 C. NEBULOSUS, Solander. PI. 7, figs. 31-34. 



Spire concavely elevated, tuberculate, closely striate ; nebu-

 parts of the surface ; encircled by close narrow brown lines,

 (figs. 32-34). The latter has usually been considered a distinct 

 species, but its characters of narrower shoulder and spotted 

 lines have no distinctive value.
