5. Huang-chia-chang/' Tung-hu-hsien,^' prov. Hupei (Noda Coll. No. 

 122); a grey limestone with abundant fragments of 



Batostoviclla antiqiia Yabe 



6. San-yu-tung,'' near I-chang, Tung-hu-hsien, prov. Hu-pei (Yamada 

 and FuKUCHi) ; a dark grey, sapropelic limestone with numerous pseudo- 

 oolites which are composed of filaments of 



Girvanella sinensis Yabe 

 On a former occasion, I took this limestone to be of Carboniferous age, 

 following Willis and Blackwelder ; the locality is, however, included in an 

 Ordovician area by Noda. Since the same form of Girva)iella is found in an 

 Ordovician limestone from Liu-chia-ho, mentioned above, the present speci- 

 men is also assigned to Ordovician.

 limestones, which are mostly grey in colour and earthy in texture, being rare- 

 ly crystalline :
