new locality. Its real significance, however, is not quite clear to us, and ' 

 hence we find ourselves justified temporally in following Frech in putting the- 

 species in the genus Favositcs. 



Frfxh mentioned that the transluscent star-like thickening of the wall 

 occurs only where four or more frequently five corallites come in contact, but . 

 never in the case of three (cfr. PI. IX., fig. 2a in Richthofen's China vol. 

 v.). We found, however, rather frequent examples of this in our specimen ;. 

 such slight difference being of course of no importance for the specific demar- 

 cation, we refer our specimen to the named species. 



Locality and Geological Age : — Frech found this species from the Middle 

 Devonian of Hwa-ling-pu, prov. Sze-chuan ; the single specimen at our diposal 

 was collected by Prof K. Yamada of Kyoto Imperial University, at Yang-liu- 

 shu, Ta-kuan-ting, prov. Yun-nan, in association with CyathopJiyllinn Dou- 

 villei Frech. This association confirms the view of Frech regarding the. 

 geological age of the coral limestone with F. asterisais of Hwa-ling-pu.

It is not our present purpose to recapitulate in this place the discussion 

 concerning the much disputed problem refering to the specific identity or dis- 

 tinction of the Devonian F. goldfussi and the Silurian F. gotlaiidicus. As a 

 matter of fact, the slight difference of corallum in general form, of corallites in 

 average size, of mural pores in distribution, of septal spines in development, 

 as mentioned by M.-Edwards and Haime,'> Roemer,*^ Frech^' and Gltrich,^' 

 are in fact not seldom found insufficient for their separation, so that there are 

 still many followers of Nicholson's^* view.
