THINNFELBIA. 95 



Genus THINNTBLDIA, Ettingshausen. 

 [Abh. k.-k. geol. Eeichs. vol. i. Abth. 3, p. -2, 1852.] 



Some at least of tte imperfect speoiDjens described below are 

 referred ■with.out hesitation to the genua Thinnfeldia, as represented 

 "by T. speciosa, Ett. ; others exhibit a- close agreement with species 

 included by Saporta in his genus Stempteris. The Stonesfield 

 material is very meagre and imperfectly preserved, but on the 

 whole I believe it is better to refer all the specimens to Thinnfeldia, 

 limiting the generic name Stenopteris to plants with narrow linear 

 ultimate branches in which no lateral veins occur. An example of 

 Stenopteris, using the term in this sense, is afforded by a species 

 •described by Carruthers from Khaetic beds in the Argentine as 

 Sphenopteris elongata^ and recorded also from the Stormberg beds 

 ■of Cape Colony.^
