Thinnfeldia media , Tcnison Woods, Joe. cif., 1S33, pp. 102, 103, PI. G, f. 1. 
Ohs. — Mr. Tcnison Woods compares it with Thinnfeldia indicci , 
although, as far as can he judged from the figure, the relation appears to me 
very small. 
Locality and Horizon. — Found in the sandstones at Duhbo, New South 
Wales, where it is associated with Thinnfeldia odonlopteroides. Tcnison 
Woods considers these sandstones to he the same as the llawkesbury Sandstone 
(Mesozoic) ; also at Spring Hill, Tasmania. 
Gen ns— ODONTOPTERIS, Brongniart. 
Ohs. — In the same family with Thinnfeldia used also to be placed the 
genus Odontopteris ; but, while Thinnfeldia is now classed with the Lomatop- 
teridese, Odontopteris is the type of a special family. Odontopteris is believed 
to be especially a Carboniferous fossil, but the present form from Australia is 
from a higher horizon.

obtusely elliptical, their length equalling the width of their base, no midrib; 
secondary venation indistinct.”
