of these identical species, and it is quite likely that some of the 

 species credited to South Amboy, on the authority of Prof. New- 

 ben*y, may really have come from within the Magothy forma- 

 tion, since the Morgan locality, which is of Magothy age, would 

 not have been kept distinct from South Amboy as a place name 

 in Prof Newberry's day. The following table of distribution 

 gives in detail the geological and geographical distribution of 

 all the species known to occur in the Raritan formation at the 

 present time. The species found recorded from "near Keyport," 

 in Prof. Newberry's report, are all excluded, as this outcrop is 

 now known to be of Mag^othy age, while the TiliaephyUiun re- 

 corded from Fish House is now known to be Pleistocene. As 

 previously mentioned, no account is taken of the determinations 

 of Lescjuereux, published in the Clay Report of 1878, since the 

 material was so unreliable and embraced a number of forms 

 which would be most unlikely to occur in these beds.
