 genera Thcca, OrtJiis, Lijigulclla (two species), Agiwstiis, Coiioccphalitcs, 

 CrcpiccpJialus, and ? Riiiuioplciiridcs, and correlates the formation with that 

 of the Andrarum limestone of Scandinavia." 



"In 1899 M. Bergeron^' described the following Cambrian fossils from 

 shaly limestones collected in the Province of Shan-tung'\ China : 



Agiioitus douvillei Artliricoccplialus cJimivcani 



Olcnoidcs Icblanci DicclloccpJialiis ? sincnsis^'^ 



IDrepanura prcmcsidli Calymcnc ? sinensis'"'' 



"In 1903, H. Monke''* published a paper on the Geology of Shan-tung 

 and described certain '' Upper Cambian " trilobites, as follows : 

 Agnosiwi kocrfcri Drcpaimra kcttclcri 



Liostracina krajisci . SicpJiaiiocarc richtJiofou 



Tcinistion land S. sinciisc 



T. sodcni 5*. sp. ? " 



Drcpanura prcmcsnili 



" In 1904, Til. LoRENz described some problematical fossils as Algae 

 under the new family Ascosomaceae of the Siphoneae^'. The genus Ascosonia 

 was proposed to include one species, Ascosovia phancroporata, and a second 

 species was placed under a new genus as MitscJicrlicJua chincnsis.'' 



" In 1905, some of the results of the Carnegie Institution of Washington's 

 Expedition to China were published by the writer", and a second paper ap- 

 peared in 1906**'. These two papers included descriptions and certain intro- 

 ductory notes on the Cambrian fossils collected by Messrs B. Willis and E. 

 Black WELDER."
