Shell oblong, rather thick, smooth, of a pale colour, \^^th pale, 

 fuscous subtriangular spots, sprinkled over with chesnut dots, spire 

 short, subconical, with a papillary apex ; volutions five, of which the 

 two or tlu-ee last are furnished posteriorly \nth small sharp spines; the 

 suture very finely spinulose; the last volution elongated, anteriorly 

 subattenuated ; aperture oblong ; columella with four distinct folds. 



Tliis species does not appear to have been ever noticed either 

 by Lamarck or Swainson, although sufficiently well described and 

 figured by Chemnitz, vol. x. f. 1385, 1386. We still use Chemnitz's 

 name {Voluta Cpnbiola), for Kiener's assertion that Lamarck had 

 already given that name to another species is not true. We have 

 represented two varieties; our f. 75 is in Mr. Cuming's collection 

 and f. 76 in the British Museum, 



3. Voluta Corona (pi. Iv. f. 120, 121.), Chemn. 



Testa obovata, ex cameo albida, punctis rufescentibus omata; 

 longitudinaHter striis exarata, striis in anfractuum suturas exeunti- 

 bus in spinas subtilissimas et acutissimas ; anfractu ultimo postice 

 spinis coronata, spinis antice fornicatis ; columellae phcis quatuor 

 anticis distinctis, posticis nonnullisque minoribus : apice papillari. 



Shell obovate, whitish flesh coloured, ornamented with reddish 

 dots, longitudinally striated, with the stria? at the sutures of the 

 volutions running out into very fine and acute spines ; last volu- 

 tion posteriorly cro^vned with spines, wliich are vaidted anteriorly ; 

 colmnella with four distinct folds anteriorly, and several smaller 

 posteriorly. 



We formerly thought that the shell figured by Chemnitz, vol. x. 

 f. 1387, 1388, was only a young shell of V. Ci/mhiola; however, 

 upon reading over his description in German, we find he mentions 

 a character that does not belong to V. Cymbiola — he there men- 

 tions, besides four principal folds on the columella, several smaller 

 folds above them. We have therefore copied Ms figures and drawn 

 up our description from his, as we have never seen the shell. 



4. Voluta luteostoma (pi. li. f. 59.), Chevin. ; V. c%sos- 

 toma, Swains. 



Testa turbinata, crassa, laevi, albicante, lineis angulato-flexuosis 

 maculisque angularibus continuis fusco-castaneis picta, spira brevi, 

 subconica, apice obtuso, anfractibus primis tribus Isevibus paUes- 

 centibus, cseteris tribus postice subangularibus, spinis bre^^bus 

 acutis fornicatis coronatis; anfractu ultimo maximo; apertura 

 elongata, antice latiori, intus aurea, labio externo rotundato, sub- 

 incrassato, phcis columellse 4, validis.
