and arranged in parallel bands."* The upper beds are "dark red, purple, 

 and brown." Judging from the somewhat meager descriptions, the 

 lower part of the "desert sandstone" closely resembles the Moencopie 

 formation. It seems not improbable that both sets of strata were depos- 

 ited under the changing climatic conditions of the Permian strophe, and 

 that both owe their peculiar ■ character to the fact that they were formed 

 in large desert basins of the same type as those of Lop and Seyistan. If 

 this interpretation shall prove correct, it may be found that the records 

 of the Permian strophe are as complete and as remarkable to the north 

 of the equator as to the south.
