Ohs. This is a larger plant than the original T. Daintreei of McCoy, and the 
general form is different. The veins, instead of leaving the midrib direct at right 
angles, as in the case of the species named, pass from it at first obliquely, and then 
assume a similar course to the former. These points were used by the Kev. J. E. T. 
Woods for the separation of this plant from T. Daintreei, McCoy. 
It is, however, but due to Prof. Sir E. McCoy to state that he appears to have 
been the first to point out * * * § the difference between the two species, an opinion in which 
he was supported on three separate occasions by Dr. Peistmantel.t I point this out 
because the Rev. Mr. Woods appears to have ascribed this matter to the latter observer, 
although it is of course possible that Dr. Peistmantel may have independently arrived 
at such a conclusion. The great width of the frond, and the compai’atively narrow 
midrib are striking features in this species, and should, with the venation, always serve 
to distinguish it. It should be distinctly borne in mind that veins leave the midrib at 
an acute angle, and then inmediatcly proceed towards the margins horizontally, or at 
right angles, like those of T. Daintreei. At least this is Mr. Woods’ statement, but I 
would observe that in Mr. Carruthers’ figure the veins do not diverge at a right angle 
after leaving the midrib, but at one rather more acute than this, although less than 
that by which they at first issue from the midrib. 
Tesoniopteris Carruthersi is remarkably like Angiopferidinm Maclellandi, Old. 
and Morris, J and seems only to possess a wider frond and thicker midrib. 
The Geological Survey Collection contains a single leaflet from the Stewart’s 
Creek Beds which partakes in part of the characters of both the species, and I am quite at 
a loss to which to refer it. The specimen possesses the form of T. Carruthersi, and the 
more numerous and widely diverging veins of A. Macclellandi, but I have provisionally 
referred it to the former, 
In PL 16, fig. 4, we have a large TcBniopteris, at present undetermined, and 
unfortunately a single specimen. The veins have been drawn as anastomosing, but in 
reality this is not the case, they simply fork. The leaflet is too large, and the veins 
too close together for A. spathulatum, neither does it correspond with T. Carru- 
thersi. Mr. Kidston suggested a reference to A. Macclellandi, relying on Zeiller’s 
figure of the plant from Tonkin, § but this does not correspond with the original 
illustration of Oldham and Morris. The specimen must for the present remain 
unnamed.
