MADBEPOBABIA APOROSA. 

 Family— ASTRiEID^E. 

 Genus — Thecosmilia. 

 1. Thecosmilia obtusa, UOrbigny, sp. PI. I, figs. 1 — 4. 



The corallum is short. 



The calices sometimes remained united in short series. 



The fossula is shallow. 



Some sixty septa may be counted in the series. The margin of the septa is oblique 

 and delicately toothed ; and their sides are covered with delicate striae, which are radiating 

 and projecting. 



The English locality is in the Great Oolite, Cirencester. MM. Milne-Edwards and Jules

The corallum is massive, and in layers. 



The calices are unequal, not equally distant from each other, circular, and they do not 

 project above the inter-calicular surface generally, but in some instances they form cribri- 

 form projections. 



The costse cover the inter-calicular surfaces, are sub-equal, wavy, and long. 



The septa are very short, and do not reach far into the calice ; there are three cycles 

 in six systems, and the primary septa, which do not project much more than the 

 secondary, are the largest.
