This fragment showing three chambers 

 seems closest to A^ vertebralis by reason of 

 the few continuous ribs and the almost total 

 lack of inflation of the valves. It is common 

 in the lower Midway of Texas but the spe- 

 cies is known to range from the Cretaceous 

 to Recent.

Test elongate, straight; chambers nu- 

 merous; globular, separated by prominent, 

 deeply incised, transverse sutures; ribs 9, 

 raised, fin-like, rarely fused, more frequently 

 abruptly terminated; diameter, 0.8 mm.; 

 length (2 chambers), 0.17 mm. 



The specimen illustrated has been re- 

 ferred to this species because of the joining 

 or fusing of some costae and the termina- 

 tion of others; both features are shown in 

 figure 19. This specimen is classified with 



N. zippei with some hesitancy because all 

 other described forms are from the Cre- 

 taceous.

 Polymorphina cushmani Plummer, 1927, Texas

Test wide, compressed, thickest through 

 rounded base; periphery irregular or asym- 

 metric, rounded on basal margin, produced 

 to point on aperatural end; width, 1.1 mm.; 

 height, 1.2 mm. 



Although the distal end is more rounded 

 than the form illustrated by Plummer, Toul- 

 min (1941) in his three figures and in his re- 

 marks demonstrates the great variability 

 of the outline of this species.

 umbo; diameter, 1.0 mm.; thickness, 0.75
