About twenty-five years ago Prof. B. F. Miiclge eollected a 
nuni])er of marine fossils from sandstone of the Mentor beds 
(then referred to the Dakota) twelve miles southwest of Sa- 
lina. Of the sixteen moUuscan forms reported as thus col- 
lected by him, fourteen were described by Meek in the Fourth 
Annual Report and in volume IX of the Final Report of the 
Hayden U. S. Geological Survey of the Territories, all of these 
being illustrated in the latter volume ; and two were described 
and figured by White in volume IX of the Proceedings of the 
U. S. National Museum and in the Twelfth Annual Report of 
the Hayden Survey. 
The forms described from this terrane by these authors 
as follows :

Meek are young examples; but the Mentor shales yield large
