Remarks. — In my earlier papers I treated Alethopteris decurrens, Artis, sp., as a 

 variety of Alethopteris lonchitica. This I now believe to have been an error. The two 

 plants are easily distinguished by their nervation, and, when once understood, cannot 

 easily be mistaken with each other. Alethopteris lonchitica is extremely common in the 

 Lower and Middle Coal Measures, but very rare in the Upper Coal Measures. The 

 plant is so common in the Ayrshire Coal Measures, that care has not been taken 

 to record its occurrence at the various localities where it has been found, hence the 

 small list of definite records.
