Locality and Horizon. — Associated with the former in a light-coloured 
shale from the Hawkesbury River, New South Wales (prohahly Newcastle 
Beds).* 
Spiienopteris Baileyana, Ten. Woods. 
Spiienopteris Bailey ana, Tenison Woods, 1883, Joe. cit., p. 93, PI. 4, f. 2. 
iSp . Char. — “ Frond hipinnatifid, membranaceous, rachis winged ; pin- 
nules alternate, almost simple, broad at the base, becoming regularly narrower 
at each lobe, so as to form an almost conical leaflet, emerging at an open angle 
and curving upwards, the lower shorter, the upper longer and spreading; 
lobes linear, narrow, rounded, very slightly segmented, much longer in the 
upper pinnules, the terminal lobe produced; costa conspicuous, reaching the 
apex ; veins very fine, emerging at an acute angle, bifurcating immediately, 
sending a venule to the end of each lobe.” 
Locality and Horizon. — In the Carbonaceous beds at Rosewood, near 
Ipswich (Mesozoic, Jurassic ?). 
Spiienopteris crebea, Ten. Woods. 
Sphenopteris crelra, Tenison Woods, Joe. cit., 1883, p. 93, Pi. 3, f. 4. 
Sj). Char. — “Frond evidently tender and membranaceous, bipinnate ; 
pinnae wide, alternate, slightly oblique, oblong, quadrate ; pinnules so close 
together as not to be easily distinguished, faintly pinnatifid ; lobes a little 
more oblique than the pinnae, oblong ovate, with a slightly undulating 
margin ; costa sending off veins, which fork once, and the venules reaching 
the margin.”

South Wales (Hawkesbury beds, ? Trias.) t

* [As in the ease of tlio former species, this probably came from the Ilawkesbury Series. The Newcastle 
Coal Measures do not occur on the Hawkesbury River proper. — R. E., jun.] 
t [Mr. C. S. Wilkinson states that “ Jn lithological character the Baltimore beds somewhat resemble the 
Upper Coal Measures of Newcastle', to which they may belong.” (Notes on the Geology N. S. Wales, 2nd 
edit., 1887, p. 72 ) The Rev. J. Milne Curran regards these beds as older than either the Hawkesbury or Clarence 
Scries. — R. E., jnr.]
