THE GENERIC NAME PASSERINA, 185 
NOTE XVII. 
ONCE MORE THE GENERIC NAME 
PASSERINA VIEILLOT 
BY 
Dr. E. D. VAN OORT. 
The note on the generic name of the Snow-bunting by 
Dr. EK. Hartert in this part of our periodical gives me 
cause to revert to the subject of my note on the generic 
name Passerina Vieillot and to state here, that I stand 
to what I have said about the rejection of this name in 
Zoology (Notes Leyden Mus. XXXII, n°. 1, p. 32). Dr. 
Hartert says, that all modern codes of nomenclature in 
Zoology have agreed not. to consider botanical nomenclature. 
This may be so, but I ask here, are Zoologists and 
especially Ornithologists agreeing in nomenclature? 
The answer is in the negative. When studying papers on 
systematic Ornithology by different authors we learn that 
they agree but very little in naming the forms. Hach 
author seems to have his own views and seems to follow 
different rules. There is no agreement at all, even not 
with authors, which follow the same code. So it will remain, 
I am sure, always. This is indeed a proof, that many 
author cannot agree with every rule of nomenclature fixed 
by the different committees. 1 do not wonder at it, as 
there are rules, which are not acceptable, f.i. the rule, 
that botanical nomenclature should not be considered in 
Zoology. The practice of this rule can cause confusion and 
therefore it is certainly better to consider botanical nomen- 
clature in Zoology. Moreover, where is the line between 
Zoology and Botany? 
As to the type of the genus Passerina Vieillot, I differ 
with the view of Dr. Hartert, which is in my opinion
