The correlation of the Oakville beds with that portion of the well re¬ 
ferred by Harris, from its marine molluscan fauna to the Upper Miocene, 
is offered because of my knowledge of the fossil contents of the Oakville 
beds at other localities, and the belief that it represents approximately 
the period of time embraced by the deep well beds, but with different 
conditions of deposition. No exposures have yet been found on the 
Coastal Slope which afford a fauna in anywise comparable with this por¬ 
tion of the deep well, but the Oakville beds appear to be stratigraphically 
their equivalent.
