THE AMERICAN NATURALIST 



[Vol. XLV 



discussed Russo's data. Two independent repetitions of his 

 breeding experiments, one made in Italy, the other in England, 

 have failed to confirm his conclusions, which therefore, as matters 

 stand, have slight weight.

NOTES ON ICHTHYOLOGY 



In the Abhandlungrn of the Akadcmic dcr \Yiss< nsehaften, in 

 Bavaria, Vol. IV, Munich, 1910, Victor Franz has an elaborate 

 account of the bony fishes collected in Japan by Haberer and 

 Doflein. This is an important paper, containing descriptions 

 and figures of numerous new species. 



In the Contributions from the Zoological Laboratory of 

 Indiana University, No. 76, part 2, Dr. Carl H. Eigenmann gives 

 a "Catalogue and Bibliography of the Fresh-water Fishes found 

 in Tropical and South Temperate America, ' ' including all south 

 of the latitude of the mouth of the Rio Grande. Dr. Eigenmann 

 gives a discussion of the valid reasons which have led him to 

 retain the generic n;mic Juptidi ns in place of Acara. 



In the Bulletin of the Bureau of Fisheries, Vol. XXIX. 1909, 

 Jordan and Evermann discuss the "Salmonoid Fishes of the 

 Great Lakes," with numerous plates, some of them in color. 

 The name Leucichthys of Dybowski is adopted in place of the 

 earlier name. Arggrosomus, of Agassiz. which was first used for 

 a marine fish. Four new species of Leucichthys or lake herring 

 are described. L. supernas from Lake Superior. L. eyauopterus 

 from Lake Superior, L. manitoulinus from Lake Huron, and 

 L. ontariensis from Lake Ontario. A new variety. L. harengus 

 arcturus, is described from the west end of Lake Superior. Two 

 new sub-generic names are adopted: Thrisso»ii»ius Gill for the 

 ordinary lake herring, the name Arggrosomus being preoccu- 

 pied; and Cisco for the deep-water forms.. In this paper it is 

 shown that the shore lake herring, instead of constituting a 

 single species, are really several in number, at least six of them 

 in the Great Lakes deserving recognition as species. 



In the Bulletin of the Bureau of Fisheries, Vol. XXIX, 

 1909, Dr. Charles W. Greene discusses in detail the migration 

 of the salmon in the Columbia River, treating with considerable 

 fullness the methods by which individuals may be marked.
