CHAPTER I. 

 Cambrian. 



The extensive investigation of Cambrian fossils by Cii. D. Walcot l' is one 

 of the foremost palaeontological works that lias yet appeared. The Cambrian 

 fossils of China have also of late been studied by him and in consequence our 

 knowledge in this respect has made great progress. 



His " The Cambrian Faunas of China " (Research in China, vol. III. 

 1913) contains an excellent summary of the works of previous authors in the 

 same field. From it we quote the following : — 



" The presence of Cambrain fossils in China was first announced by 

 Baron v. Richthofen in 1883^'. The material gathered by him was studied 

 by E. Kayser to whom the brachiopods-' were entrusted, and by W. Dames, 

 who described the trilobites^^ 



" Kayser described and named the following brachiopods : OrtJiis liii- 

 narsonf^ ; Lingulclla sp.; L. sp." 



" Dames described and named the following trilobites : 



Agiiostiis chinoisis Aiioinocarc inhiiis
