N. S. Wales, p. 115, pi. xxviii., fig. 7. 



Frond simple, strong midrib from which numerous single or forked 

 secondary veins are given off either at right angles or at a wide 

 angle. The breadth of the lamina decreases gradually towards the 

 petiole. 



In 1872 Carruthers '■' referred some TcEniopteris leaves from 

 Queensland to McCoy's species T. daintreei,] but as Tenison- 

 Woods pointed out in 1883, McCoy's type is characterised by the 

 narrow linear form of the frond and differs considerably from the 

 broader form of leaf figured by Carruthers. The specimen described 

 by Carruthers [in the British Museum Collection (V. 4199)] is clearly 

 identical with those from South Africa figured by Feistmantel. A 

 leaf from the Argentine named by Geinitz Tcenioptcris mareyiaca,l 

 bears a close resemblance to T. carruthcrsi, but there appears to be 

 a slight difference in the venation. Some specimens from India 

 referred by Feistmantel to Tcenioptcris vittata,%, a species differing 

 but slightly from T. carruthersi, are very similar to the type of 

 frond shown in pi. viii., fig. 6. A Ehastic species from Scania, 

 named by Nathorst Tcenioptcris i'inmcrsa,\\ may be identical with the 

 South African fern ; but the comparison of sterile fragments of 

 Tczniopteris fronds can lead to no certain results. 



Plate VIII., fig. 6 (497d). 



Portion of leaf 8'5 cm. long and 3 cm. broad ; the midrib is com- 

 paratively broad and well defined. The secondary veins are approxi- 

 mately 1 mm. apart or slightly closer. 



Plate VIII., fig. 5 (14e). 

 This much narrower fragment is distinguished by the more open 

 arrangement of the forked and simple lateral veins, but it may
