ASSISE E, le. 



The fossiliferous seams here consist of greenish gray sand, alternating *. 

 with others that are lavender gray. The sand consists largely of grains of 

 pellucid quartz ; there are pale green particles and films which may be 

 glauconite or some magnesian silicate. There are also black grains and 

 a few lumps of calcium phosphate. Some of the fossils are fragmentary.

The above assises belong to the lower division of the Etcheminian, 

 and although the matrix imbedding the fossils is fine it alternates with 

 grit sandstones and quartzite in different parts of the division, so there 

 was considerable diversity of conditions when this division was laid down. 

 In the next division, the rocks are coarser and of a more uniform 

 character. 



ASSISE E. 2 a 



On Dugald brook there are in this assise two species of Lingulella but 

 they are not in such a condition as to be worth study, as the shells have 

 been subjected to much corrosion, 



We have referred here provisionally the fossils of Young point near 

 George river station, as they are in red sandy members of the Etcheminian 

 and some distance above the base of the terrane. The species are :
