On the age of the Tejon rock^of California and the occurrence 

 of Ammonitic remains in Tertiary deposits; by A. Heil- 

 prin. Proc. Phila. Acad. Nat. Sci., Vol. 34, 1882, pp. 

 196-214. 



The author remarks (p. 213) that the rocks of the Tejon group 

 (Cretaceous, Div. B, of the California Survey), despite their com- 

 prising, in their contained faunas, a limited number of forms from 

 the subjacent (Cretaceous) deposits, and a few undoubted representa- 

 tives of the Ammonitidx, are of Tertiary (Eocene) age. 



The Eocene age of the Tejon rocks is also maintained by Prof. 

 Jules Marcou, who made a personal examination of the region.
