 According to Frech,^^ the British Museum further possesses some speci- 

 mens of other Upper Ordovlcian fossils, 

 Troclioccras sp. and 

 Acfiiiocc/'os sp., 



derived from a locality in Shan-tung which is not exactly known. 

 The same author''^ also described 



Acfiiioco-as ricJitliofcid Frech, and 

 Rapliistoma cfr. acqiiilatcnim Kokkn 

 which were collected by Richthofen at Hsiau-sorr along the Ta-tse-ho^^ in 

 Manchuria ; they likewise represent the Upper Ordovician. Nautiloids with 

 the same features as those mentioned above are rather common in the 

 Ordovician limestone of southern Manchuria and northern Korea. 



Further discoveries of Ordovician fossils in Shan-tung are as follows :
