Br. Slopes — Cretaceous Plant from Nigeria. 435 



Sap. Whatever our Nigerian and Saportu's plants may ultimately 

 prove to be, I think there is little doubt our plant resembles his so 

 closely that, in the present state of our ignorance of the forms, the 

 Nigerian plant should be included in his genus. Therefore I name it 

 in honour of Mr. Kitson, its discoverer. 



Typhacites Kitsoni, n.sp. (Plate XXXIII.) 



Diagnosis of such a species is difficult, but may provisionally be as 

 follows : Impressions, presumably of partly macerated or old leaf- 

 bases of considerable size, i.e. exceeding 4 cm. in width and of indefinite 

 length. The regular meshwork of the surface very coarse, each mesh 

 isodiametric, averaging about 2 mm. in diameter, but in parts 

 narrowing down to 1 X 15 mm.

Drawing of a small portion of the edge of one of the specimens of 

 Typhacites Kitsoni (M. C. Stopes). x 3. 



Types. — The figured specimens are in the British Museum, Natural 

 History. 



Locality. — Azuta River where the Udi Road crosses it, Southern 

 Nigeria. 



Discoverer. — A. E. Kitson, Esq., F.G.S. 



Horizon. — Cretaceous, Middle (?) or Upper, 



Note. — Mr. Kitson authorizes me to state that his large collection 

 of dicotyledons from this and other associated Cretaceous deposits 

 and the Tertiary (?) of other districts in Southern Nigeria is now in 

 the British Museum, and is available for anyone who wishes to 

 describe it. 



EXPLANATION OF PLATE XXXIII. 



Ekj. 1. Specimen of the meshwork of the leaf Typhacites Kitsoni, n.sp. 

 Natural size. 



,, 2. Portion of a similar specimen enlarged by 2 diameters. 



,, ;}. Part of the base of another specimen showing the finer mesh, enlarged 

 by 2 diameters. On the right of the figure are seen the numerous 

 macerated fragments of plants which are abundant in these shales.
