names on basis of the Law of Priority, 45 of the 50 names (or 90 per cent) 

 changed from 1859 to 1886. From 1886 (when the names were established 

 on basis of the Law of Priority) to 1895, not one of the 50 names was 

 changed. The complete list embraced 322 genera and about 1000 species 

 and subspecies. In the 10 yeai's following the publication of the list (based 

 upon Priority), it was found necessary to change, by action of the Law of 

 Priority, the names of 3 genera, 1 subgenus, 3 species, and 1 subspecies. 



49) The Commission invites the serious attention of the Congress to 

 these very remarkable results obtained by the Code of the A. 0. U. If our 

 International Code is properly safeguai-ded against changes taken hastily 

 and without due deliberation as to the many complications involved, it may 

 reasonably be expected that our International Official List will undergo 

 very few changes upon nomenclatorial grounds, but this Commission can 

 not possibly foresee what changes must be adopted during the next 10 to 

 100 years because of unforeseen changes in conceptions of classification. 



50) The Commission has the honor to request definite instructions 

 from the Congress as to whether or not it is the desire to have this list con- 

 tinued. 



51) Code of Ethics. — The Commission permits itself to invite at- 

 tention to the fact that there exists in the zoological profession no recognized 

 and generally adopted Code of Ethics that is comparable to the Code of 

 Ethics existing in the medical profession of certain coutries. "Without pi-e- 

 suming to be the arbiter of points of general ethics, the Commission is per- 

 suaded that there is one phase of this subject upon which it is competent to 

 speak and in reference to this point it suggests to the Congress the adoption 

 of the following resolution: 



52) Whereas, Experience has shown that authors, not infrequently, 

 inadvertently publish as new designations of genera or species names that 

 are preoccupied, and 



Whereas, Experience has also shown that some other authors dis- 

 covering the homonymy have published new names for the later homonyms 

 in question, be it therefore 



Pesolved, That when it is noticed by any zoologist that the generic 

 or the specific name published by any living author as new is in reality a 

 homonym and therefore unavailable under Articles 34 and 36 of the Rules 

 on Nomenclature, the proper action, from a standpoint of professional eti- 

 quette is for said person to notify said author of the facts of the case and to 

 give said author ample opportunity to propose a substitute name. 



53) Date of Author's reprints or sep arata. — Among the cases 

 recently submitted to the Commission for Opinion is one that involves a 

 somewhat unusual point in respect to reprints. Under the present rules 

 there is no article which permits the Commission to rule that all se^iarata 

 are of the same date as, or of a later date than, the original publication, 

 although such a proposal has now been submitted as an amendment to the 

 rules and will be considered in time for the Tenth Congress. In the mean- 

 time, the Commission has instructed the Secretary to report the following 

 resolutions to the Congress: 



54) Resolved, That the Commission, under unanimous suspension 

 of the By-Laws, if need be, recommends to the Congress the adoption of 

 the following resolution, namely.
