Abstract

A new species of cladoid inadunate crinoid, Endelocrinus kieri sp. n. from the Ames Limestone, Conemaugh Group, Pennsylvanian, is described. The Conemaugh form is closely related to Endelocrinus rectus Moore and Plummer from the Strawn Group of Texas, although more specialized than the Texas species. The retention of ornamented species in Endelocrinus is advocated. The validity of the Strimple genera Tholiacrinus and Graffhamicrinus, which are based on surface ornamentation, is questioned.
