I have been unable to consult the original description of this 

 species, published in 1876, and hence have depended upon the 

 other authorities cited above, the description being taken from 

 de Folin's account in Le Naturaliste. The figures are from 

 Kobelt. 



Var. hyalina Folin. Similar to monodonta, but the shell is 

 without the warm coloration; instead of being a fine tawny 

 color it is crystalline; the outer margin is also less dark and 

 only roseate. 



Var. wbcylindrica Folin. Shell narrower, more lengthened, 

 subcylindric, whorls often 7, nearly flat; usually subhyaline or 

 hyaline. Length 4.3, diam. 1.3 mm., whereas the typical form 

 of monodonta measures 3.6 x 1.5 mm.
