A REVIEW OP THE VOLDTIDAE 



lip thin, simple. 



The group Is viviparous and the 

 soft parts too large to entirely enter the 

 shell.

Shell Irregularly ovate, marbled 

 with white and brownish red, covered with a 

 thin brown epidermis, which Is coated for 

 about one-third of the shell, with the 

 enamel-like glaze, which takes Its commence- 

 ment near the pillar. The spire Is deeply 

 channeled and carlnated, exposing the sub- 

 glandiform apex, and forming with the sub- 

 reflected, sharp upper border of the body 

 whorl, a wide, spiral excavation. The up- 

 per edge of the outer lip recedes from the 

 spire. The pillar, which Is very much 

 curved, has three plaits, and Is bordered 

 on the basal half, with a rich chestnut 

 longitudinal band (Broderlp).

Shell, subcylindrical, clouded with 

 white and reddish. The spire somewhat ex- 

 cavated, and the subglandlform apex con- 



spicuous. The area much less, and the 

 channeling much shallower than in C. cyn- 

 blum{C. clsium clslum); the pillar, which 

 has four plaits, much stralghter, the aper- 

 ture narrower, and the whole shell more 

 slender and symmetrical. The sharp upper 

 border of the lip is very much Inflected 

 towards the spire, and the shell Is covered 

 with a thin, brown epidermis, which is 

 covered with the enamel-like glaze for about 

 one-third of the shell, beginning near the 

 pillar (Broderlp).

Shell ovate, tumid, ventricose, of 

 a browhish-red, covered with a strong brown 

 epidermis, over which an enamel-like glaze 

 is extended from the pillar over about a 

 fourth part of the shell, leaving the epi- 

 dermis of the back uncoated. In full grown 

 specimens, the spire and apex are entirely 

 concealed, and the upper border of the body 

 whorl, which is carlnated and somewhat re- 

 flexed, overhangs both, so as to form an 

 open, somewhat round concavity. The pil- 

 lar is four plaited (Broderlp).
