 Cape Breton and New Brunswick— Continued. 



a Fossils from the Lower Cambrian have been identified at but two localities (3a and 301 v), and these are on Hanford Brook, near St. John, New 

 Brunswick. The Lower Cambrian is not represented in the brachiopod collections from Cape Breton. 



Colorado. 



Most of the Colorado forms occur in the siliceous beds of the Lower Ordovician. Three localities (360g-i) have 

 been identified from the Upper Cambrian and two (3g and 360d) from the Middle Cambrian. For the numbers of all 

 the localities see the index.

See Sweden, Denmark, Finland, and Norway, where the horizons are more or less closely differentiated and corre- 

 lated, with complete lists of localities and included species.
