VOL. XXXV. 



All the sulci of the plastron, as of the carapace, occupy broad 

 grooves. The gulars were 37 mm. wide in front and they overlap 



slightly the entoplastron. The hu- 

 mero-pectoral sulcus crossed the 

 plastron just behind the entoplas- 

 tron. The numerals occupy 28 mm. 

 of the midline; the pectorals, 25 

 mm. ; the abdominals, 61 mm. ; the 

 femorals, 40 mm. The length of 

 the anals can not be satisfactorily 

 determined. 



This species resembled most of 

 all Cope's Emys lativertebralis, 

 described from the Wasatch of New 

 Mexico. The latter species had, 

 however, both the neurals and the 

 vertebral scutes relatively wider. 

 The carapace and the plastron were 

 not channeled along the course of 

 the sulci. The epiplastral lip did 

 not project so abruptly from the 

 anterior lobe of the plastron and 

 the hinder lobe was not conspicu- 

 ously notched at the sides. The entoplastra of the two species differ 

 in form. 



TERRAPENE LONGINSUL-ffi, new species 



Plate XXVI, figs. 1-3. 



This species has as its type and only known specimen a nearly com- 

 plete shell, the skull complete, the neck, the right and left scapula? and 

 coracoids, and both humeri. This specimen was collected in 1884 by 

 Mr. J. B. Hatcher at Long Island, Phillips County, Kansas. The 

 deposits are regarded as belonging to the Upper Miocene or Lower 

 Pliocene. Mr. J. W. Gidley, of the U. S. National Museum, informs 

 me that these beds have afforded remains of the short-legged rhi- 

 noceros, Teleoceras fossigcr. The new species is accompanied by por- 

 tions, including the characteristic epiplastral beak, of the turtle Tes- 

 tudo orthopygia, which occurs so abundantly in Decatur County. 

 The white siliceous sand that adheres to the bones of the Testudo is 

 identical with that filling the shell of the Terrapene. 



The specimen is Cat. No. 5983 in the U. S. National Museum. 



This species had a broad and rather depressed carapace. Its length 

 (Plate XXVI, fig. 1) in a direct line is 133 mm. ; the width at the hinder
