CONIOPXEBIS.

Text-fig. 14. 



These two portions of fronds have been drawn from a specimen 

 in Manchester Museum. They agree with the fragment figured 

 hy Phillips as 8. arhuseula, 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 

 ^showu 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 Thyrsopteris 

 Maalciana and the example of Coniopteris Tiymenophylloides repre- 

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

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