138 ON THE FOSSIL FLORA OF THE COAL DEPOSITS OF AUSTRALIA, 



" On Cyclostigma : a new genus of fossil plants from the old red 

 sandstone of Kiltorkan."* 



Cyclostigma austr ale. Feistmantel, loc. cit. p. 76. A tree trunk 

 with slender terete branches, cushions or raised scars subglobose, 

 pitted, approximate, spirally disposed, impressions oblong oval, 

 rather deep, situate in the upper portion of the oblong ovate 

 tubercle. The species was found in two places in New South 

 Wales, according to Dr. Feistmantel, named Goonoo Goonoo Creek, 

 near Tarn worth, and at Smith's Creek. Dr. Feistmantel was of 

 opinion that the species was so near C. kiltorkense that he could 

 see little difference, but lest he should make a false identification 

 in a plant where the details are so few and simple, he preferred to 

 give it another name. He gives figures of a few specimens at pi. 

 i, fig. 6, a doubtful identification, pi. iv., fig. 3, pi. v, fig, 1, pi. 

 xxii, fig. 1. Amongst the Drummond Range specimens I have 

 only one which can be referred with any probability to this species, 

 and in this case the impressions are so faint and worn that I 

 figuied it as a Stigmaria {pydostigma ?). I quote from the Rev. 

 Dr. Haughton's paper somewhat fully, because his description 

 corresponds so well with the strata of the Drummond Range that 

 lithologically they may certainly be said to belong to one forma- 

 tion. The rose pink sandstone in which some of the fossils are 

 embedded, and the golden yellow colour of others, is especially 

 remarkable. 



11 The fossil plants of the yellow sandstone of the county 

 Kilkenny occur, as they do in other parts of Ireland, in the 

 sandstone lying immediately under the great mass of the Car- 

 boniferous limestone, which constitutes the most important member 

 of our Irish fossiliferous rocks. They are found at Jerpoint, 

 about a mile and a half south of the Abbey, on the roadside near 

 the cornmill, on the road to Bally hale, about 90 feet below the
