The followiiiii; is a catalo2:ue of the Clinton fossils obtained 

 at Hamilton and Dundas. This catalogue does not contain all 

 the species that are included with the Niagara group proper, 

 which Col. Grant and myself have found in the so-called Clinton 

 beds, but only the more conspicuous species, or those not found 

 higher up at H;imilton.
