SECTION No. 18.— EAST SIDE OF RIVER, NORTH OF THE DAVIS FARM (495 to 530) 



This is the most northerly Outcrop at which the grey rocks of the marine Richmond can 

 be seen with the exception of a small outcrop of the Columnaria reef 200 yards farther to the east 

 on the same side of the river. The contact with the Queenston red shales is not exposed, and it is 

 probable, also, that the uppermost part of the grey beds is covered by drift. In weathered lime- 

 stone beds in the upper two feet of this section, Hebertella occidentalis is very abundant, and the 

 following fossils are also found: Homotrypella hospitalis, Byssonychia sp., Modiolopsis sp., and 

 casts of ramose bryozoans.
