According to Deprat^> and Mansuv,^' Gotlandian strata are developed in 

 eastern Yun-nan and especially in the region lying between the Ki-sha-kiang 

 and Yun-nan-fu, where they recognised the following succession of the rocks 

 (in ascending order) : 



5) Variegated slaty sandstone of Hoang-li-tsuen with OrtJds hour- 



cJiardii Davids. 

 4) Grey sandstone without fossils. 

 3 ) Grey limestone without fossils.

 i) The upper part of the sandstone with Botliriolepis ; its lower part is con- 

 sidered to belong to the Upper Ordovician.
