and Rouveroy, Belj^ium, as L. gaspianum Dn. Dawson says " The 

 Lepidodondron from the Devonian of Beljrium, described and figured 

 by Crepin .... would seem to prove that this species existed in 

 Europe as well as in America (Canadian Nat., vol vii, 1878, p. 

 380); while Kidston, in commenting on these figures, says "it 

 is evident that pis. iii, iv, and v of Lepidodevdron Gaspianum 

 Crepin (? not Dawson) are the Psilophyton Dechenianits Goppert, 

 sp. As to those specimens which he figures on pis. i and ii I can- 

 not express an opinion, as I have not seen any similar Lepidoden- 

 dron-]\ke fossils .... The entire agreement of Cr^pin's pis. iii, 

 iv, and v with the figures given by Hugh Miller and Mr. Carruthers 

 proves conclusively that all these specimens belong to one species — 

 the Fsilopfn/fon JDe.chenianin^ Goppert, sp , as interpreted bv Mr. 

 Carruthers (Cat. Palaeozoic Plants, 1886, p. 234). ' . 



Zeiller, Bull. Soc. Geol. de France, 3d ser., vol. viii, 1880, p. 504, 

 mentions a specimen from the Devonian of Caffiers, France, which 

 is compared with L. gaspiaiium. 



J. C. White, 2d Geol. Snrv. Penna., q\ 1881, pp. 65, 78, 79, re- 

 ported specimens from the Shenango group, sub-Carboniferous, near 

 Jamestown, Crawford County, Penna., which he considered as 

 " Lepidodendron Gaspianum, or a closely allied plant ;" also, from 

 the same formation near Townville, Crawford County (op. cit., p. 

 191). Professor White compares these specimens with the one 

 figured by H. D. Rogers (Geol. Penna., vol. ii, 1858, pi. xxi, fig. 2, 

 and mentioned on p. 830) from the Vespertine sandstone (Pocono) 

 at Mauch Chunk, Penna., which does not seem to agree closely with 

 L. gaspianum Dn. 



Lesquereux, 2d Geol. Surv. Penna., P, vol. iii, 1884, p. 852, re- 

 ported the species from the Waverly sandstone (sub-Carboniferous) 

 of Rushville, Ohio, but without any confirmatory evidence. 



Dr. J. M. Clarke, Bull. U. S. Geol. Surv., No." 16, 1885, pp. 26, 

 33, reported the identification of this species b}^ Dr. Dawson from 

 the Styliola layer of the Genesee shale of Ontario County, New 

 York; and from the Naples beds (Portage) of Naples, Ontario 

 County (op. cit., p. 64). Also, see Rept. State Geologist [New 

 York] for 1884, 1885, pp. 18, 19, 21, where the same occurrence of 

 the species is mentioned bv Dr. Clarke. 



White, 2d Geol. Surv. "Penna., T^ 1885, p. 299, reported the 

 species from the Pocono along Shoup's run railroad. Carbon town- 

 ship, Huntingdon County, Penna. 



Lesquereux, Proc. U. S. Nat. Mus., vol. ix, 1887, p. 28, identified 

 two specimens from the Pocono of Lewis Tunnel as belonging to 

 this species. Only one of these specimens has been seen ; but that 

 appears to belong to a species quite different from L. gaspianum Dn. 



Finally, the range and distribution of this species may be given 

 concisely as follows : i)robably from the Corniferous limestone of 

 Ohio ; Middle Devonian of Gasp^ and New Brunswick ; Hamilton, 

 Genesee, Portage, and Chemung (?) of New York; Chemung (?) 

 of Pennsylvania ; Upper Devonian of Maine and Gasjid : Pocono
