Shell subulate, turrited, smooth, of a dirty brown ; 

 whorls somewhat rounded, entire, the penultimate and ante- 

 penultimate with about four series of small tubercles, the 

 remaining superior whorls with two series of longitudinal 

 folds, their extremities separated by a narrow smooth 

 interval. Aperture oblong, effuse. Columella naked, 

 short, and truncate. No canal. Japan : Dr. E. Siebold. 



70. T. GLAUCA. (pi. xhv. f. 85.) Hindsy 1. c. p. 155. 



Testa turrito-subulata, acuminata, glaucescente ; anfrac- 

 tibus rotundatis, eleganter cancellatis, prope suturam cingulo 

 albido tuberculato ; anfractu ultimo elongato, pallide fasciato ; 

 apertura ovali ; columella contorta. 



Probably only the young of T. radula, nothwithstanding 

 the rather diiferent character of the cancellation, and its 

 glaucous appearance. Native country unknown. 



71. T. BiciNCTA. (pi. xliv. f. 72.) Hinds, 1. c. p. 150. 



Testa subulata, laevigata, nitida ; anfractibus rotundatis, 

 linea impressa divisis, longitrosum phcatis, superne area 

 coarctata, transversim biseriatim super plicas minute tuber- 

 culatis ; plicis tenuibus, acutis, interstitiis laevigatis ; anfractu 

 ultimo concolore. 



Remarkably and very distinctly characterized by the two 

 rows of small tubercles which encircle the whorls beneath the 

 girdling. The shell is otherwise of an uniform white glassy 

 colour, which might be attributable to its condition. Our 

 skilful artist seems to have seen an additional series of tuber- 

 cles ; but except on the last whorl where there are three, I 

 cannot discover more than two. The specimen is unique in the 

 collection of Mr. Cuming. Native country unknown. 



72. T. TUBERCULOSA, (ph xliii. f. 48.) Hinds, 1. c. p. 154. 



Testa turrito-subulata, acuminata, polita, olivacea ; anfrac- 

 tibus planulatis, laevigatis, politis, superne cingulo tuber- 

 culato, area inferiore triseriatim tuberculato ; seriebus duabus 

 superioribus frequenter subevanidis ; antractu ultimo sub- 

 quadrato, unicolore, multiseriatim tuberculato ; columella 

 contorta. 



Shell subulate, acuminate, turrited, polished, pale olive ; 

 whorls flat, shining, above with a nodulous girdle, beneath 

 with about three series of small regularly disposed tubercles, 

 those in the middle being less distinct; last whorl rather 

 square, not banded. Aperture oblong. Columella naked, 

 twisted.
