CONUS DOMINGENSIS. 



Testa turbinata, subpyriformis, crassiuscula, Isevis, spira elevata, spiraliter striata, 

 anfractibus primis subcoronatis, marginibus subelevatis, ultimo anfractu postice 

 subventricoso, antice striato, striis granosis, moniliformibus. 



This is a somewhat variable species, particularly in the elevation of 

 the spire. 



CoNUS SOLIDUS. 



Testa turbinata, conica, crassa, Isevis, spira subproducta, Isevi, anfraetuum margi- 

 nibus rotundato-elevatis ; anfractu ultimo striato, striis paucis, subobsoletis, 

 canal! recto. 



This fossil is remarkable for retaining some traces of its living 

 colours, the spire is marked with light rusty-brown dashes, and there 

 are three rows of spots of the same colour on the last volution. 



CoNUS CATENATUS. Pl. IX. fig. 2. 



Testa oblongo-turbinata, spira producta, mucronata, anfractibus canaliculatis, ul- 

 timo anfractu laevi, antice obsolete sulcato, liris nonnullis granosis, sulcis alter- 

 nantibus, granis paucis, parvis, distantibus. 



CoNUS CONSOBRINUS. 



Testa oblongo-turbinata, crassiuscula, granulosa, spira conica, elevata, coronata, 

 spiraliter striata, ultimo anfractu zonis elevatis, angustis plurimis granosis, ca- 

 nali subproducto. 



Also a variable species ; in one specimen the granose zones only 

 ^over half the shell. It bears some resemblance to Conus cedo-nulli. 



Oliva cylindrica. 



Testa subcylindrica, spira brevi, retusa, labii columellaris dentibus validis, obtu- 

 siusculis, calli umbilicali dentibus sex ad septem elongatis, quorum altero brevi. 



Cypr^a Henikeri. Pl. IX. fig. 3. 



Testa obovata, ventricosa, inflata, laevis, dorso postice irregulariter tuberculifero, 

 lateribus, prsecipue sinistro, obsolete granosis ; extremitatibus, postica brevis- 

 sima, antica subproducta, apertura angusta, marginibus dentatis, dentibus pau- 

 cis, magnis, rotundatis, canali brevissimo, reflexo. 



This species bears a general resemblance to Cyprcea Mus and seve- 

 ral others, which occasionally have irregular tubercles on the poste- 

 rior part of the back ; it may however be easily distinguished from 

 all such by the dentition of both edges of the aperture, the teeth in 

 this species, though not numerous, being large and prominent. 



Marginella coniformis. 



Testa oblongo-ovata, antice acuminatior, spira brevissima, submucronata, apertura 

 rectiuscula, angusta, labii externi margine inflexo, lato, crasso, depresso, ad api- 

 cem continue, margine interno crenulato ; labio columellari antice incrassato, 

 supra anfractum ultimum extenso, plicis quatuor, prominulis, distantibus, dua- 

 bus anticis elongatis, obliquis, parallelis, antica latus alterum canalis formante, 

 antepenultima minus parallela, postica transversa. 



This species comes nearest to Marginella Amygdala of Kiener ; it
