I am not aware that the raised longitudinal striae with which this 

 shell is so delicately sculptured are to be found in any other species 

 of the genus. 



Conus ambiguus. Con. testd turbinatd, locvi, basim versus liratd, 

 lineis subtilissimis, undatis, longitudinalibus, subobsolefe incisis ;

 liculatd, maculis arcuatis fuscescentibus ornatd, apice mucronato, 

 elato.

There is always a doubtful character about shells exhibiting faint 

 indications of colour ; I have not, however, succeeded in referring 

 this to any species hitherto described, 



Conus lentiginosus. Con. testd fusiformi-turbinatd, tenuiculd, 

 Itevi, basim versus sulcatd, sulcis latiusculis, profundis ; albidd, 

 fuscescente lentiginosd et punctatd ; spird elatd, anfractibus acut-

 labro subexpanso, juxta spiram emarginato. 

 Conch. Icon., Conus, pi. 44. f. 245.

This is an interesting and important species, of which there is a 

 fainter specimen, of more elongated growth, in the collection of 

 Mr. Adamson of Newcastle. 



Conus trochulus. Con. testd abbreviato-turbinatd, obesd, solidd, 

 lavigatd, basim versus sulcatd; albd, apertures fauce rubido-vio- 

 laceo tinctd ; spird obtuso-convexd, lavigatd. 

 Conch. Icon., Conus, pi. 45. f. 246.

This species, of which there are several examples in the British 

 Museum, all with the violet-tinged aperture, exhibits the same con- 

 trast of colour as a very peculiar white variety of the Conus nivosus. 



Conus sugillatus. Con. testd turbinatd, solidiusculd, lavigatd, 

 basim versus subobsolete noduloso -liratd ; albidd, fasciis duabus 

 latissimis livido-olivaceis, lineisque exilibus fuscescente-punctatis, 

 cinctd ; spird plano-convexd, canaliculatd, apice mucronato, elato, 

 anfractuum marginibus subtilissime oblique nodulosis ; basi et 

 apertures fauce violaceo tinctd. 

 Conch. Icon., Conus, pi. 45. f. 247.

This shell may probably have been confounded with the Conus 

 lividus ; it is, however, quite distinct from that species both in the 

 detail of the painting and in the structure of the spire. The spire 

 is canaliculated, and very peculiarly beaded with fine oblique nodules,
