XVII. Foraminifera Jrom the Chalk of the Ujiper Missouri^ 

 North America. (Monatsber. 1842, p. 187 ; Abliandl. 1841, 

 pp. 365, 398, 429, 433 [1843].) 



In the ' American Journal of Science and Arts,' vol. xli., 

 October 1841, pp. 400-402, the late Prof. J. W. Bailey gave 

 an account of some " American Polythalamia from the Upper 

 Mississippi, and also from the Cretaceous Formation on the 

 Upper Missouri;" and in vol. xlvi. p. 297, &c., the researches 

 of Ehrenberg in these Cretaceous Foraminifera of America are 

 treated of in connexion with a resume of the results of his ex- 

 amination of large quantities of both North- and South-Ame- 

 rican Microzoic deposits, recent and fossil*. At page 307 a 

 woodcut outline of Textilaria missouriensis ^ Ehr., is inserted 

 in a footnote. In the Am. Journ. Sc. vol. xlviii. (1845), p. 341, 

 Prof. Bailey gives a list of the American rocks in which 

 Foraminifera had been found, and from which specimen s had 

 been sent to Dr. Ehrenberg.

 vulgaris, two chambers of N. glabra, D'Orb. Fig. 3, Nod. 

 acus, is the early portion of an extremely attenuate and scarcely 

 segmented variety of N. ovicula. A similar specimen has been 

 figured by Prof. Bailey from the deep soundings off New Jersey 

 and Delaware (' Smithsonian Contrib.' 1861, fig. 8). Fig. 4, «,
