In 1891, in part II of the "Catalogue of the Foswil Fishes in the British Museum," Dr. Arthur 

 Smith Woodward supplied brief descriptions of three of thcsc! species, under the names Rhadini- 

 chthys alherti, (Jackson), R. coir/i.si (Jackson), emd R.modidua (Dawson). Elonichthys browni 

 (p. 501) is mentioned under doubtful and imperfectly defined sp(^cies. 



Lately Dr. Charles R. Eastman, in his Devonian Fishes of Iowa (Iowa Geological Survey, 

 volume XVIII, 1908), has included references to Rhadinichthys alberii, R. cairn&i, a,ndR. modulus, 

 specifying these species as from the lower Carboniferous of Albert county, N.B. 



The foregoing are the principal references to the fishes from the Albert shales since the 

 original descriptions appeared in 1851, a period of nearly sixty years. Jackson's plates of figures, 

 although a few copies may have been "distributed, were not available to most paleontologists. 

 The fortunate discovery by Dr. Eastman of Jackson's original drawings has made possible the 

 recognition of the types and figured specimens. 



Collections — Acknowledgments — Type iwaterial loaned . 



The Geological Survey of Canada received, in the autumn of 1907, two large collections of 

 fishes from the Albert shales of New Brunswick, one made by Dr. R. W. Ells, of this Survey, 

 the other by Mr. James Robertson, of the Albert mines. 



With a view to reporting on the Albert shales fish fauna generally, the writer, in January, 

 1908, turned his attention to these collections, and to the material from the typical locality 

 and vicinity already in the museum of the Geological Survey, collected principally by Dr. R. 

 W. Ells in 1876, by Dr. F. D. Adams in 1877, and by Mr. James Robertson in 1891. There is 

 also now available for study the large collection made at the same locahty by the writer, during 

 the summer of 1908. 



My thanks are respectfully tendered to Dr. Frank D. Adams of McGill University, to Dr. 

 Charles R. Eastman and Mr. Samuel Henshaw of the Museum of Comparative Zoology, Cam- 

 bridge, Massachusetts, to Mr. Charles W. Johnson of the Boston Society of Natural History, 

 and to Dr. G. F. Matthew, St. John, N. B.; to Dr. Adams for affording me the opportunity 

 of examining the type specimen of Dawson's Palaonricus (Rhadinichthys) modulus and other 

 specimens of Albert shales fishes from New Brunswick, the property of the Peter Redpath 

 Museum, Montreal; to Dr. Eastman and Mr. Henshaw, for the loan of Jackson's type, and figured 

 specimens that belong to the Museum of Comparative Zoology, and also for the much appreciated 

 gift of photographs of Jackson's original drawings for his two plates; to Mr. Johnson for the loan 

 of Albert Mines fish material, the property of the Boston Society of Natural History, in which 

 are included the originals of threes of Jackson'g figures; and to Dr. Matthew for having kindly 

 placed in my hands a number of specimens, from the Albert mines, belonging to the Natural 

 History Society of New Brunswick.
