ACADEMY OF NATURAL SCIENCES. 235 



Ammonites in the Auriferous Slates of California. 



BY WILLIAM P. BLAKE. 



Ammonites occur in the gold-bearing slates of Bear Yalley, Mariposa County, 

 in addition to belemnites and other fossils already noted. The specimen I have 

 seen is a cast, somewhat distorted by pressure, but apparently similar to the 

 species from the slates on the American River, which I brought to the notice 

 of the academy last year.
