254 THE DEVONIAN FOSSILS OF CANADA WEST. 
Locality and formation—Township of Bosanquet, lot 25, con. 5. 
Shales of the Hamilton Group. 
Oollectors.—A. Murray, J. Richardson. 
STRIATOPORA FORMOSA.—N. Sp. 
Description.—Stems from one line and a half to three lines in 
thickness ; cells of an uniform size or very nearly so, three-fourths 
of a line in width, opening out on the surface at an angle of about 
45° with the longitudinal axis of the stem, the cell mouths very gra- 
dually expanded, apparently fifteen fine obscure strive occupying the 
whole surface of the upper lip. 
This species differs from S. Linneana in having the cells smaller 
and of an uniform size. The cell mouths are as wide in stems, one 
and a half lines in thickness, as they are in the largest specimens 
seen. I have not ascertained the angle at which the stems bifurcate. 
In perfect specimens, where the cells are empty, on looking into them 
obliquely downwards, they are seen to become circular just below the 
edge of the lower lip, their diameter there being a little less than half 
the transverse width of the mouth. 
Locality and formation.—Corniferous Limestone, near Woodstock. 
Collector.—A. Murray. 
Genus TRacuyrora-—(Edwards and Haime.) 
Generic characters.—‘‘ Corallum dendroid, the branches presenting 
calyces which are only slightly salient, and in which there are no ra- 
diating septa; coenenchyme very abundant, solid, and with the surface 
marked by strong, irregular, vermicular, and sub-echinulated striz.”’

zoiques. Page 305.) | 
The only species of this genus heretofore known, is 7’. Davidsoni 
(E. and H.), which occurs in the Devonian Rocks at Ferques, in 
France. 
TRACHYPORA ELEGANTULA.—W. Sp. 
(See Figs. 2, 3, 4.) 
Description.—Stems (in the specimens examined) from two to two 
and a half lines in diameter, branching at an angle of about 75°. 
Cells arranged in four or five rows, parallel with the axis of the stem ; 
they are oval, about one line in length and two-thirds of a line wide, 
with an elevated margin at the sides, in general effuse above, rarely
