NOTICE OF NEW CRETACEOUS FOSSILS FROM THE LOWER GREEN 

 MARLS OF NEW JERSEY. i 



BY R. P. WHITFIELD, AMERICAN MUSEUM OF NATURAL 

 HISTORY', NEW YORK CITY'. . 



Mr. Pilsbry recently sent me a few New Jersey fossils for identi- 

 fication ; among them were the following new species which he wished 

 me to describe for the Nautilus. 

 Volutoderma Woolmani n. sp. 



Shell, as shown by the internal cast, somewhat more than an 

 inch in length, and having a diameter of the body volution of seven- 

 sixteenth of an inch in the cast, being more slender than any species 

 yet described. Volutions largest just below the suture and attenuate 

 below, forming a moderately long beak ; marked in the upper part 

 by eight comparatively strong vertical plications, which are obsolete 

 below. Columella marked by three very distinct folds or ridges, the 

 lowest of which is the strongest. These are well marked on the 

 inside of the upper volutions. 



This species like most of those from the New Jersey Green Marls 

 is known only from an internal cast. It retains only two volutions 

 and is imperfect at the base of the beak. It is very distinct, how- 

 1 Illustrations of the following species will be given next month.
