LETTER OF TRANSMITTAL. 



New York, March 31, 1884. 



Dear Sir: I herewith transmit to j^ou the following descriptions and 

 illustrations of the Brachiopoda and LamelUhrancMafa of the Green Marls and 

 accompanying Clays of New Jersey, which form a part only of the paleon- 

 tological report on the fossil remains of the State. 



In presenting the report allow me to express my sincere thanks for the 

 many kindnesses which I have received at the hands of yourself and your 

 assistant. Professor Smock, in obtaining material for the work. I am also 

 greatly indebted to the officers of the Academy of Natural Sciences at 

 Philadelphia, Pennsylvania. I have' besen obliged to borrow largely from 

 their collection, as it contains very many of the types of Mr. T. A. Conrad 

 and Mr. W. M. Gabb, as well as of Dr. S. G. Morton, and those of Mr. Isaac 

 Lea's species of Unionidce. I am, however, under special obligation in this 

 respect to Profs. A. Heilprin and H. Carville Lewis. I have also had the loan 

 of specimens from Columbia College, N. Y., through Dr. J. S. Newberry, and 

 from Dr. Lawrence Johnson and Miss F, M. Hitchcock, of New York, to all of 

 whom I wish to express my thanks. I have also availed myself largely of 

 specimens from the cabinet at Rutgers College under your charge, and 

 from the cabinet of the American Museum of Natural History in New York 



City. 



Yours, very truly, 



R. P. WHITFIELD. 



Prof. George H. Cook, 



State Geologist of New Jersey.
