 Ampullaria recently collected by himself and Dr. T. H. Mont- 

 gomery, Jr., in a creek flowing from the Everglades near Miami, 

 Dade County, in southeastern Florida, specimens of the shell being 

 exhibited. 



The species, which he proposed to name Ampullaria miamlensli, 

 is similar to A. depressa Say, of the St. John's river, in size and 

 general contour, but adult shells are remarkably solid and strong, 

 with the peristome heavily thickened, the callus beiug especially 

 strong at the base of the columella. The color is very dark, with 

 obscure spiral bauds, usually more or less lost in the general 

 duskiness in adult individuals.
