Frech, the Middle Devonian limes .one covers an extensive area about i8o— 

 200 km. from north to south, extending from Heng-shan,^' along the Hsiang- 

 kiang, far southward beyond the border of the province of Kwan-tung into its 

 interior. The limestone is grey to black in colour, strongly folded, and 

 forms in itself a thick complex ; it is overlaid apparently concordantly by 

 quartzose rocks and compact sandstones. The limestone was found by 

 Oemichen to be most fossiliferous in an area of about 60 km. radius around 

 -Kiang-hwa^' in southern Hu-nan ; the fossils are, according to Frech : — 

 Syringopora sp.

Most of his specimens, however, are so imperfect that it seems to me 

 almost unreasonable to assign them to any definite species. The figures 

 on PI. XXVII. (figs. S, 9 a-b, 10) are copies of those given by Frech in his 

 paper, and represent the specimens referred by him to Bcllcrophon striatus

Finally it should be mentioned that Martelli and Pellizzari described 

 certain Upper Devonian fossils from the province of Shen-si ; they are :
