It is possible that some of the specimens figured by Johnston , 1 from 
Tasmania, may belong to the species under discussion ; but on account of the 
difficulty of drawing satisfactory conclusions from his figures and descriptions 
it is impossible to institute reliable comparisons. 
The type of frond of T. pinnata is similar to that of T. rotundata, 
Nathorst , 2 and T. rhomboidalis , 3 but the resemblance ends there. T. rotundata 
is a larger, more robust type, and judging from Antevs’ figure, the venation is 
quite different, the secondary veins making a wider angle with the midrib, 
and only forking very occasionally. 
In a recent paper, I referred 4 two specimens from Bexhill, near Lismore, 
to Arber’s genus Microphyllopteris. Those specimens had no trace of the 
venation preserved, and therefore their correct determination was almost 
impossible ; I now suggest that they may be more correctly referred to T. 
pinnata than to Microphyllopteris pectinata. Until better specimens are forth- 
coming from Bexhill, however, it will not be possible to decide this point 
definitely.

T/ENIopteris spatulata, McClelland. 
( T . Daintreei, McCoy.) 
(Frontispiece; Plate II, fig. 9; Plate III, fig. 1 ; Plate VI, fig. 8.) 
The synonymy of this species is long, and has been given in full by Dun 
(98, p. 390), and Seward (04, p. 168). 
The examination of a very large number of Queensland specimens led 
me 5 to consider that there was no reason for separating T. Daintreei, McCoy, 
from T. spatidata, McClelland, and the numerous examples from Talbragar 
afford further confirmation of this. This conclusion had been earlier arrived 
at by Mr. W. S. Dun (see above, p. 4), and had also been suggested by a 
number of European workers in Palseobotany. 
A broad general definition of the species has been given by Seward, 
thus : “ Frond simple, linear, long and narrow, reaching a length of more 
than 7 cm., and varying in breadth from 1-5 mm. to slightly more than 1 cm. 
The apex is either gradually tapered to an acuminate tip or bluntly rounded;
