INTRODUCTORY. 



The bituminous shales of Albert county, New Brunswick, apart from their commercial 

 value, have long been noted for their well preserved remains of fishes belonging to the family 

 Palseoniscidse. Since the publication, in 1851, of Dr. Charles T. Jackson's descriptions of Albert 

 mine fishes, this particular fauna has not received the attention that it deserves. A thorough 

 knowledge of the character and structure of the various species represented is of importance, 

 as an aid in the determination of geological horizons in New Brunswick and Nova Scotia. 



In the following pages will be found the results of a study, by Mr. Lawrence M. Lambe, 

 of the Albert shales fish fauna, based on the large collections of specimens from the typical 

 locality and its neighbourhood, in the possession of the Geological Survey, and on type material 

 and well preserved specimens from the same localities kindly loaned by the Museum of Com- 

 parative Zoology, Cambridge, Mass.; the Boston Society of Natural History; McGill University; 

 and the Natural History Society of New Brunswick. 



Mr. Lambe's memoir forms part V of volume III (quarto) of 38 pages of text with eleven 

 full-sized photogravure plates.
