 cotypes, coll. L. E. Daniels, La Porte, Indiana; Phil. Acad. Sci., Penn. 



TYPE LOCALITY: Turkey Lake, Kosciusko County, Indiana. 



ANIMAL, JAW, RADULA and GENITALIA: Not examined. 



RANGE : Indiana. A race of the Upper Mississippian region. 



RECORDS. 



INDIANA: Turkey Lake, Kosciusko Co. (Daniels). 



GEOLOGICAL DISTRIBUTION : Unknown. 



ECOLOGY: Not recorded. 



REMARKS : Blatchleyi may be known by its long spire, regularly 

 increasing whorls and rounded body whorl. It is smaller than typical 

 palustris and differs markedly in its spire and aperture, palustris having 

 a large, corpulent shell with large aperture. The present race differs 

 from Galba elodes and Galba elodes jolietensis in its more rounded 

 and more regularly increasing whorls. Alpenensis has a broader shell 

 with a differently shaped inner lip and spire. 



Efforts to include this form with the described varieties of palustris 

 have proven futile. It lives in Turkey Lake in large numbers, is very 

 uniform in shape and size and is certainly entitled to a name. I take 

 great pleasure in dedicating this interesting race to Mr. Blatchley, State 

 Geologist of Indiana. The shells were discovered and collected by 

 Mr. L. E. Daniels, and were previously reported as Lymnaa palustris 

 michiganensis, which small specimens somewhat resemble.

J In the synonymy only the references to Say's original elodes (besides 

 one or two others) are included, as most authors have used the name to cover 

 the majority of the palustris-like forms of America. Under palustris all of the 

 remaining- references to elodes are given.
