which ascends the spire above the sutures. Having a band of 

 hydrophanous cuticle below the peripheral girdle, usually almost 

 entirely lost. 







Spire conoid, apex very obtuse. Whorls 5-J, the first nearly 

 planate, the last slightly deflexed in front. Aperture large, blue- 

 white within ; lip narrowly expanded, purplish-pink ; columella of 

 the same color, subvertical, nearly straight, faintly obliquely trun- 

 cated below. Alt. 72, diam. 64 mill.

The typical C. sarcinosa is a large, green shell, with a brown 

 peripheral band. It is so intimately connected with the following 

 that I am unable to say whether some of the specimens before me 

 should be considered turgens or sarcinosa, and am therefore com- 

 pelled to unite the species, as Pfeiffer at one time did.

Typically smaller than sarcinosa, the prevailing color brown 

 instead of green. The hydrophanous cuticle is disposed in numer- 

 ous revolving bands, interrupted irregularly by oblique brown 

 streaks. Peripheral brown band either present or wanting.
