GLOSSOPTERIS. 85 



The imperfect specimen with a very oblique nervation figured 

 by Tate ' in 1867 as Dictyopteris (?) simplex, may be compared with 

 this species as regards the characters of the meshes. A re- 

 examination of the type, preserved in the Museum of the Geological 

 Society of London (No. R. 11,104), has shown that it is probably 

 a frond of Glossopteris, but that the fossil is too fragmentary to 

 permit of specific determination.
