Sphenopteris germane, M'Coy, loc. cit. p. 150, Bi-pinnate, 

 pinnae oblique, alternate, elongate, ovate, with a narrow membran- 

 aceous margin, pinnules oval, deeply pinnatifid, lobes very oblique, 

 elliptical, generally three on each side, and the apex of the 

 pinnules 3-lobed, veins bi-pinnate, three branches reaching the 

 margin of each lobe. Obs. — It is extremely difficult (says Prof. 

 M'Coy) to distinguish this species from the Pecopteris murrayana 

 of the Yorkshire Oolitic coalfields, with which it is nearly identical 

 in form and neuration. The oval outline of the pinnules is the 

 most obvious character, contrasting with the trigonal wide-based 

 leaflets of the English plant. This, together with their more 

 oblique setting on the rachis, more oblique, narrow, and deeply- 

 cleft lobes, and the decurrent, narrow, alate margin to the straight 

 rachis, will, I think, be sufficient to distinguish the species in the 

 shale of Mulubimba. 



Sphenopteris plumosa, M'Coy, loc. cit. Bi-pinnate, pinnae curved, 

 elongate, narrow, plumose, margin slightly alate to the 

 rachis, pinnules close, oblique, ovate pointed, deeply cleft into 

 about four oblique mucronate lobes on each side, exclusive of the 

 largely trilobed apex, veins strong, much branched, so that about 

 six branches reach the margin of each of the lobes of the lower 

 side, and seven to each of those of the upper margin. Obs. The 

 number of the lobes of the pinnules and complexity of the neura- 

 tion will readily distinguish this species. The average length of 

 the leaflets, five lines. Rare in the shale of Mulubimba. 



Sphenopteris Jlexuosa, M'Coy, loc. cit. Bi-pinnate, pinnae long, 

 with a strong flexuous naked rachis. Pinnules large, moderately 

 oblique, unequal, ovate, sides cut into two very large unequal 

 rounded lobes on each side. Apex tri-lobed. Veins strong, much 

 branched, seven branches reaching the margin of each lobe, and 

 three going into each of the three lobes of the apex. Obs. This 

 strongly-marked species is not sufficiently allied to any known form 

 to render a comparison necessary. The average length of the 

 pinnules is about eight lines, width four lines. In a bed of brown 

 clay, Mulubimba.
