Test composed of a subglobular proloculum and long undivided 

 second chamber, at first planispiral like Ammodiscus, but soon leaving 

 the one plane and becoming irregularly coiled ; wall of fine arenaceous 

 material with cement predominating; color reddish or yellowish brown. 



Diameter 0.25-0.40 mm. 



This species in our material shows considerable variation in the 

 material of the test from a nearly purely chitinous wall to one composed 

 largely of fine arenaceous material on a chitinous base. Some of the 

 very smooth thin forms resemble AmTiiodisciis minutissimus in the char- 

 acters of the wall. The species occurs at numerous stations as follows: 

 585, 579, 333, 1046, 2005, 2057, 2037, 2052, 2029, 2065, 253, 510,
