This shell, which is of a solid, shining white (like the celebrated 

 marble of Paros), has been evidently confounded with the Conus co- 

 lumba ; it requires however no very great exercise of critical discri- 

 mination to perceive that it differs materially both from that and the 

 preceding species. 



Conus exaratus. Con. testd turbinatd, subangustd, per totam su- 

 perficiem sulcatd, sulcis regularibus, latiusculis, interstitiis subti- 

 lissime striato-cancellatis ; pallide cceruleo- purpurea, maculis fer- 

 ruginosis albinubeculatis, perpaucis, parcis, sparsim ornatd ; spird 

 acuminatd. 

 Conch. Icon., Conus, pi. 44. f. 238. 



Hob. ? 



This is a very distinct species, remarkable for the regularity with 

 which it is grooved. 



Conus ustulatus. Con. testd subelongato-turbinatd, superne tu- 

 midiusculd, margine rotundatd, transversim subtilissime liratd; 

 pallide ustulato-rubidd, baited albidd angustd in medio cinctd; 

 spird convexd, spiraliter striata, maculis perpaucis sparsis pur- 

 pureo-rubris ad marginem superior em ornatd; apice mucronato. 

 Conch. Icon., Conus, pi. 44. f. 239. 

 Hab. New Holland. 



There is no trace of any purple-red spots or other dark character 

 on the body of the shell. 



Conus aculeiformis. Con. testd elongate -turbinatd, subfusiformi, 

 undique sulcatd, sulcis subtilissime striato-cancellatis, nunc an- 

 gustis, liris intermediis planis latiusculis, nunc latioribus, liris 

 intermediis rotundatis angustis ; albidd, fuscescente punctata, ma- 

 culis fuscescentibus biseriatim cinctd ; spird acuminatd, apice elato, 

 acuto. 

 Conch. Icon., Conus, pi. 44. f. 240. 



Hab. Cagayan, island of Mindanao, Philippines (dredged from 

 sandy mud at the depth of from twenty-five to thirty fathoms) ; Cu- 

 ming. 



The specimens collected by Mr. Cuming at the above-mentioned 

 island are mostly smaller than those here figured. 



Conus violaceus. Con. testd elongato-turbinatd, cylindraced, tenui, 

 nitidd ; violaced, transversim obsolete fuscescente punctato-lineatd, 

 fuscescente longitudinaliter strigatd, aut sparsim maculaid ; strigis 

 subdistantibus, lineis brevibus fuscescentibus, exiliter albiarticu- 

 latis, ornatis ; spird rotundato-obtusd, spiraliter striata. 

 Conch. Icon., Conus, pi. 44. f. 241. 



Hab. Matnog, island of Luzon, Philippines (found on the reefs) ; 

 Cuming. 



This is a very interesting species ; the faint dotted lines with which 

 the entire shell is encircled are scarcely visible on the violet ground 

 without the assistance of an ordinary lens, but in passing over the 

 longitudinal streaks of light brown they present a more decided ap- 

 pearance. 



Conus tabidus. Con, testd turbinatd, leviter pyriformi, tenui, un-
