Lepidodendkon forulatum, Sp. 110V. 
tv 
PI. xxiil, fig. 5 to 8. 
Cicatrices distant, oval, narrower and pointed at both ends, 
wrinkled across; leaf scar large, central, marked with three 
distinct large vascular points, without medial line or appenda¬ 
ges; corticated surface deeply undulate-wrinkled lengthwise, 
marked by deep, narrow, equally distant furrows, separating the 
cicatrices in vertical rows as in the genus Sigillaria. The de¬ 
corticated surface, fig. 7 and 8, is regularly striate lengthwise 
by narrow, nearly straight wrinkles, and has its cicatrices up¬ 
raised or convex-rhomboidal, split from the central point down¬ 
wards, by a deep narrow line. 
The peculiar furrowing of the surface of this species does not appear merely 
casual. A disposition of this kind has already been observed, though not quite 
as distinctly marked, in Lepidodendron costatum, Lesqx., described and figured 
in the second volume of this Report. 
Found at St. Johns, in the roof shales of the main coal. 
Lepidodendron Tijoui. Sp. nov. 
PI. xxiv, fig. 1 to 3. 
Cicatrices of the cortex proportionally .small, ovate, long 
pointed at both ends, separated by a flat irregularly wrinkled 
border, about one line broad; leaf scar large, placed above the 
middle, smooth, marked by its three vascular points, without 
medial line or appendages; cicatrices of the decorticated sur¬ 
face of the same form, smooth, merely marked in the middle 
by a vertical line, fig. 3, (35 enlarged). A small piece, fig. 2, 
of the same, though taken from the largest part of the tree, 
preserves the form and distance of the cicatrices as in the spe¬ 
cimen of fig. 1. The coat of coaly matter covering the surface 
is thin, smooth, and the place of the leaf scars is hardly indi¬ 
cated on it.
