A. decaturensis (7) 
Locality : Hale’s Landing, 7 miles belovv B&ihbridge , Flint 
River, Decatur County, Georgia* T . ¥. Vaughan, Collector® 
Ge clog 1 c ho r i z on : Upper Oligccene, Bainbridge chert. 
Type : United States National Museum* 
Remarks : The septal arrangement in this species is very 
similar to that of Porita s in the presence of a plane of symmetry 
and the tendency of the septa to fuse by their inner ends in 
pairs# The septa themselves, however, are very different, being 
lamellate, almost imperforate, and sharply differentiated from 
the surrounding coenenchyma* 
Unfortunately the calices of A * b ar t o lonae i are not pre- 
served, and thin sections did not prove so satief actory as was 
wished* 
Prof, Pelix in his "Anthozoen der Gosauschichtan in den 
Ostalpen” has redescribed and figured A, haueri Reuss and A. 
Palaeontographioa, Bd* XLIX, pp . 178-178, figs. 2,3,
