Instituting comparisons between the sections of Sweden and New 

 Brunswick, he discusses the general relations of the Cambrian fauna 

 of North America. The organic remains found in band B are an 

 Agraulos, and at the base of the zone an Ellipsocephalus, of the type 

 associated with Olenellus (?) Jcjerulfi in Europe. At the base of band B 

 he found a species of Obolus which he described as Oboluspulcher. ] This 

 comprises the Lower Cambrian fauna or pre- Paradox ides fauna as 

 known to him from New Brunswick up to date. 



In another paper on the u Cambrian organisms in Acadia," pub- 

 lished in the same year, he notes the discovery in the lower beds of the 

 St. John section, beneath the Paradoxides beds, of several varieties of 

 gponges, a species of Palaeochorda and another undescribed species. 

 Undoubted examples of Platysoleuites of Pander also occur. 2 Men- 

 tion is made of the discovery above the Paradoxides zone in the Olenus 

 horizon, of three species of fossils, and above this another stage which he 

 has placed under the title of Peltura beds, corresponding in age to the 

 Cape Breton Upper Cambrian beds. 



In September, 1889, Mr. Matthew 3 argues for the uniting of the 

 Olenellus or Lower Cambrian, and the Paradoxides or Menevian zone, 

 as one division of the Cambrian, and the strata above the Paradoxides 

 zone as the upper division, thus returning to the classification of Salter 

 and Hicks, adopted for the Cambrian strata of Wales. 



The full text of Mr. Matthew's paper on the Cambrian organisms in 

 Acadia was distributed in June, 1890. It deals almost entirely with 

 the pre-Paradoxides or Basal series of the Cambrian section of New 

 Brunswick, and is accompanied by both tabulated and illustrated sec- 

 tions and sketch maps of Hanford Brook and Catou's Island. 4 It is 

 referred to at length in the description of the Cambrian rocks of New 

 Brunswick in this paper (Chapter, iv). 



In a paper read May 28, 1890, Mr. G. F. Matthew gives a detailed 

 description of the geologic structure of the St. John basin in connection 

 with three sections crossing it. Further notice of it will be found in 

 the summary of our present knowledge of the St. John terraue of New 

 Brunswick. 5

 Canada, Dr. George M. Dawson tabulates the Cambrian as follows: 6
