FROM LOWER PALÆOZOIC ROCKS. 169 
These are all well-known Point Levis species, according to the classical monograph of 
Prof. Hall, and they also occur together upon the corresponding Arenig-Skiddaw horizon 
in Europe, in the Shelve Arenigs, in the Skiddaw Slates, and in the Phyllograptus beds 
of Norway and Sweden. 
If, as I believe, there are several zones in the Point Levis beds, this zone is probably 
about the middle of the series as there represented. Some of the Point Levis forms figured 
by Hall are apparently older and a few newer; that is to say, if we may rely upon the 
European evidences at our command. 
It is somewhat remarkable that there is no other trace whatever of this Ste. Anne 
Phyllograptus zone in the present collection, among the fossils from the east of River Ste. - 
Anne. The lithological characters of these Phyllograptus-bearing strata are, according 
to my experience of Graptolitic rocks, those of a zone likely to be persistent for great 
distances. 
It would be interesting to know whether the form of this zone are met with 
associated with the Phyllograptus said to occur in the shales among the sandy rocks near 
Cape Chatte (Geol. Rep., 1880-1-2, p. 26 pp.) On one point we may, I think, assure 
ourselves, with our present knowledge of the Graptolites of Europe, viz., that the 
Phyllograptus beds of Ste. Anne are newer than the Bryograptus beds of Cape Rosier, 
and older than all the other zones in this collection. This zone answers precisely to the 
typical Arenig (Phyllograptus) beds of Wales, Skiddaw, Norway and Sweden, as well as 
to the typical zones of Phyllograptus, ete., at Point Levis. 
This Phyllograptic zone ought to be sought for among the green and purple rocks 
between Cape Rosier and Griffin Cove, and among the sandy and conglomeratic rocks 
along the coast where the Pillar Sandstones come out in force far to the east of the 
Ste. Anne. The Dictyonema bed again should be sought for at Point Levis and elsewhere, 
and its relation to the so-called “limestone conglomerates” demonstrated. The line 
between the Cambrian and Ordovician (Cambro-Silurian) must, in time, be drawn very 
near this zone of Dictyonema and Bryograptus. 
Zone IIL—Grifin Point or Marsouin River Zone: Zone of CŒNOGRAPTUS GRACILIS. 
This zone is by far the most fully represented in the collection. The chief localities 
which have yielded its fossils are:—Marsouin River (a little above), one mile east of 
Griffin Cove, one mile above Tartigo River, north-west point of Griffin Cove, half a mile 
below Little Méchin River, near Fox River; one mile above Cap Rouge, near Quebec, and 
the Little Falls, Magdalene River. 
In all these localities the fossils are essentially the same, the same species recurring 
again and again, in some cases in about the same relative proportion. It will be seen from 
the table, that the list of fossils is more complete from some localities than from others. 
It may be that it will be possible, in time, to subdivide this zone, which has probably 
quite as great a vertical extent in Canada as it appears to have in England, but as yet it 
is decidedly safest to refer all the rocks named above to this single zone,
