Cyrtoceras {Meloceras) asiaticum Yabe 

 Grabau' identified a specimen of Actinoceras figured by Yabe^ from No-lu- 

 ping, Hu-hsi, Hsing-shan-hsien as Actinoceras coulingi Grabau, 



c. At No-lu-ping, Tung-hu-hsien, S. Usui' found some cephalopods in the lime- 

 stone, grey in colour and earthy in texture, which is directly overlain by the 

 Silurian deposits. From the stratigraphical point of view the fossiliferous 

 horizon of No-lu-ping seems without doubt to be the Neichiashan forma- 

 tion.
