According to Usui, the fossiliferous horizon of No-lu-ping is followed 

 higher up by another which is well exposed on Mt. Lo-ling-po'^ near No-lu-

 as will be mentioned later on. All these older Palaeozoic rocks are then 

 overlaid by a complex of Permian age.

 Hu-pei (Y. ISHii Coll.) ; in a reddish mottled crinoidal limestone :

 to Ordovician ; but such an assignment seems highly probable.
