"The shell is generally much compressed, and nearly equally convex on the two 

 sides ; the peripheral edge is round, and the aperture is placed almost symmetrically 

 in the median line. Some specimens are depressed at both umbilici, others are 

 umbonate at one or both ; sometimes the earlier convolutions are visible to a nearly 

 equal extent on both faces. The coarse perforation of the shell wall is usually more 

 conspicuous on the inferior than on the superior face." BRADY loc. cit. 



Locality. Saline county, Nebraska, and South Chicago, Illinois. 



Anomalina ammonoides is a very common Cretaceous foraminifer in Europe; in America we believe 

 this is the first time it has been noticed.
