island of Annaa, Pacific Ocean, and island of Lu- 

 zon, Philippines ; Cuming. 

 A species of great rarity and beauty, the entire sur- 

 face of which is very closely and curiously granulated.
