Var. angidata. Testa anfr. superne oblique angulatis, lineis obliquis 

 rufescentibus ornatis. Coll. Sylvanus Hanley.

 anfr. ult. lineis duabus rufis cincta, altera supra, altera peripheriam 

 infra ; spira elongato-coniea ; anfr. 8 ?, laeves, politi, apice ? (defi- 

 ciente) basique anguste sulcati, suturam infra zona pellucida cincti ; 

 apertura parva, spira longe brevior ; columella arcuata, brunneo 

 tincta, cum labro callo tenui juncta ; labrum crassiusculum, intus 

 denticulatum.

 paululum suturam supra, et in anfr. ult. lineis tribus pallido-rufis 

 cincta ; spira convexo-conica, sutura distincta ; anfr. 8-9 convexi- 

 usculi, spiraliter levissime sidcati, apicem basimque versus vali- 

 diores, suturam infra zona sordido-vitrea cincti; anfr. ult. an-

Resembling a variety of P. virgatus in colour j but it is 

 thin, semipellucid, with the spire less conical and more con- 

 vex, the body-whorl narrow and rounded at the periphery, 

 and the outer lip thin and not denticulate ; and the infra- 

 sutural vitreous band at once separates it.
