Cladoplilebis sp. [Cf. C. [Ehoracia) lobifolia (Phill.) Brgn.] 



Pl. 2, figs. 19, 20. 



The genus Cladophlehis is represented in the Kurremölla 

 flora only by some few imperfect specimens, the best of 

 which are shown in pl. 2, figs. 19 and 20. The specimens 

 consist only of portions of pinnae bearing some ovate- 

 triangular pinnules. In their shape, attachment and venation, 

 these strongly recall those of Cladophlehis {Ehoracia) lohi folia 

 (Phill.) Brgn. As the pinna-bases with the basal pinnules, 

 the peculiar shape of which is the most important character 

 of C. lohijolia, are not preserved, the specimens cannot, how- 

 ever, even provisionally be referred to that species. 



Clathropteris? or Dictyopliyllum ? sp. 



Pl. 3, .fig. 12. 



In pl. 3, fig. 12, is shown, in twice the natural size, a 

 little fragment of a fern- frond belonging to the group of the 

 Dictyopterideae, probably to Clathropteris or Dictyophyllnm. 

 The somewhat square shape of the meshes formed by the 

 anastomosing venation would appear to indicate the former 

 genus, but this character is not very pronounced and the 

 material is too poor to permit of any further conclusion. 

 Some other fragments of the same character occur, but these 

 are of still poorer quality. 



Laccopteris sp. 1. 



Pl. 3, figs. 13—17. 



Some few fragments of fern-pinnules, both fertile and 

 sterile, can be identified as belonging to the genus Laccopteris. 

 They appear to belong to two different forms, but a specific 

 determination is not possible. Those described as no. 1 are 

 figured in pl. 3, figs. 13 — 17. 



The specimens consist only of small portions of pinnules, 

 which measure 3 — 5 mm. in breadth. From the strong mid- 

 rib are given off, at a wide, almost right angle, secondary 

 veins which branch more or less freely. No anastomoses
