BAILY ON FOSSIL PLANTS FROM THE SOUTH OF IliELAND. PART I. 43 



procured, before a clue can be obtained towards the elucidation of their 

 history, or even sufficient to explain the relation of the several parts to 

 each other; want of the necessary information, and too hurried an exa- 

 mination having repeatedly led to the mistake of applying distinct 

 names to different parts of the same fossil plant or animal. The remark- 

 able group of Plants to which this species of Sagenaria belongs is cha- 

 racterized by its conspicuous leaf scars, arranged in a spiral manner, and 

 more or less distant from each other; they are very abundant amongst the 

 Plant remains collected at Kiltorcan ; several of the varieties are figured 

 and described by the Eev. Professor Haughton, M. D., F. E. S.*, under 

 the name of Cyclostigma. The large fossil fern Adiantites Jlibernicus, 

 accompanied by the freshwater bivalve shell Anodonta Jukesii, and the 

 stems referred to Sagenaria, has been found at several other places in 

 the neighbourhood. 



The next important fossil Plant locality to be mentioned is that a little 

 east of Tallow Bridge, in the county of Waterford, in a cutting for the new 

 road, through dark grey shales, full of Plant remains, described by the 

 Geological Surveyors as the upper part of the Old Eed Sandstone. At 

 this place stems of large size may be seen crossing each other in all di- 

 rections, some of them five or six feet in length, and six inches in 

 breadth, coarsely ribbed lengthwise, and dividing into smaller branches, 

 which again subdivide; the surfaces of these smaller branches showing 

 a beautiful arrangement of alternating markings, the remains of leaf 

 scars, giving them a lattice-work appearance. It is impossible to bring 

 away these fossil Plants entire, in consequence of the number of joints 

 crossing them. I have visited the place in connexion with my duties 

 on the Geological Survey, and made a drawing of the appearance they 

 presented on the spot, which, with the description of the locality, was 

 inserted in the Explanation to Sheet 187, &c, of the Maps of the Geo- 

 logical Survey. I believe it to be the same description of Plant which 

 occurs at Kiltorcan, and which I have referred to Sagenaria Veltheimi- 

 ana. The Eev. Professor Haughton gives an account of this remarka- 

 bly rich deposit of fossil Plants. f These Plants, although so abundant, 

 belong for the most part to one species only, that already alluded to as 

 Sagenaria Veltheimiana ; and, as at Kiltorcan, a plant like Stigmaria has 

 been observed here, which is most probably the root of Sagenaria ; 

 smaller branching Plants, named by me Filicites lineatus, and masses 

 of a grass-like character, perhaps rootlets, were all the varieties observed 

 at this place. 



Plant remains have been collected by the officers of the Geological 

 Survey at a few other places in the same county. On thePermoy road, 

 one mile west of Tallow Bridge, branching plants occur in grey slate, 

 with a bivalve shell — Modiola Macadami, a marine or brackish water 

 species, characteristic of the Carboniferous slate. At Salter Bridge,
