Shell ovate-elongate ; spire elevated, fostigiate, apex acuminate : whorls 

 seven, flattened on the sides, po.steriorly rather roundly angulate and gradate- 

 subcanaliculate ; body-whurl a little exceeding half the total length of the

 Length, 64 mm., originally about 06 nnii. ; width. 33 mm., original width 

 about 85 mm.; length of body-whorl to suture, 34 mm.; length of spire, 

 from suture of body-whorl, when entire, about 32 nnii.
