BRACHIOPODA OF THE MIOCENE MARLS OF NEW JERSEY. 
A single species only of this group of shells has been obtained or 
noticed from these formations within the limits of the State. The form, a 
Discina, appears to be quite abundant in the marls at several of the locali- 
ties, but so far none but upper valves have been obtained, not the least 
part of a lower valve being found so far as could be detected. The 
absence of this class of animal life in these Miocene deposits is not so 
remarkable when one takes into consideration the fact that there is almost 
as complete an absence of them in all the American Atlantic Tertiary 
deposits, and but very few even in the older Cretaceous deposits over the 
same areas. 'T'o be sure, in the Cretaceous there is, through a portion of 
New Jersey, a superabundance of individuals of two of the species— Tere- 
bratula Harlani and Terebratella plicata—but in species even these deposits 
are remarkably deficient, only six species probably being known in the 
Cretaceous within the State, one of which, 7. Atlantica, is quite doubtfully 
of Cretaceous age.
