Young fish are rarely taken, and those under a foot in length, never. 
Some Proposed Changes in the Nomenclature of the 
American Mammalia.—The changes in nomenclature herein pro- 
posed are the outcome of a critical study of the literature and synon- _ 
ymy relating to the Mammals of Ord’s Zoology, which was published 
in Philadelphia in 1815, in the second American edition of Guthrie’s 
Geography. 
As already announced in Tue Narura.ist (March, 1894, p. 289), 
a reprint of a recently discovered copy of this extinct work will be 
shortly issued by the subscriber. In an appendix to this reprint the 
following emendations are-fully discussed. For several of these no 
claim of originality is pretended, as they only reaffirm the decisions of 
others which have not hitherto met with general acceptance, but which, 
after a very careful examination, appear to merit the endorsement 
of scientists. The Code of the American Ornithologists Union has been 
made the basis of these determinations. ;
