the place, are contained in a dark-grey isli, micaceous, shaly 

 sandstone, having a slight purplish tint. They are very numerous, 

 but all belong to the single species of Cordaites lorincipalis Germ. 

 From tbis, I can only infer that the age is either Westphalian 

 or, more j^i'obably, Stephanian. But it is also not impossible that 

 the plant-bed is Permo-Carboniferous, as the above species also 

 occurs at Pen-hsi-hu.

Prof. Yamasaki of the Tokyo Higher Normal School who 

 visited China in 1905 brought from the above place a piece of a 

 light grey to whitish, micaceous, fine-grained, platy sandstone and 

 several small pieces of weathered shales, in the former of which 

 there is an impression of the so-called Knorria Sellonii Sternb. 

 In the shales there are many indistinct remains of leaf-fragments, 

 among which I believe I discern a species of a Pecopteris-Vike, 

 fern, which is however quite indeterminable. 



As Knorria is now generally acknowledged to be only a 

 state of subepidermal preservation of lepidodendroid plants such 

 as Lepidodendrons and Bothrodendrons, the age of the fossil can 

 only be said to be Palaeozoic from Devonian upward.
