to the truncation ; thin ; grayish white, becoming slightly purplish 

 brown on the last whorl. Surface lusterless, sculptured with narrow 

 olilique riblets separated by much wider spaces ; whorls 8-9, some- 

 what convex, the last rounded below with an obsolete cord around 

 the base, very shortly free in front. Aperture large, subcircular or 

 somewhat transversely oblong, a trifle brownish within, the peristome 

 shining white, broadly expanded and reflexed ; columella with a dis- 

 tinct fold. Axis encircled by two principal compressed lamellae, the 

 lower one largest, denticulate above the middle and extending to the 

 last whorl, the upper disappearing to the penultimate whorl ; in the 

 median whorls a cord is sometimes interposed, particularly in the 

 ante-penultimate whorl.

The complete shell contains 16-18 whorls with a total length of 

 24—28 mm. The rejected portion is rib-striate with smooth and 

 somewhat bulbous lip. Differs from TJ. fallax by its color, more en- 

 larged aperture and by the columellar axis.

NOTES. 



New Color Varieties of Helix (Dentellaria) badia 



Fer There is in my collection a series of Helix badia Fer., 



habitat unknown, which exhibit considerable variation from the type 

 in their coloring. To call attention to their character I may be 

 justified in giving names to these extreme forms. 



As Dr. Pilsbry points out in the Manual (Vol. V, p. 86) the type 

 of 6a(^/a is " uniform dark chestnut colored." Between the typical 

 form and the variety I first describe is a transition stage which is 

 represented by an example before me. 



Var. roseolabrum, n. var. Differs from the type in being much 

 lighter in color and having a rose-colored peristome. Type in my 

 own collection. 



Var. unicolor, n. var. Distinguished by the light-colored shell 

 and pure white peristome and teeth. In the example before me the 

 umbilicus is not completely covered. Type in my own collection. 

 This form should not be confused with Piisbry's var. guadeloupensis. 

 The latter is chestnut-colored and carinated at the periphery.
