BEE hPL RANS MITTAL, 
New York, October 1, 1888. 
Sir: I herewith transmit to you descriptions and illustrations of the 
Gasteropoda and Cephalopoda of the Greensand Marls and accompanying 
beds of New Jersey, which will form a second part of the report on the 
fossil remains of the State. 
In presenting this second report, I wish again to express my thanks 
for the aid which you have so often given me in the selection and exami- 
nation of material from the many collections under your charge; and also 
to express through you my thanks for the kindness and courtesy with 
which my many demands have been met by the officers of the Academy 
of Natural Sciences of Philadelphia, Pennsylvania, and especially to thank 
their curator, Prof. Angelo Heilprin, who has kindly selected and sent me 
many specimens from the collection under his charge. I have also been 
greatly favored. by the use of specimens from the cabinet at the School 
of Mines of Columbia College in New York, through the kind offices 
of Dr. J. S. Newberry and Dr. N. L. Britton. I have also been allowed 
to use and figure very many specimens from the collection at the Ameri- 
can Museum of Natural History, New York City, for which I must express 
my thanks to the trustees of that institution. There are also several private 
collections to which I am indebted, through yourself, for the use of valu- 
able material and for which I here wish to express my thanks. 
Yours, very truly, 
R. P. Waitrievp. 
Prof. Grorce H. Cook, 
State Geologist of New Jersey.
