simple, or forking once or twice, and there are never any venules. 

 Some authors thought that the genus may possibly be a Cycad 

 allied to Stangeria, but there are very many objections to this view. 



Tceniopteris daintreei, M'Coy (Paleon., Vict. PI. xv , figs. 1 and 2, 

 p. 15); frond very long, linear, parallel-sided; substance thick, 

 edges straight, costa very strong, veins extending at right angles 

 from the midrib to the lateral margins, a few straight and simple, 

 the greater number once forked at a variable distance between the 

 midrib and lateral margin, total width of frond four lines, about 

 ten or eleven lateral veins in the space of two lines at the margin, 

 both of ordinary specimens, four lines wide, and one specimen 

 nearly two inches long, but only one and a half lines wide through- 

 out. 



This species has been found in two places in Victoria, viz., 

 Murndal on the Wannon river in Western Victoria, and at the 

 Barrabool mills near Geelong. In the latter place it was associa- 

 ted with Alethopteris australis, Morris, and according to Professor 

 M'Coy with Phyllotheca. But I venture to suggest that as the 

 identification of Phyllotheca depended upon the stems alone, with- 

 out the characteristic long linear sheath leaves, it may be doubted 

 whether it was the same species as those of the Newcastle beds. 

 We have seen that the stems of this genus Schizoneura, Equisetum, 

 and other Equisetacea? cannot be distinguished from each other 

 without leaves. It may then be affirmed that Tceniopteris is a 

 plant of the mesozoic flora, and is never found in the Newcastle 

 beds, or associated with any Newcastle or paleozoic plants. 



T. carruthersii, nobis (T. daintreei Carruthers. Proc. Geol. 

 Soc, London, April 1872, p. 355). Frond simple (I), broad linear, 

 costa somewhat thick, veins leaving it at an acute angle, then 

 passing out at right angles to the margin, once or twice dichoto- 

 niously divided. Tivoli coal mine Ipswich, Queensland. 



The venation and general form of this plant differ very much 

 from Professor M'Coy's Tceniopteris daintreei, with which Mr. 

 Carruthers identified it. It is a larger plant and the veins, which 

 are much finer and more numerous, frequently emerge from the 

 midrib obliquely, which they never do in M'Coy's species. Both
