Mooreocrinus and Ureocrinus gen. nov., with Notes on the family Cromyocrinidae

In the course of discussions on Echinoderms between the senior and junior authors, the family Cromyocrinidae came under scrutiny and in view of a vital link of evidence in the form of a Pennsylvanian (Upper Carboniferous) specimen of Ulocrinus buttsi Miller and Gurley with the arms attached, found by the junior author a few years ago, the following interpretation of the family is suggested.
