modulus and P. jacksonii. The type material of the former 

 species was from Beliveau in the northeastern continuation of 

 the Albert shales area and about six miles, in a straight line, 

 from the Albert mines ; the latter species was based on one 

 of Dr. Jackson's largest specimens from the Albert mines 

 (Palceoniscus sp., fig. 4 of Jackson's original plate I) in con- 

 junction with specimens from the same locality in Dawson's 

 collection and in that of Dr. G. F. Matthew of St. John, N. B. 



Sir Philip Gray Egerton,* and much later Dr. John Strong 

 Newberryf and Dr. Arthur Smith Woodward, J and recently 

 Dr. Charles R. Eastman, § have referred to all or some of 

 these species in greater or less detail. 



In a paper, to be published shortly by the Geological Survey 

 of Canada, on the " Palseoniscid Fishes of the Albert Shales 

 of New Brunswick," the writer gives the result of a study of 

 the fish fauna of the shales of Albert mines and vicinity as 

 revealed by the collections of the Geological Survey and by 

 Jackson's and Dawson's type material. The writer takes this 

 opportunity of expressing his thanks to Dr. Charles R. East- 

 man and Mr. Samuel Henshaw of the Museum of Comparative 

 Zoology, Cambridge, Mass., to Mr. Charles W. Johnson of the 

 Boston Society of Natural History, to Dr. Frank D. Adams 

 of McGill University, and to Dr. G. F. Matthew of St. John, 

 ~N. B., for the highly valued loan of Dr. Jackson's and Sir J. 

 William Dawson's type and other specimens, without which 

 the study of this interesting fauna could not have been pro- 

 perly undertaken. 



The Albert shales, primarily held to be of Lower Carbonif- 

 erous age, principally on the evidence of their fossils, both 

 vegetable and animal, have of late been regarded by some 

 Canadian geologists of repute as properly belonging to the 

 Devonian. ' 



The great similarity of the fauna of the Albert shales of New 

 Brunswick to that of the shales of the Calciferous Sandstone 

 Series of Scotland is clearly apparent from the first to any 

 one studying them and would convince most observers that 

 these fish-bearing beds in the two countries are synchronous 

 and belong to the same horizon. The genera of Palseoniscidse 

 of the Albert shales of New Brunswick are the same as those 

 of the Scottish shales ; the difference is apparent only in the 

 species, and in these there is a remarkable general resemblance. 

 The Calciferous Sandstone Series is held by the Geological 

 Survey of the United Kingdom to form the base of the Car-
