The ornament of the whorls of this well-known species is very 

 variable, though the contour is fairly constant ; the spiral threads 

 are sometimes very close and regularly spaced, more often at 

 irregular intervals, and occasionally far apart in bands of two and 

 three ; the prominent angle at the shoulder may be faintly, 

 distantly tuberculose, or the tubercles may attain to a great size. 

 The extent of the callosity covering the inner margin of the 

 aperture is also variable, but it is always thickest posteriorly, 

 where it spreads over part of the penultimate whorl, and anteriorly 

 on the front half of the columella. 



Dimensio7is. — Length 88 mm.; breadth 49 mm.; length of 

 aperture 42 mm. 



Form, and Loc. — Pliocene : Wanganui, Kew Zealand.
