distant period to characterize them. I have not yet seen Cristellaria 

 rotitla, said by Lyell to occur at Timber Creek, although I have examined 

 several hundred specimens. 



Dentalina, d'Orb. 



D. pulchra. PI. Ixix, figs. 40, 41. Elongated, very slightly arcuate ; 

 cells large, more convex towards the large extremity ; diameters of cells 

 equal ; surface marked by about ten heavy, longitudinal ribs ; sutures ob- 

 literated ; opening small, tubulate and inclined in the direction of the 

 curve.

The Foraminifera of the Cretaceous Greensands from New Jersey. 



From the materials furnished me for examination, I have to thank Dr. 

 Homes, Director of the Imperial Cabinet of Mineralogy at Vienna, Dr. 

 Krantz of Bonn, and especially Prof. .Ferd. Romer of Breslau. The 

 specimens from the first two contained but few foraminifera ; those from 

 Prof. Riimer were quite rich in the same. Unfortunately, however, 

 they were for the most part not well preserved and the more fragile forms 

 were present only in fragments. 



The following is a list of the species found. They all belong to the 

 polymerous Foraminifera, and the few species which appear to me to be 

 new, I have described and figured. 



I. RHABDOIDEA, Schltz. 



a) NODOSARIDEA (m.) 



a) Nodosaria, d'Orb. 



1. N. polygona,^s's,. Zeitschr. d. deutsch. geolog. Gesellsch., 1855, 

 265, pi. vii. figs. 7, 8. Fragments, rare. They are very often found 

 however, in the upper Cretaceous of Mecklenburg. 



2. N. sp. with globular chambers, separated by deep sutures, which 

 are covered with numerous fine longitudinal ridges. The first chamber is 

 equal in size to the following one, and ends in a very short, central spine. 

 I saw only a fragment in which the last chamber was wanting. 



-b) Dentalina, 4'Orb. 



1. D. gracilis, d'Orb. Mem. de la soc. geol. de France, iv. i, 14, pi. 

 i. fig. 5. Very rare elsewhere in the upper chalk formations down to the 

 " Planer." Very widely distributed. 



2. D. colligata, N. sp. PI. vii. fig. 4. Approaching many species of 

 Marginulina. Little bent, obtuse below, with six to seven chambers,
