76 HELICID^. 



Geographical Distribution. Found in Florida, and 

 more abundantly in Texas, especially in the region of 

 Galveston. 



Remarks. This species is very variable in its pro- 

 portions, but is easily distinguished from our other spe- 

 cies by its small aperture, elongated spire, and its color ; 

 its golden interior in fresh specimens, instead of the 

 usual silvery lustre, being its principal characteristic. 

 Its characters agree pretty well with a Mexican species 

 described by Mr. Say under the name of S. undidata ; 

 and if any of our species were in view in- that descrip- 

 tion, it must have been this one. In fonn it most resem- 

 bles S. avara, but it differs in size and color. The short- 

 est specimens resemble S. campestns, but there is no 

 fold of the columella. — [g.]
