FOSSILS FROM KANSAS-OKLAHOMA RED- BEDS 339 



2. Two miles northeast of Orlando, numerous vertebrates. 



3. Cedar Hill and Bitter Creek, northeast of Watonga ; inver- 

 tebrates. 



4. Whitehorse Spring, sixteen miles west of Alva; numerous 

 invertebrates. 



Of these localities those numbered I and 2 are from the lower 

 part of the Red-beds, not far from the base of the Harper sand- 

 stone. The fossils from locality numbered 3 were taken from 

 ledges of sandy dolomite immediately beneath the heavy ledges 

 of gypsum found near the middle of the Red-beds. Locality 

 numbered 4 is from the Red Bluff sandstone in the upper part 

 of the series. 



A large vertebrate from McCann's quarry, or locality 1, was 

 identified by Dr. S. W. Williston as Eryops megacephalons Cope, 

 a form characteristic of the Permian of Texas. The invertebrates 

 from the same locality were sent to T. Rupert Jones, who classi- 

 fied them as Estheria minnta, a Triassic form. The plants were 

 shown to Dr. Lester F. Ward, who said that the forms seemed 

 to resemble Mesozoic rather than Paleozoic types. From the 

 Orlando locality Dr. Williston has identified the following 

 forms : Diplocaulus magnicornis Cope ; Diadectidce Gen. indt.; Pari- 

 otichns i?icisivorus (?) Cope; Labyri?ithodont ; and Trimeror- 

 hachis ; all of which he recognizes as Permian forms. From the 

 locality numbered 3 but one species has been found. This is an 

 invertebrate which here occurs in great numbers, and has been 

 referred by Dr. J. W. Beede with some doubt to the Permian 

 form Sedgwickia. The Whitehorse locality has yielded some 

 twenty species of invertebrates, several of which are of new 

 forms. 



This locality is from the upper part of the Red-beds, or to 

 be more exact from Cragin's Red Bluff sandstone perhaps 150 

 feet above the Medicine Lodge gypsum. The following genera 

 are represented : Conocardium, Aviculopecte?i ) Schisodus, Pleuro- 

 phorns, Bakevalia, Naticipsis, Pleurotomaria, Ortho?iema and Mur- 

 chisonia. One form that was at first thought to be Jagmayeria, a 

 shell of Triassic age, has since been identified as Dielasma, very
