From Macdonald county the shells are 10 mm. diam- 

 eter; from Dade county only 9 mm. The body whorl is 

 so constricted behind the peristome that the greatest di- 

 ameter is not from a point on the lip, but on the whorl 

 back of it.

Pilsbry says this has not been found south of Sedalia, 

 Missouri, where I reported it some years ago. Jackson, 

 and other places from which it is now reported are south 

 of Sedalia, and the specimens are of this species; they 

 certainly are neither blandiana nor uncifera. The shell 

 from Jackson is more globose, of something more than 

 five whorls, and the body whorl much more ventricose 

 than in typical specimens. The stria? of increase are 

 scarcely visible on the body whorl, but on the others show 

 some bands of light color. The Allanville shells are 

 larger than the Jackson.
