RANELL A. 



Species 6. (Mus. Cuming.) 

 Ranella ventricosa. Ran. testd acuminato-ovatd, tenui, 

 ventricosissimd, varicibus subindistinctis ; anfractibus 

 angulatis, ad angulum fortiter tuberculatis, transver- 

 sim striatis, subgranosis ; albidd, luteo-castaneo va- 

 riegatd, cingulis castanets angustis subdistantibus or- 

 natd ; columell6 Itevi ; canali brevissimo, latiusculo ; 

 aperturd ampld, faun' alba ; laliro crenato, super/A' 

 profundi sinuato. 

 The ventricose Ranella. Shell acuminately ovate, 

 thin, very ventricose, varices rather indistinct ; 

 whorls angulated, strongly tubercled on the angle, 

 transversely striated, slightly granulated ; whitish, 

 variegated with yellowish chestnut, ornamented 

 with rather distant narrow chestnut hands; colu- 

 mella smooth ; canal very short, rather broad ; in- 

 terior of the aperture white ; lip crenated, deeply 

 sinuated at the upper part.

 Douai, p. 426. pi. 34. f. 1 and 2. 

 Hub. Bay of Callao, Peru ; Cuming. Chili ; Potiez and 

 Michaud. 

 The varices of this shell are very indistinctly deve- 

 loped, and do not follow immediately one under the 

 other. The lip is deeply sinuated at its junction with 

 the body whorl after the manner of a Pleurotoma, and 

 the tubercles of the last whorl exhibit a somewhat un- 

 usual arrangement in being lower on one half of the 

 back of the whorl than on the other. 



Species 7. (Mus. Stainforth.) 

 Ranella spinosa. Ran. testa elongato-ovatd, depressd, 

 varicibus spinis duabus longiusculis fortibus armatis ; 

 anfractibus superneleviter angulatis, exiliter noduloso- 

 liratis, /iris tuberculis brevibus acutis sparsim muri- 

 catis ; fu/vo-fusirseeute, cingu/is castaneis angustis 

 subindistincte ornatd; columella depressd; canali 

 subextenso ; laliro intus crenato. 

 The spined Ranella. Shell elongately ovate, de- 

 pressed, varices each armed with two strong, rather 

 long spines ; whorls slightly angulated at the upper 

 part, faintly nodulously ridged, ridges muricated 

 here and there with short sharp tubercles ; tawny 



brown, ornamented with rather indistinct narrow 

 chestnut bands ; columella depressed ; canal some- 

 what extended ; lip crenated within.

Murex rami, var. B. Linnaeus. 

 Rufonaria spinosa, Schumacher. 

 Hah. Mauritius, Ceylon (found on coral reefs) ; Hennah. 

 This was the only spined example of the genus until 

 the recent discovery of a beautiful smaller species, 

 Ranella peeti/iata (vide PL VII.), collected by Mr. Hinds 

 during the late expedition of H.M.S. Sulphur, and de- 

 scribed in the ' Zoology' of that voyage. 



Species 8. (Mus. Cuming.) 



Ranella foliata. Ran. testd ovato-conicd, ventricosa, 

 liris elevatis, numerosis, eonfertis, granulatis, undi- 

 que ci/ictii, interstitiis striis longitudinalibus subtilis- 

 sime cancellatis ; anfractibus medio angulatis, tuber- 

 culorum acutiusculorum serie unicd ad angulum ar- 

 matis ; lamina columellari sii/ili/issimr rugosd, vividi 

 rubro-aitruntiu, expansd, superne in sinu altofoliato, 

 varicem pratereunte, desinente ; labri exterioris mar- 

 gine expanso, rugoso-denticulato, vivide rubro-au- 

 rantio. 



The foliated Ranella. Shell ovately conical, ventri- 

 cose, everywhere encircled with numerous close- 

 set granulated raised ridges, the interstices between 

 which are very finely cancellated with longitudinal 

 stria? ; whorls angulated in the middle, armed upon 

 the angle with a single row of rather sharp tubercles ; 

 columellar lamina very finely wrinkled, bright red- 

 dish orange, expanded, extending at the upper part 

 into a lofty foliated sinus, deposited by the side of 

 the varix ; margin of the outer lip expanded, ru- 

 gosely denticulated, bright reddish orange.

 Ranella crumena, Kiener (not Lamarck). 



Hub. Mauritius ? 



It is really a most unpardonable error for M. Kiener 

 to have confounded this beautiful and very characteristic 

 species with the Ranella crumena (vide PI. IV.), after the 



July 1844.
