Feet 



(3) Greenish argillaceous shale, conformably subjacent to 2 40 



(4) Reddish-colored argillaceous shale 4 



(5) Calcareous sandstone, with pinkish limestone in irregular masses 2 



(6) Green argillaceous shale with thin layers of hard, dark, ferruginous sand- 



stone, interbedded at several horizons 270 



Strike N. 80° E. ; dip 12° N. 



Fossils : Near the base the head of an Olenellus was found ; also frag- 

 ments of an Agraulos or Ptychoparia. At 218 feet from the base a 

 layer of pinkish limestone contained the head of an Agraulos, like A. 

 strenuus, and many fragments of trilobites. Fifty-two feet higher up 

 quite an abundant fauna was found, and the following species were 

 collected : Lingulella sp. a., Acrothele malthewi, Agnostus sp. a., Agnostus 

 sp. d., Paradoxides hicksi, Conocoryphe matthewi, and Liostracus sp. a. 



(7) Dark argillaceous shales with thin layers of limestone and sandstone at 



various horizons 295 



Fossils : Zone A: From 10 to 20 feet from the base the following spe- 

 cies were collected : Lingulella sp. a, Linnarssonia misera, Acrothele 

 matthewi, Hyolithes sp. a, Agnostus 3 sp. a, b, c, Microdiscus punctatus, 

 Paradoxides hicksi, Conocoryphe (C.) matthewi, C. elegans, Agraulos socialis, 

 and Liostracus tener. 



Zone B : Forty-five feet higher the fauna is much larger and includes : 

 Linnarssonia misera, Lingulella sp. a, Orthis sp.?, Slenotheca sip . ', Agnos- 

 tus punctuosus, Agnostus 5 sp. b, e, f, g, h, Microdiscus punctatus, Paradox- 

 ides davidis, P.hicksi, Paradoxides, sp., Anopolenus venustus, Conocoryphe 

 elegans, Ctenocephalus matthewi, Erinnys renulosa, Ptychoparia robbi, P. 

 variolaris, Holocephalina injlata and Agraulos socialis. 



From 235 to 250 feet from the base a belt occurs in which a small 

 species of Aristozoa occurs in large numbers, associated with Lingulella 

 sp.o, Agnostus sp. f, and the heads of a small Ptychoparia? sp. undet. 



(8) Alternating bands of dark shale and dark, compact sandstone that carry 



a small species of Orthis in large numbers 400 



The section is here cut off by the shore of Conception Bay. 



The fauna of No. 2 is essentially the same as that of the limestones 

 of the Topsail Head and Brigus sections, and proved conclusively that 

 the Olenellus fauna is subjacent to the Paradoxides fauna. 



Beneath the conglomerate beds of Manuel's Brook and between them 

 and the subjacent Archean gneiss, there is, according to Messrs. Mur- 

 ray and Howley, a series of red and green sandstones, conglomerates 

 an<i massive sandstone strata, which, according to their tabulated sec- 

 tion, have a thickness of 1,800 feet. They are exposed on the north 

 side of Trinity Bay and partially on St. Mary's Bay. I think we should 

 have more data before deciding that this series of 1,800 feet is really 

 subjacent to the Manuel's Brook conglomerate; although it is extremely 

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

 ity Bay and Conception Bay sections. 



On the islands in the bay the Upper Cambrian horizon is well devel- 

 oped. In the lower arenaceous shales at Lance Cove, on Great Bell Isl- 

 and, were found JEophyton sp. f , Cruziana semiplicata, Arthraria anti- 

 quuta, Olenus sp. undet., and at a higher horizon, near the center of the 

 island, Lingulepis affinis and Lingula f murrayi, with fragments of Cru-
