Bull., vm, 1904, p. 57. The type and only known specimen belongs to the University of Texas. It was discovered by Professor Cope in the year 1892, in the Blanco beds of the Pliocene, near Mount Blanco, Crosby County, Texas. Ot this species the writer found in the University of Texas only three or four large fragments which had been glued to sheets of paper. These fragments may or may not belong to the type. The thickened por- tions of the anterior and posterior lobes of the plastron appear not to have been preserved. It seems probable that the type was injured before being returned to the collection at Austin. Under the circumstances, nothing more can be done than to republish Cope's description and his apparently more or less diagrammatic illus- tration (fig. 609). In this figure, 1 represents the carapace and part of the front of the plas- tron seen from above. The other part of the figure, 2, shows the hinder lobe of the plastron as seen from above. Founded on a large specimen measuring three and a half feet in length by three in width, and re- markable for the transverse width of the vertebral dermal scuta. The carapace is rather flat and descends steeply posteriorly, the anal marginal bone being somewhat incurved. Margins of carapace flare outwards above the legs. The plastron has a rather wide lip, with flat base and straight lateral borders; its anterior border is lost. The posterior lobe is deeply and widely notched, terminating on each side in a subequilateral angular prominence. Both cara- pace and plastron are without sculpture, the poste- rior angles of the plastr
