146 TRANSACTIONS OF THE [JUNE 6, 
and Rouveroy, Belgium, as L. gaspianum Dn. Dawson says “ The 
Lepidodendron from the Devonian of Belgium, described and figured 
by Crépin . . . . 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 pls. iii, iv, and v of Lepidodendron Gaspianum 
Crépin (? not Dawson) are the Pstlophyton Dechenianus Géppert, 
sp. As to those specimens which he figures on pls. i and ii I can- 
not express an opinion, as I have not seen any similar Lepidoden- 
dron-like fossils .... The entire agreement of Crépin’s pls. 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 Psilophyton Dechenianus Géppert, sp., as interpreted by Mr. 
Carruthers (Cat. Paleozoic Plants, 1886, p. 234). 
Zeiller, Bull. Soe. Géol. de France, 3d ser., vol. viii, 1880, p. 504, 
mentions a specimen from the Devonian of Caffiers, France, which 
is compared with ZL. gaspianum. 
J. C. White, 2d Geol. Surv. 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, pl. 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 
LT. 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 by 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 by 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 LZ. gaspianum Dn. 
Finally, the range and distribution of this species may be given 
concisely as follows: probably from the Corniferous limestone of 
Ohio; Middle Devonian of Gaspé and New Brunswick; Hamilton, 
Genesee, Portage, and Chemung (?) of New York; Chemung (?) 
of Pennsylvania; Upper Devonian of Maine and Gaspé; Pocono
