“Frond dicliotomously divided, each division irregularly pinnate; 
pinnae sini])lc, bifurcate or irregularly pinnate ; segments narrow, linear, 
slightly tapering upwards to the somewhat blunt apex, the costa sending out 
simple veins, which run along the middle of each segment.” 
Ohs. — Carruthcrs says that, besides Thinnfeldia ( Tccopteris ) odon- 
topteroides, it is the commonest fossil, which, however, Mr. Tenison Woods 
could not confirm. 
Locality and Horizon. — In the Upper Carbonaceous beds at the 
Tivoli Coal Mines, Ipswich, Queensland ; in similar beds in the Jerusalem 
Basin, Tasmania ( Crepin ). (Mesozoic, Jurassic.) 
Sphenopteris plabellifolia, Ten. Woods. 
Sphenopteris (Aneimioides) flabcllifolia, Tenison Woods, Joe. cit., 18S3, p. 0-1. 
Sp. Char. — “ Frond delicate, small, bipinnate ; racliis terete, some- 
what thick; pinnae oblong, cuneate, contracted at the base to a delicate 
petiole, lower edge entire, upper divided into linear cuneate lobes of varying 
width, the edges straight or rounded, some of the pinnae much elongated ; 
costa inconspicuous ; veins tine, close, numerous, straight, radiating.” 
Locality and Horizon. — Abundantly found in a blue shale on the

The distinction of this fossil seems hardly to be justified even as a 
variety. 
Locality and Horizon. — At the same locality as the preceding.
