1. ANGIOPTERIDIUM CFR. INFARCTUM 1 eistm. 

 PI. II. Fig-. 2. 



Two frasjraeiits of oblonsf-linear entire leaves. The one which 

 has been figured measures about IC mm. in breadth, pierced by 

 a moderately strong, straight midrib. Although the secondary 

 veins are mostly defaced, yet by a proper illumination, we can 

 observe that they are very fine and dense, similar in their course 

 to those of the above named species. 



2. CLATHROPTERIS sp. 



PI. II. Fig. ;i 



On a piece of stone, ^ve see fragments of two broad laminae 

 of a fern apparently partly overlapping each other. One of these 

 laminae shows a distinct, but weak straight midrib which gives 

 off at regular intervals straight secondary veins at angles of from 

 45"^ to 50"^. They are mostly opposite or subopposite, but some- 

 times alternate. We have probably here to do with a species of 

 Claihropteri^, a genus widely distributed in the Rhœtic formation 

 of several countries.
