CONIOPIEKIS. 115 



Text-fig. 14. 



These two portions of fronds have been drawn from a specimen 

 in Manchester Museum. They agree with the fragment figured 

 by Phillips as S. arbuscula, var. A few portions of sterile pinnae 

 which occur on the same piece of rock probably belong to this 

 species. 



Other specimens : V. 3291 (similar to the Manchester specimen 

 shown in Text-fig. 14), V. 3678, 10,317, 39,267 (cf. Text-fig. 15), 

 52,568 (this is similar to the fronds named by Heer Thyrsopterit 

 Maakiana and the example of Coniopteris hymenophylloides repre- 

 sented in PI. XX. Fig. 1 ; but the pinnules are farther apart, 

 and the general habit of the frond is more open). 



3. Coniopteris arguta (Lindley & Hutton).
