FLORA OF THE SHASTA FORMATION. 221 



fossils contained in collection No. 5 indicate that the formation containing them is 

 not older than the Aquia Creek stage of the Lower Potomac. They may be as young 

 as the Atane strata. 



All the other collections were sent to Professor Fontaine much earlier 

 and his determinations are embodied in the descriptions of the species 

 given below. 



The accompanying sketch map (PL LXIV) of the general region in 

 California where collections of Shasta plants were made will assist the 

 reader in locating the beds geographically in that State. For those in 

 Oregon, see PL V. 



NOTES ON SOME FOSSIL PLANTS FROM THE SHASTA GROUP OF CALIFORNIA 



AND OREGON. 



By William M. Fontaine. 



The object of this paper is chiefly to give the result of the examination 

 of three parcels of fossil plants collected from the Shasta group of California 

 and Oregon. 



One of the parcels contains fossils collected by Messrs. Diller, Stanton, 

 and Storrs, in 1893 and 1894, from the following localities in California. 

 The numbering is my own, and is intended simply to make reference easy. 



Locality No. 1." — One and one-half miles northeast of Horsetown, Shasta 

 County, Cal. Typical Horsetown beds. Collected by T. W. Stanton, 1893. 



Locality No. 2. — Nofth Fork of Cottonwood Creek, below the mouth of Eagle 

 Creek, Shasta County, Cal. Horsetown beds. Collected by T. W. Stanton, 189.3. 



Locality No. 3. — Eagle Creek, near Ono, Shasta County, Cal. Lower part of 

 Horsetown beds. Collected by T. W. Stanton, 1893. 



Locality No. 4- — Bjrron Gulch, near Ono, Shasta County, Cal. Horsetown beds, 

 slightly higher than No. 5. Collected by T. W. Stanton, 1893. 



Locality No. 5. — Byron Gulch, near Ono, Shasta County, Cal. The lowest 

 fossiliferous horizon of the section. Base of the Horsetown beds. Collected by 

 T. W. Stanton, 1893. 



Locality No. 6. — Aldersons Gulch, 2 miles south of Ono, Shasta Countj^, Cal. 

 Lower part of Horsetown beds. Collected by T. W. Stanton, 1893. 



Locality No. 7. — Cold Fork of Cottonwood Creek, Tehama County, Cal. LTpper 

 KnoxvUle (Aucella) beds. Collected by T. W. Stanton, 1893. 



Locality No. 8. — Elder Creek, 2i miles below Lowry, Tehama Countj'', Cal. 

 Base of the Chico group. Collected by T. W. Stanton, 1893. 



Locality No. 9. — Elder Creek section, 3j miles above Lowry, Tehama County, 

 Cal. Knoxville beds. Collected by Stanton and Storrs, 1893.
