ASSISE E. 3/ 



Gray shale more sandy than the assise below ; some beds havs a purp- 

 lish tint ; the spangles of a silvery mica, are larger than those of E. 3e. 

 Some of the highest beds arc flaggy and more silicious.

Though we have associated this assise with the Upper Etcheminian 

 Fauna, there are some changes in its species from the typical grouping 

 of that fauna. Acrothele avia is replaced by A. proles, to which there is a 

 resembling species in the Paradoxides lamellatus Subzone in New Bruns- 

 wick ; also the large Leptobolus is chiefly a variety of L. collicia. The 

 presence of a Solenopleura might also be thought to indicate connection 

 with a higher fauna, but it has not the short eye-lobes of the species of 

 the Paradoxides Zone, and so may be considered more primitive. We 

 have therefore thought it advisable to follow the lithological indications, 

 and include this assise in the Etcheminian. 



*The species marked with an asterisk were found at Gillis, Indian brook.
