Mollusca and Crustacea of the Miocene Formations of New Jersey.

(1894). 
Previous to the publication of this monograph by Professor Whit- 
field, the fossils of the Miocene beds of New Jersey have never been 
systematically studied and recorded. A few of the most prominent 
species have been described here and there by different authors. Mr. 
F. B. Meek mentions only seventeen species from New Jersey in his list 
of Miocene fossils published in “‘Smithsonian Miscellaneous Contribu- 
tions.” In his “‘ Tertiary Geology of the Eastern and Southern United 
States,’ Professor Heilprin enumerates twenty-seven species, seventeen 
of which he gives as peculiar to New Jersey. The same author, in an 
article on ‘‘ The Miocene Mollusca of the State of New Jersey,” enumer- 
ates thirty species, but later adds to this list from collections obtained 
from the marl pits at Shilo, giving fifty species from this one 
locality. The total number of species known up to 1887 was eighty-two. 
-In,the present work one hundred and four species are. recognized, 
thirty-six of them, so far as known, being peculiar to New Jersey. The 
author states, however, that there is no doubt that many more might 
be obtained were the beds more thoroughly examined and more local- 
ities visited. 
A list of fourteen species of foraminifera are recorded, determined 
by Mr. Anthony Woodward of the American Museum of Natural 
History, obtained from a few ounces of marl from the interior of some 
of the shells. 
The geological horizon of these New Jersey beds is considered by 
Professor Whitfield not to differ from that of the beds in Maryland, 
Virginia and the Carolinas, whether they be strictly Miocene or Mio- 
Pliocene as some are disposed to call them. 
The fossils described are illustrated by twenty-four plates and are 
distributed as follows: Lrachiopoda, 1 sp., Lamellibranchiata, 6% sp., 
Gasteropoda, 41 sp., and Crustacea, 1 sp. S. W.
