In PI 17, fig. 7, is a fern, tie right-hand pinnules of which agree with those of 
T. odontopferoides, whilst those on the left agree better with those of T. media. Ten. 
"Woods, or even the Y&v.falcata, and seems to represent a transition form between the 
two species (?). 
In his Memoir on the Australian Coal Plora, Mr. Tenison Woods mentioned, 
amongst the fossils of the Ipswich Basin, Thinnfeldia australis, but he does not describe 
such a species. 
Loc. New Chum, Bundanba, Ipswich Basin, 170 ft. below New Chum Upper Seam, 
PI. 17, f. 1 (U. C. Ringrose) ; Eedbank, near Mount Esk, Brisbane Eiver, north of 
Laidley (JV. Souttar); Kilcoy Eango, above Cressbrook {TF, Souttar')-, Tivoli Mine, 
Ipswich (&. Sweet — Colin. Sweet, Melbourne). 
In addition to these localities, the Macleay Museum contains specimens collected 
by the late Eev. J. E. T. Woods, and not mentioned in his Paper, from — Aberdare 
Mine, Ipswich; Eosewood Scrub, near Ipswich; and Pine Mountain, Moreton 
District.

Ohs. Proposed as a variety for that form of T. odontopteroides in which the 
habit was stouter, and probably not so large in growth. The rachis is always grooved 
and more slender, and in some specimens the terminal pinnules form a long lanceolate 
pair. 
The ferns from Petrie’s Quarry, in my Colleague’s Collection, and identified by 
Mr. E. Kidston as this variety, to some extent resemble it, but the pinnules are hardly 
decurrent or falcate enough. Mr. Woods, however, says that they become long and 
falcate as they ascend the rachis, and this is so far borne out by our specimens, in that 
the upper pinnules are much longer and lanceolate than the lower, the latter retaining 
more of their normal wedge-deltoid outline. 
Closely allied to this variety, in all probability, is that denominated var. lancifolia 
by Morris,* and which would appear to have been reflgured by Eeistmantel f without 
remark, from another specimen. Now the plants from Petrie’s Quar’ry have the 
upper pinnules shaped like those of var. lancifolia, but with the lower ones as above 
described, and taking upon themselves the more exact outline of T. odontopteroides. 
One or two are even slightly falcate.
