Type-specimen. Newcastle-upon-Tyne Museum.' The available- 

 material is insufficient to enable us to give a satisfactory diagnosis- 

 of the species. The fi'ond was probably bipinnate ; the large, 

 broadly linear pinnules have the Cladophlebis tj'pe of venation ; 

 they are attached at almost a right angle, and diJEEer from those- 

 of C. denticulata in being straighter and not falcate. There are- 

 no specimens in the British Museum Collection which can be- 

 reasonably referred to this species. A solitary example in the 

 Leckenby Collection, Cambridge (No. 80), agrees exactly with 

 the specimen figured by Lindley & Hutton. It is possible that 

 Cladophlehis haibvrnensis is not a distinct species, but the general 

 appearance of the Leckenby specimen hardly favours its inclusion 

 in any of the other species of Cladophlehis or in Todites Williamsoni. 

 There is a striking similarity between C. haiburnensis and a specimen 

 named by Heer Asplenium whitbiense tenue.^
