152 NOTES ON THE GEOLOGY OF NEWFOUNDLAND—WESTON. 
refers to other forms found in Huronian argillite by the 
Rev. Mr. Harvey. At the time of the discovery of these fossil- 
like markings they were considered to be most important, and 
were supposed to belong to the genus Oldhamia, and specimens 
were sent to Sir W. E. Logan. Billings would not decide one 
way or the other as to their organic affinity, and they were 
handed to me. I said at once they were concretionary, and, what 
had not been observed by others, that these markings lay trans- 
verse to the bedding of the slate in which they were.* 
Billings describes his Aspidellu terranovica thus: “Small 
ovate fossils five or six lines in length, and about one-fourth less 
in width. They have a narrow ring-like border within which 
there is a concave space all round. In the middle there is a 
longitudinal roof-like ridge, from which radiates a number of 
grooves to the border. The general aspect is that of a small 
Chiton or Patella, flattened by pressure. It is not probable, 
however, they are allied to either of these genera.” 
While in the City of St. Johns in 1874, I made a diligent 
search for these forms and collected several of the so-called Aspi- 
della. These, together with all other specimens now in the 
Dominion Geological museum, vary so much in form and appear- 
ance that I am afraid they also will ultimately be classed with 
the concretionary forms already spoken of, collected by the Rev. 
Mr. Harvey. Thus it will be seen that we have no definite 
organic remains either in the Laurentian or Huronian rocks of 
Canada or Newfoundlana.

—In spite of the oft-repeated assertion of Professor Jukes and 
the late director of the Geological Survey of Canada,—* If the 
fossils don’t agree with the stratigraphy, so much the worse for 
the fossils,’ my long experience as a collector of fossils and 
close observer of the various geologic horizons leads me to think 
that if the stratigraphy does not agree with the fossils so much 
the worse for the stratigraphy. To illustrate the faith the late
