segments ; but the only specimen is too imperfect to justify giving it 

 a specific name. The same may be said of a small but well-marked 

 frament of Pecoptens, consisting of portions of two pinnae allied to 

 P. australis, Morris, but certainly different, as well as of a Cyclo- 

 joteris in Keene's collections in the Geological Society's Museum. 



In Mr. Daintree's upper horizon we find the following plants : — 



T^NioPTEEis Dai]s-te:eei, M'Coy. Plate XXVII. fig. 6. 



Frond simple (?), broad, linear ; midrib somewhat thick; veins 

 leaving it at an acute angle, then passing out at right angles to the 

 margin, once or twice dichotomously divided. 



Loc. Tivoli Coal-mine. 



Cyclopteeis ctjneata, sp. nov. PI. XXVII. fig. 5. 



Form of the entire frond unknown ; pinnae entire, large, cuneate, 

 narrowed at the base, with the distal margins rounded ; veins 

 delicate, once or twice dichotomously divided ; sometimes anasto- 

 mosing once in their length near the middle of the pinna. 



Notwithstanding the slight anastomosis of the veins, these separate 

 pinnae, which are not very frequent, represent a very distinct species 

 of the genus Cydopteris. 



Loc. Tivoli Coal-mine. 



Sphenoptekis elongata, sp. nov. PI. XXVII. fig. 1. 



Frond dichotomously divided, each division irregularly pinnate ; 

 pinnae simple, bifurcate, or irregularly pinnate ; segments narrow, 

 linear, slightly tapering upwards to the somewhat blunt apex ; the 

 single midrib sending out simple branches, which run along the 

 middle of each segment. 



With Pecopteris odontopteroides, Morris, this is one of the most 

 abundant forms. Some specimens have small oval markings scat- 

 tered irregularly on either side of the midrib. These probably 

 indicate the form and position of the sori, which are the same as in 

 some of the simple linear species of Poh/podium. 



Loc. Tivoli Coal-mine. 



Pecopteris odoktopteroides, Morris, in Strzelecki's ' New South 

 Wales,' p. 249, pi. vi. figs. 2-4. PI. XXVII. figs. 2 and 3. 



Frond, with a very short and thick stipes, dichotomously divided, 

 the simple portion at the base of the frond as well as each branch 

 pinnatifid ; the segments more or less opposite, quadrate-ovate, with 

 the apex obliquely truncate, connate at the base ; one vein passing 

 into the centre of the segment and repeatedly dichotomous, several 

 lateral veins, simple or dichotomous, passing direct from the rachis 

 into the upper and under portions of the segment. 



In the form of the segment our plant diff'ers considerably from 

 the specimens figured and described by Prof. Morris. It nevertheless 

 belongs, I believe, to the same species. I am able to describe and
