"Ail uf the above species are living today in freshwater to somewhat saline lakes, ( )iic 

 species, Anomoeoneis polygraiitma, is living at present in the (ireat Salt i-ake in Utah and in 

 the Gulf of Mexico. Its connnon occurrence in the Indian material suggests that the water 

 was at least somewhat saline, and this is further indicated by the fact that half of the 

 species live in both fresh and brackish water environments. 



Stephanocfisctis astraca iiiiiiiihila, Eunotia suecica, Stauroneis niontaiM, Navicula rein- 

 hardtii, and Pinnnlaria niicrostauron are now living in cool water lakes and suggest that the 

 Indian material was deposited from a cool water lake. These species all occur rarely, how- 

 ever, so thcv ofifer no verv conclusive evidence."
