So long ago as 1897 Baron Franz recorded the discovery of numerous bones of Dinosaurs and Chelonians in fresh water deposits of Upper Cretaceous age at Szentpeterfalva in Transsylvania. Since that time he has made extensive collections of bones from the same locality and has published various papers concerning them. In his last collection, now in the British Museum (Natural History), there occur some fragments of limb-bones which he does not consider to be reptilian but rather of avian origin. These specimens he has kindly submitted to me for determination and description, and they form the subject of the present paper.
