Pleurotoma pica. Pleur. testd crassd, obtuso-pyramidali, albd, t 

 maculis fuscis, paucis, grandibus, subquadratis, irregulariter va- 

 riegatd ; anfractibus eleganter semicostatis, costis angustis, nume-

Pleurotoma alabaster. Pleur. testd turritd, intus extusque ni- 

 ved, roseo interdum leviter tinctd, transversim subtilissime sulcatd 

 et striatd; anfractibus longitudinaliter costatis, superne subde- 

 pressis ; sinu lato. 

 Conch. Icon., Pleurotoma, pi. 8. f. 65. 



Hab. Island of Siquijor, Philippines (found in loose coral sand on 

 the reefs at low water) ; Cuming. 



The sculpture of this shell is exceedingly delicate, the cross grooves 

 looking as if they had been graved with an etching-point. 



Pleurotoma venusta. Pleur. testd obeso-fusiformi, flavicante, 

 fusco-maculatd ; anfractibus rotundatis, transversim multicostatis, 

 oblique maculatis, superne depressis, maculis majoribus vivide pic- 

 tis ; canali elongate. 

 Conch. Icon., Pleurotoma, pi. 9. f. 79. 



Hab. Island of Siquijor, Philippines (found in coral sand on the 

 reefs at low water) ; Cuming. 



This highly interesting shell, which is at present unique in Mr. 

 Cuming's collection, differs materially, both in form and in the colour 

 and character of the marking, from any of its congeners. 



Pleurotoma eximia. Pleur. testd gracilefusiformi, albd, anfrac- 

 tibus convexis, costis angustis longitudinalibus, striisque transversis 

 elevatis, eximie cancellatd ; sinu subindistincto ; canali mediocri, 

 leviter tortuoso. 

 Conch. Icon., Pleurotoma, pi. 10. f. 82. 



Hab. Island of Masbate, Philippines (found under stones at low 

 water) ; Cuming. 



The canal of this Muriciform species, though somewhat indistinct, 

 fully entitles it to a place amongst the Pleurotomce. 



Pleurotoma albibalteata. Pleur. testd ovato-oblongd, luted, 

 albibalteatd, anfractibus convexis, transverse lineatis, longitudi- 

 naliter noduloso-costatis ; labro incrassato, sinuparvo; canali brevi,
