In the present paper it is proposed to discuss all of the Theropodous dinosaur specimens contained in the collections of the United States National Museum. The material at hand includes the remains of many individuals, several of which are represented by a considerable part of the skeleton, there are also quite a large number of separate bones.

The present paper proposed to give for the first time a detailed account of the osteological structure of Stegosaurus, to be followed by systematic descriptions of all the type-specimens of that genus and other armored dinosaur remains contained in the United States National Museum collections. With one exception the present work is based entirely upon National Museum material, the exception being a specimen generously loaned by Mr. W. H. Reed, of the University of Wyoming, and described here as a new type species.
