COMMISSION ON ZOOLOGICAL NOMENCLATURE. OPINION 184 



(v) In Order to secure availability under Article 25, any manuscript 

 generic name published by Martini and Chemnitz in volumes i-ii 

 of the Conchylien-Cabinet will need to be accompanied by an indica- 

 tion (as defined in Opinion i 1») or by a definition or by a description. 

 (vi) Of the points enumerated in (iv) above, point (a) eliminates all 

 names for which no indication, definition or description is given ; 

 point (e) eliminates such names as Nux and Gallina (see paragraph 

 I (b) above) ; and point (f) " eliminates from consideration a name 

 such as Fiisus where that name is used as a group-name in the 

 nominative plural only (see paragraph i (a) above) . 

 (vii) An inspection of volumes i-ii of the Conchylien-Cabinet suggests 

 that, after the principles set out in (iv) above have been applied — 

 as they must be — to any new generic or sub-generic name published 

 in that work, the number of such names which will be found to be 

 available under the Code will be very small. 



6. By October 1936 a sufficient number of Commissioners had 

 recorded their votes in favour of the proposed Opinion in Order to 

 secure its adoption as an Opinion of the Commission. The papers 

 relating to the present case were among the first to be transferred 

 from Washington to London after the election (on 6th October 

 1936) of Commissioner Hemming to be Secretary to the Com- 

 mission and on 3 ist December 1936 Commissioner Hemming, 

 acting in virtue of the powers conferred upon him in that behalf 

 by Article 7 of the By-Laws, closed the ballot in this case. 



III.^THE CONCLUSION REACHED BY THE INTERNA- 

 TIONAL COMMISSION. 



7. The decision taken by the Commission in the present case 



(a) that, for so long as generic names published by authors using a System 

 of nomenclature which, though not binominal, is of the type hitherto 

 accepted as falling within the definition of binary nomenclature, are 

 accepted as complying with the requirements of Article 25 of the 

 International Code, any new generic name published in volumes i 

 to II of Martini (F. H. W.) and Chemnitz (J. H.) Neues systematische 

 Conchylien-Cabinet, Nürnberg, 1 769-1 795, is to be accepted as avail- 

 able nomenclatorially, but that the position should be re-examined if 

 later it is decided to reject generic names published by authors not 

 applying the binominal System ; 



(b) betöre a new name published by Martini and Chemnitz in the volumes 

 referred to above is accepted as available as a generic or sub-generic 

 name as from the date of such publication it will be necessary to 

 establish that it satisfies the provisions of the Code in all respects, for 

 example : 



(i) that it was accompanied by an indication as defined in Opinion i 



or a definition or description ; 

 (ii) that, if a pre-1758 name, it complies with the provisions of 

 Opinion 5 ;
