Peek ORS TRANS MITT AL: 
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. mr of the Paleontology of New Jersey. 
In presenting this volume of the report I wish to express my thanks 
to you for the manner in which you have furthered my efforts to obtain 
material for the volume, and also to Dr. N. L. Britton for his kind offices 
in 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. Wurtriecp, 
Geologist. 
Prof. Grorce H. Cook, 
State Geologist of New Jersey.
