Dr. Walcott has correlated this formation with the Chaumitien limestone of 

 the Chang-hia region and referred it to the lower part of that formation, but with oi.ir 

 present faunal evidence this formation is recognized as younger than the Chaumitien 

 limestone and should be given a separate name. 



Ptychaspij^ suhglohnRn Gi'obau also occurs in the same character of limestone 

 (limestone conglomerate) of the Fengshan formation. Mansuyia orientalis (Grabau) 

 Sun is also the most common species in tliat formation. The succession of the strata and 

 the paleontology clearly indicates that this formation is the equivalent of Fengshan 

 limestone of (Dhihli, and certainly belongs to the upper part of the Upper Cambrian. 



Aqnostus cijclriiii/gcfnriiris Sun is very closely related to the European form A. 

 cyclnjnjge of Sweden. This indicates that the Upper Cambrian sea of China had a close 

 connection with that of Europe. That is why many Chinese and European forms appear 

 to be identical. 



Pti/cJiaf^pis angidata Mansuy is found al)nndantly in the Upper part of the Upper 

 Cambrian of Tonking, it is also present in this formation. Hence this formation is 

 equivalent to Pfychaspis angvlaia zone of Indo-China. 



The discovery of the neAV genus (^andraticephalus of the family Dikelocephalinse 

 which comprises the characteristic form of the Upper Caml)rian of North America is of 

 considerable interest and significance.
