MIOCENE MOLLUSC A AND CRUSTACEA. 15 



And in the marls from Jericho, N. J., the following were obtained: 



Clavulina communis D'Orb. 



Truncatulina lobatula Walker and Jacobs sp. 



From the very small amount of the marls examined this would indi- 

 cate a somewhat prolific field for the investigation of these minute 

 bodies, and I have deferred for the present the illustration of these species 

 and the Bryozoans and a single coral of the Miocene deposits, hoping 

 to be able to insert them at an early day in. a volume embracing the Corals, 

 Echinoderms, and other invertebrate remains of the Cretaceous and Eocene 

 marls of the State. 



The geological horizon of the Miocene marls of New Jersey would 

 hardly be considered as differing from those of the more southern States — 

 Maryland, Virginia, and the Carolinas— whatever the geological age of 

 those deposits may be, Miocene proper, or Mio-Pliocene, as some are dis- 

 posed to call it. No living forms have been found in the New Jersey 

 deposits that are* not also known to occur in some of the more southern 

 localities, and no very close representatives of living species are seen 

 among those which so far are found in New Jersey only. Of this latter 

 group there are thirty-six species, as given in the following list. (Triforis 

 terebrata may be identical with T. moniliferuni H. P. Lea, in which case 

 there would be only thirty-five.)
