Description. ''Gaudryina pupoides is an easily recognized 

 species. Its dimorphous mode of growth is generally very ap- 

 parent, and its variability is limited to such features as the num- 

 ber 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 grayish -hue ; fossil specimens sometimes exhibit slightly rough 

 exterior. In form and position the aperture resembles that of 

 the typical Textulariae, but it is often surrounded by a raised 

 tip or border. (Brady.)

Description. "Test elongate, straight, rough externally and 

 arenaceous; early segments triquetrous, spiral, and forming a 

 pointed apex, a transverse section of which is round, not angular 

 as in Clavulina parisiensis d'Orbigny; anterior chambers marked 

 by depressa septa, somewhat irregular in size, but the ultimate 

 one is the largest ; aperture normally a central opening in a short 

 tubular neck of the ultimate chamber. 



"Length, 2.1 mm." (Bagg.)
