a wide subsutural and a wide peripheral zone (one or two narrow

bands. 



Spire low, inconspicuous; whorls 41, little convex, the last but 



little descending in front. Aperture large, banded inside, perislome 

 white, broadly reflexed ; columella oblique, wide, nearly straight.

Allied to C. zonifera, but differs markedly in the arrangement of

I m perforate, solid, large, globose-depressed-conoid: Surface finely 

 and obscurely spirally lirulate, the last whorl quite obviously sculpt- 

 ured with obliquely forward-descending malleations forming narrow 

 ridges, becoming concentric beneath. Ground-color clear greenish- 

 yellow, having a dark zone below and another above the periphery. 

 Hydrophanous white cuticle forming numerous narrow encircling 

 bands, mostly worn off in front of the aperture. 



Spire rather conoidal ; whorls 5, but slightly convex, the suture 

 superficial; last whorl slightly descending in front. Aperture large, 

 white and faintly showing the bands inside ; peristome broadly re- 

 flexed, recurved, white ; columella oblique, nearly straight.
