Embryonal vertebrae (probable of Melosaurus uralen- 

 sis [v. Meyer]) have been found in upper Permian sand- 

 stone at the base of the north slope of Saragula hill a- 

 boul 30 miles NE of Orenburg, but the subject of the pre- 

 sent paper is the only labyrinthodont cranium derived 

 from these rocks, which has been brought to my icnow- 

 ledge. 



All the above named strata rest upon a base of lime- 

 stone (magnesian and otherwise) containing Zechstein 

 molluscs and bryozoa, and are hence superior to the 

 middle division of the Permian system as developed in 



Russia and other parts of Europe, while the facies of 

 their fauna and flora excludes them from the Trias. Wher- 

 ever the sandstones are not copper bearing, fossils are 

 wanting.
