It seemed not unlikely that the species of Orion-astfcea and Aulina described by the Author would provide a meansof more precise subdivision and correlation of the highest beds ofthe Lower Carboniferous, and the speaker would be glad to hearmore about the distribution of these corals. He hoped that theAuthors researches would be continued, and extended to Devoniancorals as well as to other Carboniferous types. Mr. C. B. Wedd remarked upon the interest of these corals anappearing at very high horizons of the Carboniferous LimestoneSeries, and presumably at the highest coralliferous horizon in theCarboniferous of this country. He compared the coral-sequencesuggested by these forms to that of Central Russia, where
