Corallum forming large masses; corallites subcylindrical, 

 somewhat tortuous, spaced one to two diameters distant ; epi- 

 theca wrinkled, thick; septa obsolete; tabuhe very numerous, 

 somewhat funnel-shaped, often forming a tube down the center 

 of the corallite, running into each other laterally, forming vesi- 

 cles. Size of corallum unknown, specimens eighteen inches 

 in diameter appearing incomplete on all sides. Connecting 

 tubules numerous and irregularly placed. The diameter of the 

 corallites varies from 3 by 1-J- to 2 by 2 mm. 



Range and distribution : Upper Coal Measures ; Atchison, Le- 

 compton, Lyndon, Osage county.

Corallum large, massive, somewhat globose; corallites very 

 closely arranged, very long, same size throughout the entire 

 length ; walls thin, roughly five- to seven-sided, one diameter 

 usually longer than the other ; average diameter about a third 

 of a millimeter. Tabuhe about a third to a seventh of a milli- 

 metei distant, horizontal, not always uniform throughout the 

 group. 



Range and distribution : Coal Measures, Girard ; very abun- 

 dant in the Oswego limestone, in which they form large masses. 



Specimens of this species often attain a very large size. Some 

 from the Oswego limestone are thirty inches in diameter, and 

 still appear to be incomplete.
