not in Zalessky's collection. Tliey are Annularia sldlald, 

 Neuropter'is flexuosa and Kearopteris Scheuchzerl. 



Zalessky has already arrived at the conclusion that the 

 Yen-tai flora is Stephanian or Upper Carboniferous, and that 

 the occurrence of such forms as Plagiozamites Planchardi and 

 Lepldodendron oculis-felis points to the uppermost part of the 

 above named stuge. The newly found Annularia slellaia which 

 ranges between Westphalian or Middle Carboniferous and Permian 

 greatly favours this view ; while the two forms of Neurojyleris, JV. 

 ßexuosa and Ji. Scheuchzerl which are both found in the West- 

 phalian as well as in the Stephanian, but do not go higher than 

 the lower part of the latter, seem not in perfect harmony with 

 it. But it must be remembered that our materials were obtained 

 from the waste scattered near the mouth of the shaft, and it is 

 not known whether they belong to the same horizon as those of 

 Zalessky, or even, whether they are from a single horizon or 

 not. The presence of the yellowish plant-bearing sandstone above 

 mentioned shows that there are at least two such horizons. 

 Under these circumstances, I deem it advisable at present to 

 consider our plants as simply Stephanian.
