[MATTHEW] ON SOME NEW SPECIES OF DEVONIAN PLANTS 187 
Size.—Diameter of the thallus about 40 mm.; some branches or 
lobes extend 25 mm. Ê 
Horizon and Locality.—Lower Cordaite Shales, Lancaster, N.B. 
Exact plant bed unknown, but probably No. 2 or No. 3 of C. F. Hartt’s 
section. 
The plant occurs in association with sprays of fern leaves and 
stems of Calamites, though apparently not growing within the tissues 
of any of them. 
By comparison with the plants that occur with it, it will be seen that 
this species must have been composed of a dense aggregation of cells, for 
it gives a brighter reflection from the surface of its graphitized thallus, 
than emanates from the stout veins of an Aphebian Cyclopteris that 
lies adjacent on the shale. It appears to have been much thicker or 
of denser texture than a fossil from the Coal Measures of Pennsylvania, 
which Lesquereux has referred to this genus, and which branched in 
a similar manner.* 
2.—Plants from the Upper Devonian of Nova Scotia and 
New Brunswick. 
During last summer members of the staff of the Geological Survey 
of Canada, under the direction of Dr. R. W. Ells, were engaged in 
exploration near St. John, and met with some plant remains in the 
lower part of the Kennebecasis valley which were sent to me for study. 
They consisted chiefly of various species of Lepidodendron, several of 
which were Devonian types. The terrane in which these plants occur 
had been traced by the writer and other geologists many years ago to 
a connection with the Albert shale deposits, which the late Sir Wm. 
Dawson asserted to be of Lower Carboniferous age, and equivalent to 
the Shales of the Gaspereau R. and Horton Bluff in Nova Scotia, desig- 
nated by him “ Lower Coal Measures.” 
There had been in the Museum of the Natural History Society of 
New Brunswick for many years, and in my own cabinet, quite a con- 
siderable collection of the plant remains of the Gaspereau R., of this 
formation which had been collected by the late Professor C. F. Hartt 
at the time that he collected the material from which Sir William 
described his species from this locality. It occurred to the author that 
an examination of this material might throw some light on the vexed 
question of the geological age of this terrane, so widely spread in 
southern New Brunswick and northern Nova Scotia, the result of this 
investigation is shown in the following pages, and from the facts pre-
