This fern which liad borne the names of Cladopklebis whit- 

 hyensls, Asplenium irJatbyense, Alethophteris whiibyens'is etc. was 

 some years ago pointed out ])y Senyard, as bi-ing closely rehited 

 to tlie recent genus Todea in the nature of its fructification. 



Our specimens are tolerably well preserved in two good- 

 sized slabs of stone, the whole surface of which is covered with 

 tiie ])innie of this fern which, however, are all sterile. The 

 pinnules agree with those of the English specimens as described 

 l\v Hfyyard which, in spite of great variations in shape in dif- 

 ferent jiarts of a frond invariably have the acute apex and 

 twice forked lateial veins. 



This s])ecies occurs in several places in China, as will be 

 seen further on.
