individual prejudices, of personal caprice, of neglect, of lack of 

 courage. Repeated instances might be cited of men who knowing 

 a thing was wrong, pointed it out, and not only left it uncorrected, 

 but also continued its use themselves. 



The principle, therefore, is in theory, rigid; in practice more 

 flexible than a serpent and more tortuous than a maze. In order 

 to render it that firm foundation for nomenclature it was intended 

 to be, wise rules should be formulated defining its scope and restrict- 

 ing its workings, if necessary. It should be rendered impossible 

 for zoologists to make any emendations, classical or otherwise; 

 fixed rules for determining priority should be adopted ; a restriction 

 should be placed on revival of old names of doubtful validity; 

 steps should be taken to do away with species unrecognizable 

 without the types; and above all, human nature should be reformed 

 and perfected, and every nomenclatorialist should be endowed 

 with keenness of understanding, logic, unselfishness and imparti- 

 ality, in order to apply the law of priority with even-handed 

 justice. When this ideal is attained, then nomenclature will be 

 on a firm foundation. 



Observe the law impartially, enforce the law rigidly, there 

 lies the one and only road to a stable nomenclature.

Table of Hickory Leaf Midge Galls. 



By E. P. Felt, Albany, N. Y. 



Hickory or Carya comprises a number of closely related 

 species well separated from other members of the flora. Our 

 studies of gall midges have shown the genus Caryomyia to be 

 confined to Carya upon the leaves of which a number of closely 

 related midges produce very similar galls. 



This table is designed to assist in the identification of the 

 species by characters found in the galls and larvae. It should be 

 considered as tentative and suggestive rather than as final, owing 

 to the variations in the galls and the difficulty of finding satis- 

 factory specific characters in the larvse. It is probable that other 

 species of Caryomyia, aside from those tabulated below, will be 

 found to inhabit the hickory. Certain species are tentatively 

 assigned to this genus.
