“T. globulosa, testula microscopica superficie levi, in adulta longiore quam lata, 
articulis globosis.” Enrenspere. (1838, Abhand. Akad. Berlin, p. 135.) 
T. globulosa, microcsopic test with a smooth surface, adult forms longer than 
wide, with spherical or globular chambers. 
Locality. Meeker county, Little Fork river, Minn. Saline county, Neb. South Chicago, Ills. 
Textularia globulosa is very abundant in the Minnesota clay and chalky lime- 
stone, and common in Nebraska, the specimens from that material being very fine. 
In the south Chicago material they are quite common and well preserved. 
Dr. G. M. Dawson, in his paper on the Foraminifera of the Cretaceous rocks of 
Manitoba, gives the following description of 7. globulosa: “A stout form with glo- 
bose chambers rapidly increasing in size at each addition, and sometimes even as 
broad as long. The primordial chamber, and those next to it, are often bent away 
several degrees from the axis of symmetry of the larger part of the shell. The sur- 
faces of the chambers are marked with extremely minute diagonal interrupted 
ridges or wrinkles.”} This description is far superior to that of Ehrenberg. The 
species has also been found in Dakota, and in the “Eolian sand” from the Smoky 
Hill river, near Lindsborg, Kansas. 
Textularia americana Ehrenberg. ‘This species forms a very large part of the 
mass of the chalk rocks of the upper Missouri and Niobrara rivers. It is found ina 
light cream colored Cretaceous marl on the upper Mississippi, called there “ prairie 
chalk”; has been examined by Prof. Bailey, and figured, but not described, in the 
Amer. Journ. Sci., xli. p. 401, 1841.*
