Report of the State Geologist. 345 



list shall be completed in all classes of fossils embraced in the 

 Palaeontology of New York. The preparation of such a list of 

 each class of fossils ( to be illustrated ) has been a long time con- 

 templated by the writer and it is very gratifying to be able to 

 present at this time the first installment of the work. 



The requirement to present the Annual Report in October has 

 necessarily left unfinished several communications which would 

 have been completed during the coming months, had the pre- 

 esntation of the report been delayed till the end of the year, 

 which has been the custom until the present occasion. 



Yery respectfully, 



Your obedient servant. 



JAMES HALL, 



State Geologist. >
