Notice of the Foraminifera. By Mr. Lyell.

a. Rotalina. (d. nat. size.) 



b. Cristellaria. (c. nat. size.) 



The above are figures of the two genera of Foraminifera from 

 the upper beds at Timber Creek, alluded to in the paper. 



I am not aware that any attention has hitherto been paid to the 

 fossil foraminifera of the American cretaceous strata, to which I 

 find no allusion in Dr. Morton's works. They are very abundant 

 in the coralline rock of Timber Creek.' Mr. Forbes has examined 

 some of them for me, and these belong to the genera Cristellaria, 

 Rotalina, and Nodosaria. All these genera occur in the chalk of 

 Europe. One of my American species of fossil Cristellaria is 

 specifically identified by Mr. Forbes with C. rotulata of D'Or- 

 bigny > which occurs in England, France, and Germany, ranging 

 from the upper greensand to the white chalk. It is another in- 

 stance of species found most abundantly in Europe, recurring in 

 the American chalk. There are two other species of the same 

 genus at Timber Creek, one of them very large. There are two 

 species of Nodosaria. The Rotalina, which is very abundant, is 

 closely allied to a species of our chalk.
