 purpurea cincta ; spira turrita, acuta, rjradata, sutura incon- 

 spicua ; anfractus 8, ubiqice spiraliter striati, supra medium 

 angulati, infra an[/ulum convexi, longitudinaliter costati {costis 

 in anfr. idt. circ. 12), spiraliter lirati {liris in anfr. pentdt. 4) ; 

 anfractus idtimus spiram suhceqiuvns, infra angulum leviter 

 convexus, basin versus sidycontr actus, vix rostratus ; apertura 

 latiuscula, fauce 2^ur2nireo-grisea ; canali brevissimo, leviter 

 recw'vo ; columella rectiuscula ; labrum acutum, crenulatum, 

 s^iperne sinu profxmdo latiiiscido emarginatum.

 albida ductus, infra medium contractus, breviter rostratus ;
