T. subulata, cylindrica; anfractibus plano-convexis, longitudi- 

 naliter valde plicato-costatis, costis angulatis, arcuatis, intersti- 

 tiis transversim sulcatis ; superne sulco cingulatis ; apertura elon-

ITab. Insl. Hawaii. 



Shell subulate, cylindrical ; whorls flatly convex, longitudi-

 red stains in the interstices of its ribs.
