«A shell, which seems to be quite common from Georgia 

 to Texas, and which Dr. Binney regarded as Ihe southern form 

 of //. thyroidus, though some of his specimens are labelled 

 claiisa? They have the glol)ular form of H. clausa, somelimes 

 even approaching to H. elevata in height; the aperture is large 

 and rounded, the umbihcus generally quite closed, and the 

 columella sometimes possesses and as often is destitute of a 

 tooth like H. thyroidus. I think further observation will 

 establish its claim as a distinct species, and in such case I 

 would propose for it the name of H. bucculenta. » ( Gould in 

 Proc. Bost. Soc. 1848. p. 39.)
