In 1888 Charles White made Hindeastraea discoidea the type of a new genus of Cretaceous coral. The type specimen was reported to have been collected from the Ripley (Navarro) formation near Terrell, Kaufman County, Texas. The next year Robert T. Hill reported what he considered to be the same species in the shales at Eagle Ford, Dallas County, Texas. The note was not accompanied by a description, and the corals were referred incorrectly to the genus lsastrea. Although the occurrence of these corals in the Eagle Ford has been known to many collectors other than Hill, there has been no attempt to describe them. The following discussion includes a systematic description of the species, a columnar section showing the stratigraphic position, and speculations concerning the conditions of sedimentation in the upper Eagle Ford.
