The above table sbows that the upper limestones at Phillips- 

 burgh must lie on the same geological horizon, very nearly, as 

 that of limestone No. 2 of Point Levi. I am strongly under the 

 impression that eight or ten of the other Phillipsburgh species 

 occur at Point Levi, but it is difficult to identify species of Plevr 

 rotomaria and Orthoceras without good specimens. 



In the palaeontology of New York, Prof Hall notices 13 spe- 

 cies as occurring in the Calciferous sandrock of that State. Of 

 these, three are fucoids and one (^Orthoceras laqueatum) has no 

 locality, Turho ohscura and Pleurotomaria iurgida appear to 

 be one. With the above deductions there are only eight lloUusca, 

 and of these the following occur at Phillipsburgh, 3Iaclurea 

 matutina, Ophileta sordlda, 0. levata, 0. a^mplanata, and pro- 

 bably Holopea dilucula. There are several specimens of Ortho- 

 ceras^ with the septa closely arranged as in 0. primigenium. 

 These species are stated to occur in the higher part of the rock, 

 in the State of New York, and therefore it seems probable that 

 No. 2 at Phillipsburgh represents the upper part of the Calcifer- 

 ous sandrock as developed in the Mohawk valley.
