36 THE PALEONTOLOGY OF MINNESOTA. 
(Lagena, Nodosaria. 
The arched part of the shell is very variable in form, sometimes nearly circular, 
almost egg-shaped or even narrow and long-elliptic, very near cylindriform. To- 
wards the top it is drawn out into a thin tubular beak, which embraces half the 
length of the shell. The surface is covered with irregularly disposed, but crowded 
shorter and longer, thicker and thinner, variously shaped thorny tubercles. In some 
examples, especially the narrow-elliptical ones, the tubercles are very small and 
contracted into short monticules.
