306 THE CANADIAN NATURALIST. [Jan. 



by F. W. Putnam, Superintendant of the Essex Institute. — A list 

 numbering 45 species of true lake fishes, obtained by the author 

 from Lake Champlain, was given; of these, 41 were found by him 

 in Lake Erie. As Lake Champlain was a salt-water bay at a 

 period subsequent to the glacial epoch, while the lakes above 

 Niagara Falls contained fresh-water, the weight of evidence goes 

 to support the conclusion that the fishes of Lake Champlain have 

 been chiefly derived from those higher lakes. 



Among other business transacted before the close of the 

 meeting, the following resolution was moved by Prof. 0. C. Marsh. 

 and adopted: — 



"Resolved, That the chair appoint a commission of nine 

 members to examine the Linnean rules of Zoological Nomenclature 

 by the light of the suggestions and examples of recent writers, and 

 to prepare a code of laws and recommendations in conformity 

 with past modern usage, to be submitted to the Association at the 

 next annual meeting ; the committee to have authority to fill 

 vacancies and increase the number to twelve, if deemed advisable." 



The committee appointed consists of: — Prof. J. D. Dana, of 

 Yale College ; Prof. Jeffries Wyman. of Howard University ; 

 Prof. S. F. Baird, of the Smithsonian Institution; Prof. Joseph 

 Leidy. of the Philadelphia. Academy of Natural Sciences ; Prof. 

 J. F. Newberry, of Columbia College; Principal Dawson, of 

 McGill University, Montreal ; Dr. Wm. Stimpson, of the Chicago 

 Academy of Science; S. H. Scudder, of the Boston Natural 

 History Society ; and F. W. Putnam, of the Essex Institute. 



The next meeting will be held at Chicago, commencing on the 

 first Wednesday of August, 1868. II.

 Since the subject of Laurentian fossils was placed before this 

 Society iu the papers of Dr. Dawson, Dr. Carpenter, Dr. T. Sterry 

 Hunt, and myself, in 1865, additional specimens of Eozoon have 

 been obtained during the explorations of the Geological Survey of 

 Canada. These, as in the case of the specimens first discovered, 

 have been submitted to the examination of Dr. Dawson ; and it 

 will be observed, from his remarks contained in the paper which is
