The tVoml is ])innatc. The pinnules or segments are alter- 

 nate, elongated, somewhat inclined forward, slightly overlapping, 

 mostly 2^arallel-sided, hut slightly narrowed at hase, and attached 

 laterally to a straight racliis which is longitudinally striated. The 

 length ot the ])inuulcs is not known, as they are not wholly 

 preserved, ])ut the hreadth in one of them is l>5 mm. which 

 diminishes to '20 mm. at base. The stem or racliis is straight 

 and measures 10 mm. in hreadth. The veins ai-e numerous, 

 l)arallel, about 10-12 in the s})ace of a centimeter measured across 

 the segment, often dichotomizing and also uniting so as to form 

 an elongated mesh. 



The only specimen which we possess is incomplete as may 

 be seen from the figure, but the above given characters sufficiently 

 show that the plants belong to a form hitherto undescribed. In 

 the size of the segments and the fineness of the venation, it re- 

 sembles Ctenu Zeuschneri Raciborski (Flora kopalna ogniotrwalyk 

 glinek krakowskich, czesc 1, Archegoniatie, p. GO, pi. XVI) from 

 the Polish Jurassic, but in the former the basal portion of the 

 segments is much more abruptly Jiarrowed than in the latter.
