Genus Schizoneura, Schimp. 1844. 



This very peculiar genus was established by Mr. Schimper*. It was 

 formerly known only from the Trias, of which formation it is especially 

 characteristic ; Schimperf having only recently placed the Bha^tic Catamites 

 Soerensis, Hss. J in this genus as Schizoneura Sbrensis, Schimp. ; so that 

 this author can well say (1. c, p. 282), " Le genre Schizoneura characterise 

 le Trias et les couches Mhetique." 



The species of Schizoneura known at present are : — 



Schizoneura paradoxa, Schimp. (1. c), from the Upper Gres Bigarre 



(Lower Trias) in the Vosges. 

 Schizoneura Meriani, Schimp., from the Keuper near . Stuttgart, 



Salz-sur-le-Necker, etc. 

 Schizoneura Soerensis, Schimp., from the Bkaetic at Hoer in Scania, 

 Salzgitter in Hanover, etc. 



This genus is a very characteristic one. It has an articulated stalk or 

 stem ; the originally separate leaflets are grown together into a spathe, which, 

 however, attains a much greater length than the internodes and consequently 

 bursts generally into two pretty equal portions, each containing as many 

 pretty thick ribs as there are leaflets grown together. Owing to the 

 original form of the leaflets (narrower at base and towards the apex), 

 these two portions have an oblong oval shape and are always directed upwards. 

 Sometimes the dehiscence goes further still, so that we find one portion 

 of the spathe only entire and the other split into several leaflets, or even 

 both portions are resolved into leaflets. 



In our Eaniganj group this genus is very abundantly represented, 

 especially at Eaniganj, specimens from which locality have been for many 

 years (16) in the collections of the Geological Survey. But up to date 

 neither figures nor descriptions of it have been published. 



It is simply mentioned as Schizoneura in the Mem. Gr. S. India. 

 Lately § I examined the specimens and found the species identical with 

 that in the Panchet group. I established it therefore as follows : —
