VII.—On Hindeastraea, a New Generic Form of Cretaceous Astraeidae

The little Coral here described was discovered in Kaufman County, Texas, in strata of the Kipley Group, by Dr. R. H. Loughridge, and presented by him to me, together with a few characteristic molluscan species of that group which he found associated with it. The Ripley Group is the uppermost division of the Cretaceous series in the States which border upon the Gulf of Mexico; and probably represents approximately the Upper Chalk of England. Regarding it as a new generic form I herewith give a diagnosis and figures of it; and being the only species known to me, the diagnosis is necessarily based upon this alone.
