HJ. MÖLLER AND T. G. HALLE, FOSSIL FLORS OF S.E. SCANIA. 29 



In his first communication on the plant-remains from 

 Kurremölla, Nathorst (1. c.) noted the presence of a,Ctenis, 

 not very different from C. falcata Lindl. This plant is very 

 common at Kurremölla, its remains sometimes quite covering 

 the bedding planes. All the specimens are very fragmentary, 

 however, and do not permit of a specific identification. 



The best specimens are shown in pi. 5, figs. 8 — 10. Like 

 all the others, they consist only of portions of detached 

 pinnae. The shape of the latter cannot be ascertained, but 

 they appear to have been linear with fairly abruptly tapered 

 apices. The largest fragments (figs. 9 and 10) have a breadth 

 of about 20 mm , the others are somewhat narrower. The 

 venation is distinct and shows the anastomoses characteristic 

 of the genus. There is some variation in regard to the 

 closeness of the venation, the average distance between the 

 veins varying from 0,7.5 mm. to 1,5 mm. In the fragment 

 shown in fig. 9, the veins are fairly distant, with very few 

 anastomoces, and remarkably parallel. 



The genus is represented in the coal-bearing deposits of 

 N.W. Scania by C. jallax Nathorst.^ From that species 

 the present fragments differ, however, in having considerably 

 denser veins. The undescribed specimens from Hör approach 

 somewhat the Kurremölla form, but even these have a coarser 

 venation. Raciborski- has described from the supposed 

 Middle Jurassic of Poland not less than six species, a couple 

 of which (especiall}'^ the specimen in his pi. 16) fairly closely 

 resemble the Kurremölla specimens. No identification with 

 any of them can be attempted, however. The English type 

 species, C. falcata Lindl. ^, is also, as already remarked by 

 Nathorst, somewhat similar to the present specimens, but 

 it has narrower pinnae and cannot be specifically identical 

 with the Kurremölla form.
