RANELL A. 



Species 10. (Mus. Cuming.) 



Ranella nobilis. Ran. testd oblongo-ovatd, depressd, 

 crassiusculd ; spird acuminatd, varicibus angustis, ra- 

 diatim stellatis ; anfractibus graniiloso-liratis. prir- 

 cipue super varices, in medio tuberculatis, anfractu 

 ultimo tuberculorum seriebus duabus artnato ; albidd, 

 fuscescente subtililer maculosd; columella fortiter 

 rugosd ; aperlurd oblongd, utrinque canaliculatd, fauce 

 albd ; labro fortiter rugoso. 



The noble Ranella. Shell oblong-ovate, depressed, 

 rather thick ; spire acuminated, varices narrow, ra- 

 diately starred; whorls gnmulouslyridged, especially 

 over the varices, tuberculated in the middle, last 

 whorl armed with two rows of tubercles ; whitish, 

 finely spotted with light brown ; columella strongly | 

 wrinkled ; aperture oblong, canaliculated at both 

 ends, interior white ; lip strongly wrinkled.

Hab. ? 



The form of this noble species is somewhat interme- 

 diate between that of the Ranella pulchra, or " Finned 

 Frog," and the ordinary type of the genus, the varices 

 exhibiting an indication of that peculiar star-like radia- | 

 tion common to the former, whilst the aperture is of an i 

 oblong canaliculated form, with the wrinkled lip and co- 

 lumella of the latter. The sculpture most resembles 

 that of the Ranella foliata. 



Species 17. (Fig. a and b, Mus. Cuming.) 

 Ranella crumena. Run. testd oval a, ventricosd; spird 

 breviusculd, acuta ; unfraclibiis subtilissim'e grutw- 

 loso-striatis, in. medio acutissime tuberculatis, anfractu 

 ultimo tuber Hilar inn. seriebus tribus i/istanlibus ar- 

 mato; albido-spadiced, fusco jnxta tuberculos macu- 

 latd; columella rugosd, aurantio-rubro tinctd; aper- 

 turd subampld, utrinque canaliculatd ; labro planis- 

 simo-effuso, subindistincte denticulato, aurantio- 

 rubro tincto. 

 The leathern-purse Ranella. Shell ovate, ventri- j 

 cose ; spire rather short, sharp ; whorls very finely , 

 granulously striated, very sharply tubercled in the ■ 

 middle, last whorl armed with three distant rows of 

 tubercles ; light bay-colour, spotted with brown 

 next the tubercles ; columella wrinkled, stained 



with orange-red; aperture rather large, canalicu- 

 lated at both ends ; lip flatly effused, rather indi- 

 stinctly denticulated, stained with orange-red.

Variety /}. Fig. a. 



Testd fuscescente et carulescente varid , maculis fuscis juxta 

 tuberculos saturatioribus, seriebus granularibus alter- 

 natim majoribus. 



Shell variegated with light brown and blue, brown spots 

 next the tubercles of much deeper colour, rows of 

 granules alternately larger. 

 Ranella Cavitensis, Beck. 



Hab. Cavite, Bay of Manila (found in sandy mud at low- 

 water) ; Cuming. 



No one can fail to distinguish this characteristic and 

 well-known species, which has been referred, I think er- 

 roneously, by Lamarck, Anton and others to the Murex 

 rana of Linnaeus, for which see Ranella albivaricosa, Sp. 2. 



M. Kiener (Curator of Lamarck's collection!) has de- 

 scribed and figured an example of the Ranella foliata for 

 the Ranella crumena, and one of the Ranella crumena for 

 the Ranella elegans.
