“The test is usually much compressed, and widens rapidly towards the distal 
end; the lateral edges are thin and slightly lobulated, the chambers somewhat 
inflated, and the septal lines correspondingly depressed on the exterior; the walls 
are thin and smooth.” Brapy, loc. cit. 
Locality. Meeker county, Minn.; Saline county, Neb.; South Chicago, Ill. This species does not 
seem to be very widely distributed; only two specimens found, one in Minnesota, and the other in 
Nebraska. The specimens figured by Ehrenberg were from the Cretaceous beds of Missouri and Mis- 
sissippi.* We believe that in the fossil state it has only been found in North America,

“Guadryina pupoides is an easily recognized species. Its dimorphous mode of 
growth is generally very apparent, and its variability is limited to such features as 
the number of segments, the relative length and breadth of the test, and the degree 
of lateral compression. In recent shells the walls are thin and calcareous, smooth 
externally, and almost invariably of a greyish hue; fossil specimens sometimes 
exhibit a slightly rough exterior. In form and position the aperture resembles that 
of the typical Textularie, but it is often surrounded by a raised lip or border.” 
Brapy, loc. cit. 
Locality. Meeker county and Little Fork river, near Rainy lake, Minnesota, and Saline county, 
Nebraska. Moderately abundant in these localities.
