the margin whitish. Peristome simple; nearly semicircular, margin 

 somewhat obtuse, chestnut, slightly thickened toward the columella.

Under a considerable magnification are seen stride of growth and 

 transverse stride, but very indistinct. (Hid.} 



C. LIGNICOLOR Mollendorff. Unfigured. 



Imperforate, subdepressed-globose or globose, subtly striated, 

 chestnut-brown, covered with a streaked and lineated wood-colored 

 hydrophauous cuticle, a rather wide tawny-whitish band at the 

 periphery, and sometimes another around the columella ; spire glo- 

 bose-conoid, apex flat. Whorls 5, convex, the last tumid, above the 

 aperture denuded and shining. Aperture lunate-rotund ; peristome 

 straight, acute, subthickened, brown ; columella wide, rose- white, 

 rather straightened, sloping. (Moll.}

In color and markings it approaches C. depressa Semp. and me- 

 lanochila Val. while it is more globular than the last, and in contour 

 resembles most C. sphcerion Sow. The non-expanded, weakly 

 thickened peristome distinguishes it from all the foregoing, being 

 found only in C. suprabadia Semp. The white peripheral band is 

 lacking on none of the ten examples before me, whilst the circum- 

 umbilical is present upon four only. The height of the spire varies, 

 as the above dimensions show, not inconsiderably, but the higher 

 forms seem to predominate. (Moll.)

Imperforate, conoid-semiglobose, thick, striate, tawny, covered 

 with a thin brown lusterless cuticle; spire convex, obtuse, the apex 

 reddish ; whorls 5, slightly convex, the last more convex, obsoletely 

 angulated in middle, slightly descending in front. Columella
