There are found associated with the remains of the genus _Sauropleura_ a number of heavy scutes or scales. There are three of them on the same block as the specimen of _S. longidentata_ and are provisionally referred to the genus. There are a number of scutes preserved separately, but they agree in their characters with those discovered on the specimens. The scutes are elongate and usually acuminate at one end and having a broad base at the other. The acuminate end is slightly bent to one side so as to present the appearance of a hook. Others are shield-shaped and are quite large, while the majority of the hook-shaped ones are small. The shield-shaped elements have a rounded boss near the center of the plate and the edges are imbricated. Their nature and their proper location on the animal are a puzzle. They may not belong to the genus, but have been noticed with the remains of at least 3 species. Measurements (in Millimeters) of Scutes Associated with the Specimens of Sauropleura. No. 4513 U. S.
