Description. — Test composed of a subglobular proloculum and 

 long, undivided second chamber, winding upon itself in various 

 planes, not completely spiral throughout, wall finely arenaceous, with 

 a predominance of cement, smooth both without and within, color 

 reddish or yellowish brown. 



From the original references, Glomospira Rzehak must be used for 

 this genus instead of Gordiammina Rhumbler. There are two recent 

 species.
