sepiment numerous in the central 3/5 of the corallites, almost hori- 

 zontal; peripheral part with vesicular endotheca, composed of numerous, 

 oblique, semilunular vesicles arranged in three or more rows. 



Obs. : — According to F. Frech, Spongophyllum scdgivicki M. Ed. et 

 H. comprises two quite different forms ; one a true Endophyllunt sedgiuicki M. 

 Ed. et H. (emend Frech) and the other a true Cyathopliyllum {C. doiivillei 

 Frech). It is the latter which shows undeniable affinity to our specimen. 

 They are essentially so similar as to leave no doubt about their specific iden- 

 tity, only a slight difference being recognisable in the outline of the corallites 

 and in the relative breadth of their central and peripheral parts. The corallites 

 of our specimen are not only more irregular and more varied in the outline than 

 those of figured by M. Edwards, J. Haime, F. Frech and H. Mansuy, but 

 have the peripheral part decidedly narrower in relation to the central 

 part. On account of these slight differences we tend to regard our specimen 

 at most as a variety of the Devonian coral already found from Torquay (Eng- 

 land), Nismes (Belgium), and Ta-i-ti (southern Yiin-nan). 



Locality : — Yang-liu-shu, Ta-kuan-ting, prov. Yun-nan, China. Found in 

 association with Favosites asteriscus Frech. 



Geological Age ; — Middle Devonian.
