quarries, 1 was guided by Mr. Seott, the manager of the Clifton quarry, 

 to a spot where a fall of rock had recently taken place and had thrown 

 down a great slab of argillaceous sandstone or coarse shale, on which 

 was laid out, as if pre^Dared for an herbariilm, the specimen represented 

 in Fig. D. 



As the mass of rock was too large to be removed entire, I made a 

 rough sketch of the whole plant in my note-book, and cut out specimens 

 as large as 1 could take away, showing the trunk, branches and cones. 

 Other matters, however, were at the time occupying my attention, and 

 the specimens were not described till 1888, when a short description was 

 given in my '• Creological History of Plants," at which time I regarded 

 the plant as a Lepldodeadron. nearly allied to L. Wortheni of Lesquereux. 

 Two years later, a collection of plants from the coal formation of New- 

 foundland was placed in my hands by the late Mr. Murray, F.G.S., 

 Director of the Geological Survey of ISTewfoundland, and his successor, 

 Mr. Howley, F.Gi-.S. Among these was a remarkable Lepidodendron, which 

 I named L. Murrayanum, and which raised a number of questions as to 

 the group to which L. Wortheni belongs, and some members of which 

 had been described as Sigillaria', because of the apparently vertical 

 arrangement of the leaf- bases. The Newfoundland collection was de- 

 scribed in the Bulletin of the Greological Society of America for 1891. and 

 led to the re-examination of the Clifton specimen in the manner shown 

 in the following extract : 



III. The Relation of these Species to Others. 



" In the coal formation of New Brunswick there is a species which I 

 have described as L. Cliftonense from its locality,' and of which I have 

 found very ]3erfect specimens. It is in some respects so near to the above 

 that I have doubted its specific distinctness, though on careful com- 

 parison there seem sufficient grounds for a difference of name. I there- 

 fore figure this species also, more especially as it has not been before 

 figured and as it shows the fruit and habit of growth. 



" It will be observed that this species agrees with the last in the forms 

 of the leaf-bases and in the length of the leaves, which are, however, 

 wider and sometimes as much as five inches in length, while the leaf- 

 bases are transversely furrowed above as well as below the scars. The 

 leaf-bases also are somewhat diflerent in shape and more spirally ar- 

 ranged, and the leaves are longer in L. Cliftonense. Additional speci- 

 mens might, however, show them to be varieties of one species. The 

 foliage reminds one at first sight of that of i. longifolium of Sternberg, 

 but both leaves and scars are altogether difierent in detail.
