LOWER CAMBRIAN TERRANE 307 



Cambrian, and corresponds in stratigraphic position to 

 the St. John quartzite of the New Brunswick Cambrian. 

 One observes no difference, in either strike or dip, between 

 the shales beneath this band of nodular limestone and 

 conglomerate and the shales above it until one passes to 

 the east of the faidt-line that cuts through and breaks 

 the band a few feet above the water's edge. 



Lower Cambrian (Etcheminian of Matthew). — 



Feet. 

 2a. Reddish-purple argillaceous shale with'greenish shales in 

 bands at irregular intervals and a massive band of 



greenish shale near the base 284 



Dip near base 20° to 23° W. 



At no feet from the summit fragments of a'large undeter- 

 mined trilobite were noted. On the south side'of Smith 

 Sound, at Britannia Cove, Olenellus (H.) broggeri oz- 

 curs at a horizon corresponding to 140 feet below the 

 summit of the stratum. 



Near the base of 2a the following fossils were found : 

 Obolella atlantica 

 Hyolithes sp. 

 Orthotheca sp. 

 Microdiscus sp. undet. 

 Olenellus (^Holmia~) broggeri 



Solenopleiira? bombifrons? 



Inches. 

 2b. Greenish-colored arenaceous limestone, passing into an 

 intraformational conglomerate formed of nodules of 

 pinkish limestone mixed with fine sand and carrying 



numbers of fragments of trilobites 16 



Pinkish-colored nodular limestones 8 



Fossils : Fragments of trilobites and a small brachiopod. 



Feet. 



20. Reddish-purple to brick-red argillaceous shale 56 



The following fossils occur in the central and lower por- 

 tions of this band : 

 Obolella atlantica 



Microdiscus bellimarginatus S. & F. 

 Microdiscus n. sp. 

 Olenellus ( Uolmia) broggeri 

 Zacant/ioides sp. undet. 

 Agr aulas sp.
