In the Report of the Geological Survey of Canada, for 1870-71, by 
Messrs. Bailey and Matthew, reference is made to the finding of certain 
sediments which occur in portions of the area surrounding Passama- 
quoddy bay, in the southern part of Charlotte county in New Bruns- 
wick. In these sediments fossils were observed some forty years ago 
which were examined and determined by Mr. E. Billings, the then 
paleontologist of the Geological Survey; but while in many cases much 
difficulty was experienced in determining these forms, owing to the 
great amount of metamorphism which these rocks have undergone, 
sufficient material was obtained from several points, to show, approxi- 
mately at least, their general horizon. Further collections were made 
some years later, which were examined by Dr. J. F. Whiteaves 
in 1883, more especially those from the peninsula of Latete at 
Back bay and points in the vicinity, while still later, in 1903, 
further collections were made from several places by myself and my 
assistants. These have been examined and determined as closely as 
possible by Dr. Percy E. Raymond, the present invertebrate palæon- 
tologist of the Department. 
It must be admitted that owing to the great metamorphism to 
which these sediments have been subjected, either by pressure of the 
associated strata or by direct intrusions of volcanic matter, and the 
consequent distortions which have resulted therefrom, it has been 
very difficult in many cases to decide precisely as to the exact horizons 
of a number of the species obtained. In many cases, therefore, it has 
been practically impossible to determine precisely the several horizons 
represented. Sufficient, however, has been learned from these collec- 
tions to determine the general facies of a number of these organisms, 
and a few notes as to the results of these several examinations will serve 
to place on record our knowledge as now ascertained, and to point out 
certain other features which may later be examined by those interested 
in this subject, and which hitherto have not been clearly elucidated. 
A peculiarity of many of the metamorphic rocks in this area appears 
to lie in the fact that in their present aspect they show many of the 
features, frequently observed in certain Pre-Cambrian rocks, found
