The Upper Cretaceous of the Western Gulf area contains 
littoral sand beds of a magnitude great enough to be considered 
formational units. These are not restricted to a narrow horizon 
and the belief has been frequently expressed and is apparently 
probable that these sand formations are the time equivalents of 
several marine formations that are differentiated elsewhere in this 
area. The Woodbine sand of northeastern Texas is a case in 
point and another example is furnished by the Bingen sand of 
southwestern Arkansas. Both are without marine fossils so far 
as known and both contain fossil plants, those of the Woodbine 
sand having been reviewed by mef in 1912. 
Recently Mr. H. D. Miser, of the United States Geological 
Survey, has sent me several small collections of fossil plants from 
the Bingen sand. These are, so far as I know, the first fossil 
plants collected from the Bingen sand. While the material is 
poor and not greatly.varied, a number of species are determinable 
and these, while not as conclusive as might be wished, nevertheless 
shed considerable light on the correlation of the formation. Mr. — 
Miser is to be congratulated for the care with which he has 
collected from such unpromising material. 
The Bingen sand was named by Hill in 1888t from the town
