No. 3.— This fine, well-marked specimen from the City 

 Quarry, belongs to the Genera Callyptgraptus of Dr. 

 Spencer, F.G.S. The name was suggested by the over- 

 lying branches of the GraptoUtes. It differs from all I 

 have seen in the Chert beds, and 1 believe it will prove 

 to be a new species.
