[ELLS] FOSSILS FOUND IN SOUTHERN NEW BRUNSWICK 23 
masses of the green diabase are integral parts of the formation while 
traces of the squeezed corals are also to be observed in the crystalline 
limestone. While it has not yet been possible to connect directly the 
Latete and L’Etang areas with those of the Mascarene shore the resem- 
blance of the sediments in the several places is such as to warrant the 
inference that their horizons are very closely related. 
Thus in the traverse of the shores and areas along Clark head on 
the Mascarene shore the presence of fossils was recognized at several 
places, the strata consisting of red, green, purple and variegated shales 
with rhyolitic tuffs and diabase flows. From the rocks of this area, 
collections of organisms were later made by the members of the party 
from the U. 8. Geological Survey which had been working in the East- 
port Silurian areas. In these Clark head collections were a number of 
forms clearly identifying these rocks with the Eastport Silurian, while 
a lingula (L. cornea of Sowerby), was abundant, and on examination 
proved to be the same as the characteristic fossil of the English Teme- 
side, which apparently represents the upper part of the upper Silurian 
(Ludlow division) of the English series.* 
From the evidence of all the material as yet obtained from various 
places along this part of the Bay of Fundy coast it is highly probable 
that the rocks in this part of the province which have been assigned 
to various portions of the geological scale may properly be regarded 
as upper Silurian, the mistakes which have arisen in their interpretation 
in earlier times being due to the changes in the various sediments 
caused by the metamorphism induced by the large amount of igneous 
intrusions which have affected this district. 
In connection with the work recently carried on along the shores 
of Passamaquoddy bay and in a number of islands including Campo- 
bello and Deer islands, some facts of considerable interest have been 
brought to light. These rocks were for some years regarded as of 
probably Pre-Cambrian age and a part of the Kingston series. In the 
course of our study of this district, four years ago, traces of organisms 
were observed at a number of points, but these areas were so intimately 
associated with felsitic and diabase rocks and most of the organisms 
appeared to be so much altered as to be largely almost undecipherable. 
When contrasted with the fossiliferous series seen in the vicinity of East- 
port on the adjacent coast of Maine, a marked similarity both in the 
nature of the rocks themselves and in that of the contained fossils was 
perceived, sufficient to warrant the statement that the Eastport rocks 
were practically of the same horizon as those of the two islands just
