authors. Artedi especially has put the nomenclature of his 

 branch of science, Ichthyology, in a clear system. We read, 

 for instance, in his 'Philosophia Ichthyologica ' (p. 64), 1738, 

 the following thesis : " Nomen Genericum est vocabulum 

 illud, quo omnes species, ad unum genus pertinentes, in- 

 signiuntur"; and, further on in the same work (p. 80), 

 " Nomen specificum est Epithetou illud aliquot vocabulis 

 constans, quod noraini Generico postpouitur, ut una species 

 Piscium a reliquis Ejusdem Generis diguoscatur.'^ This is, 

 I think, clear enough *, but, in spite of it all, the generic 

 names found in such older works have not been claimed as 

 valid — if they have not independently been taken up by 

 later authors, — although they are analogous to those of 

 Gronovius. This fact also supports my view that only 

 binominal authors have the right to be considered in modern 

 nomenclature. 



As a conclusion of the above, I insist that : — 



(1) The word " bbiary" in Article 25, h, of the Inter- 

 national Rules of Zoological Nomenclature must be under- 

 stood as equivalent with binominal, and every attempt at 

 giving binarr/ in connection with the words "uame''^ or 

 " nomenclature " in zoological literature any other meaning 

 is of no avail, as being based neitlier on etymological nor 

 on historical facts, nor on usage. 



(2) '^ Opinion 20 '^ of the International Commission on 

 Zoological Nomenclature, as being based on a misinterpreta- 

 tion of the word " binary, ^^ must be declared void, and the 

 same must be the case with " Opinion 37 " and any other 

 Opinion which has been based on the same premises.

Since the publication in 1880 of Capt. F. W. Hutton's 'Manual of 

 the New Zealand MoUusca ' a very considerable number of species 

 lias been added to the New Zealand fauna. At that date only just 

 450 forms were known, now close on 1190 are recognized. The

 we should have had the modern nomenclature introduced already in 

 1738.
