Family CORNACE^. 



CORNUS FEKOX? Ullgei'. 

 CoRNus FEROX Unger. Lesquereux, Proc. U. 8. Nat. Miis., Vol. XI, p. 21, 1888. 



A single much-broken example is all that was t'ound. Its identifi- 

 cation is extremel}' d()ul)tful, and is permitted to stand simply for the 

 purpose of calling attention to the fact that there is present in these 

 beds a large leaf that, while resembling Cornus ferox^ is of practically 

 unknown affinity. For purposes of correlation it is obviously of no 

 value. 



Locality. — Cherry Creek, Crook County, Oregon. Collected by 

 Maj. Charles E. Bendire (U. S. Nat. Mus., No. 2452).
