LETTER OF TRANSMITTAL. 



New York, May 28, 1889. 



Dear Sir: I herewith transmit to you the descriptions and illustra- 

 tions of the Mollusca and Crustacea of the Miocene formations of New 

 Jersey, which will form Vol. in of the Paleontology of New Jersey. 



In presenting this volume of the report I wish to express my thanks 



to y r ou for the manner in which you have furthered my efforts to obtain 



material for the volume, and also to Br. N. L. Britton for his kind offices 



m collecting and furnishing specimens and information. To Dr. W. H. 



Dall, of the Smithsonian Institution and National Museum at Washington, 



I am under special obligation, as he not only obtained for me the loan of 



all New Jersey material at the National Museum, but also sent Mr. Frank 



Burns into the field in New Jersey, where he made extensive collections 



and transmitted them to me for use. Had it not been for this generous act 



I should have had but a very meager showing of species for this report. To 



the National Museum I am thus indebted for the loan of material and the 



expenses incurred in collecting. To Prof. Angelo Heilprin and to the 



Academy of Natural Sciences of Philadelphia, from which I had the loan of 



all their collections of New Jersey material through Prof. Heilprin's good 



offices, embracing the types of many of the species previously described, 



I also wish particularly to express my thanks. 



Yours, very truly, 



R. P. Whitfield, 



Geologist. 

 Prof. George H. Cook, 



State Geologist of New Jersey.
