Abstract. The author says that " many other details might be men- 

 tioned, iiW pointing to the one conclusion that, in i)assing over geo- 

 graphical areas of sedimentary deposits of even a few hundred miles 

 in extent, especially when the direction is vertical to the probable coast 

 line of the ])eriod, the effects of those changed conditions recorded in 

 the difterent nature and structure of the deposits, and of other con- 

 ditions only recorded in the fossils themselves, which were probably 

 ditierences of temj)erature and ocean currents, must be borne in mind 

 in classifying the deposits."

The specimen was found in the bluish sandstone (which in places is a 

 line pebbly conglomerate) at Le Boeuf, called the " third oil sand,*' by Mr. 

 1. i). White in the Beport Q of the /Second Oeol. Survey of Fennsijlva- 

 nia (j). 239), and regarded by him as the equivalent of the third oil sand 

 of the Venango oil district of that State. In the same stratum an<l 

 above it are typical Chemung fossils. The author describes it under 

 the name of FresHvichia I'Jriensis, and gives three figures ol" it on page 

 48.
