38 THE NAUTILUS. 



ever from any species previously noticed, being much smaller and 

 of more slender habit. The external markings are unknown. The 

 specimen is from the Lower Green Marls at Lenola Station on the 

 Long Branch Division, Pennsylvania Railroad in Burlington Co., 

 New Jersey. The type is in the collection of the Academy of 

 Natural Sciences of Philadelphia. Collected by Mr. Lewis Woolman 

 of Philadelphia for whom it is named. 

 Cerithium Pilsbryi n. sp. 



Shell elongated and slender; volutions numerous, number not 

 determined, very gradually expanding with additional growth ; 

 apex and aperture unknown. Volutions slightly convex between 

 sutures, and ornamented by a band of small oblique nodes immedi- 

 ately below the suture ; also by a series of larger vertical folds which 

 extend across the exposed part of the volution, below the upper band 

 of nodes, and numbering something more than one half as many to 

 the volution as the nodes above. There are also very fine spiral 

 striae almost too fine be seen without magnifying. The lines of 

 growth are fine but distinct, and take a broad sweeping backward 

 curve between sutures. Apical angle fifteen to eighteen degrees. 



This species is a new type for the New Jersey cretaceous, and I 

 know of none of the same type in the rocks of this age in North 

 America ; while in the Cretaceous of Palestine there are several 

 species already described. The one most nearly like this being that 

 described in the Bulletin Am. Mus. Nat. Hist, for December, 1891, 

 figured on PL IX of Vol. Ill, figs. 11 and 12, under the name 

 Cerithiam Conradi ; the point of diflerence between them being the 

 exact reversal of the lines of nodes, the upper one here being small 

 while on that one it is the largest. These specimens consist of concre- 

 tionary matrices, in what appear to have been Coprolitic bodies, in 

 one of which there are fragments of several species of molluscs repre- 

 sented. They are also from the Lower Green Marls at Lenola, N. J. 

 Collected by Mr. Lewis Woolman, and are deposited in the collec- 

 tion of the Academy of Natural Sciences, Philadelphia. 



Another Cerithium-like shell occurs with the above, but is too 

 imperfect for specific description. It presents characters which 

 would most likely ally it to Cerithiopsis. There are imprints of por- 

 tions of six volutions remaining in the matrix showing three lines of 

 nodes on each volution, increasing in size from above downward. 

 This also is an undescribed species. There is also an internal cast 

 of a species of Anchura or liostellaria, which diflfers from any
