 tant nodes on the upper part of the body volution; spire subtri- 

 angular, having curved longitudinal ribs visible beneath the

Melania sylvserupis, n. sp. PI. 9, fig. 10. 



Specific chaj^acterisation. — Size and form as indicated by the 

 figure; spiral whorls but slightly inflated above, but becoming 

 more Garinated below; body whorl very angular or carinate with 

 nine short oblique costae, marked below by a few rather faint re- 

 volving lines. The only specimen known is somewhat incom- 

 plete, but it shows very distincftly a new form of a brackish or 

 fresh water type in this generally marine fauna. 



Locality. — Ala.: Woods bluff. 



Type. — Lea Memorial collecftion, Paleont. Mus., Cornell Univ. 



It is quite probable that land shells also may be found at Woods
