Semper regards this as probably a variety of C. metaformis. 



< '. FULIGINATA Martens. Unfigured. 



Shell conic-globose, lightly striatulate, smoky-brown, hydroph- 

 unous, having two pale yellow zones, one just above, the other 

 below the suture, the last visible upon the last whorl only, and 

 .-mall, irregular, shining brown-black spots ; spire conical, apex 

 obtuse ; whorls 5, joined by a superficial suture, the last rounded, 

 somewhat descending in front. Aperture oblique, square-rounded, 

 palate cserulescent, parietal wall brown-black ; peristome narrowly 

 reflexed, thickened, bluish-white, outwardly rubescent ; columellar 

 margin rather oblique, nearly straightened, (v. Mart.) 



Alt. 25, greater diam. 26 , lesser 23 mill. ; aperture, oblique alt. 

 18, width including peristome 16 mill.

In -vnrral form it reminds one of C. balteata and orbitula Sowb., 

 Imt tin- columellar margin is more oblique than in the first, and 

 longer than in the latter of these two ; the spire is more pointed 

 abovi- than in either of the species named, so that this snail stands 

 l>"t \vt-n these and Cochlostyla (7) viridix. The coloring, however, 

 i- UK m- that of the group Orthostylus, being similar, for instance, to 

 that of C. rnfnijustra. (Mart.)
