SCIENCE 



[N. S. Vol. XXXII. No. 818 



eating with the fifteen commissioners, it was 

 impossible to act promptly upon these cases, 

 but in the winter of 1909-10 the Smithsonian 

 Institution gave a grant to provide for the 

 clerical work, and since that time it has been 

 possible to render the opinions more promptly. 



The commission has no legislative power. 

 Its powers are restricted to studying questions 

 of nomenclature, to reporting upon such ques- 

 tions to the International Congress and to 

 rendering opinions upon cases submitted to it. 



The Smithsonian Institution has now un- 

 dertaken the publication of these opinions up 

 to a certain point. Publication No. 1938 en- 

 titled " Opinions Eendered by the Interna- 

 tional Commission on Zoological Nomencla- 

 ture," has just been issued and gives the first 

 twenty-five opinions prepared by the commis- 

 sion. 



The following is the method to be adopted 

 in submitting cases for opinion, and zoologists 

 will aid the coimnission in its work if they 

 wiU bear in mind the following points: 



1. The commission does not undertake to 

 act as a bibliographic or nomenclatural bu- 

 reau, but rather as an adviser in connection 

 with the more diificult and disputed cases of 

 nomenclature. 



2. All eases submitted should be accom- 

 panied by (a) a concise statement of the point 

 at issue; (b) the full arguments on both sides, 

 in case a disputed point is involved, and (c) 

 complete and exact bibliographic references to 

 every book or article bearing on the point at 

 issue. The more complete the data when the 

 •case is submitted, the more promptly can it 

 be acted upon. 



3. Of necessity, cases submitted with in- 

 complete bibliographic references can not be 

 studied, and must be returned by the commis- 

 sion to the sender. 



4. Cases upon which an opinion is desired 

 may be sent to any member of the commission. 



5. In order that the work of the commission 

 may be confined as much as possible to the 

 more difiicult and the disputed cases, it is 

 urged that zoologists study the code and settle 

 for themselves as many cases as possible.
