LOWER CAMBRIAN TERRANE 303 



lus zone and its exact stratigraphic relations to the Paradoxides 

 zone. 



Mr. Matthew took up both the above-stated problems and per- 

 sonally examined the sections and collected fossils. His con- 

 clusions differed so radically from what appeared to me to be 

 the correct interpretation of the record as found elsewhere that 

 I decided to study the problems in the field, and prove or dis- 

 prove them. The result, while not all that I could wish for in 

 fossils from the Lower Cambrian of New Brunswick, I think 

 establishes the Lower Cambrian (or Olenellus zone) in the At- 

 lantic Coast Province as distinct, stratigraphically, from the 

 Middle Cambrian (or Paradoxides zone), as outlined by me in 

 1889.^ The Lower Cambrian formations of the Peninsula of 

 Avalon were then referred to the ' Terra Nova' terrane. 



In the correlation bulletin of 1891 the following (p. 304) 

 classification of the formations of the Upper, Middle and Lower 

 Cambrian was adopted.^ 



The basal series of Matthew on Hanford Brook was referred 

 to the Lower Cambrian under the name Hanford. In the text ^ 

 reference is made to the red and green beds of the northwest 

 side of Trinity Bay, as follows : 



Beneath the conglomerate beds of Manuels Brook and be- 

 tween them and the subjacent Archean gneiss, there is, accord- 

 ing to Messrs. Murray and Howley, a series of red and green 

 sandstones, conglomerates, and massive sandstone strata, which, 

 according to their tabulated section, have a thickness of 1800 

 feet. They are exposed on the north side of Trinity Bay and 

 partially on St. Marys Bay. I think we should have more data 

 before deciding that this series of 1800 feet is really subjacent 

 to the Manuels Brook conglomerate ; although it is extremely 

 probable that such is the case, judging from the character of the 

 Trinity Bay and Conception Bay sections. 



Mr. Matthew has shown very clearly that the Smith Sound- 

 Trinity Bay pre-Paradoxides strata are the stratigraphic equiva- 

 lent of the basal series beneath the St. John quartzite in the
