HELIX. 



to be reduced to elongated points, widely separated from one another. 

 A variety usually smaller, more depressed, and consequently with 

 wider aperture, and having a faint brown spot at the insertion of 

 the columella, has been described by Dr. Westerlund under the 

 name of H. recondita. I have had the types of the species from 

 Mr. Westerlund; they are identical with mine. It seems to me im- 

 possible to separate H. recondita specifically." 



; A second variety, more like the type in general form, and ap- 

 proaching H. recondita in the columellar spot, has been named by 



me var. CONTAMINATA this variety frequently has 



the umbilicus partly open ; the coloration is like that of the type, 

 but with the maculations or points more intense. It has below a 

 more or less interrupted chestnut band." 



' The third variety, which I have called UZIELLIANA (pi. 60, figs 

 76-80) is relatively very depressed, the columellar margin dark, the 

 umbilicus decidedly open. It is the form which authors have look- 

 ed upon as the type of the species, and called H. carseolana."

Var. UNIARMATA Paulucci. PI. 65, figs. 35, 36. 



Differs from the typical carsoliana of Ferussac by the somewhat 

 larger shell, somewhat compressed below, the umbilicus nearly clos- 

 ed ; aperture widened, the margins subparallel, the lower strongly 

 callous or dentate, with a brown spot at its insertion.

Var. MILKTTIAXA Paulucci. PL 65, figs. 37, :>,s. 



Differs from the type in the much larger conic shell, the last whorl 

 wider, much inflated ; columella callous, widely brown-maculate ; 

 peristorne brown. Diam. 22, alt. 15 mill.

Covered perforate or umbilicate, depressed-globose solid, opaque, 

 shining, white, encircled by two to four, usually three deep chestnut 

 bands, the lower two subcontinuous, sometimes unicolored white, very 

 lightly irregularly obliquely striate and with numerous microscopic- 

 spiral impressed lines, especially obvious near the aperture, spire low 

 depressed conic, apex corneous, blunt, the first whorl convex, the 

 following lightly convex, but with a flattened appearance; whorls
