which differed from the former especially by its much larger size, and by 
some other characters. This Indian species was also observed amongst the 
Australian fossils by Mr. Tenison Woods.

“ Frond large, tripinnate ; secondary pinnae somewhat broadly elongate, 
only a little narrowed towards the apex, pinnatisect or pinnatifid ; pinnules 
or lobes rounded at the apex and very thin-leaved ; middle vein (costa) dis- 
tinct, somewhat curved at the apex ; the two lowermost veins divide on 
emerging and join v/itli the similar veins of the adjoining leaflets into a 
pointed arch, while the others are placed more towards the upper portion 
of the pinnules, passing out at a very acute angle from the costa, and are also 
dichotomous and somewhat flexuous.”

Ohs. — The old genus, Tceniopteris, has been greatly subdivided of late 
into various other types, which represent as many different genera, and which 
are all generally included in the family Tacnioptcrideae. The differences of 
the various genera are based upon the different form of the leaves, the 
different mode of venation, the state of fructification, if known, and the 
possible relations with living ferns. According to this, there are distinguished 
by Prof. Scliimper, in ZittcTs “ ITandbuch dor Falaeontologie,” the following 
genera : — Tceniopteris , Brgt. ; Macrotceniopteris , Scliimper ; Talccocittaria, 
Feistrn. ; Oleandridium, Schimp. ; Angiopteridium, Schimp. ; Marattiopsis, 
Schiinp.
