456 MELVILL: THE PRINCIPLES OF NOMENCLATURE. 
Mr. Dall includes Botanical Nomenclature as well as 
Zoological in his lengthy report which follows ; for the former 
largely quoting and adhering in the main to De Candolle.* 
With regard to the date of the starting point of Binomial 
Literature and Nomenclature, he conforms, as regards Zoology, 
to the date of the XII. Edition of the “Systema Naturze,” 
1766-67. In Botany, the date of the “Species Plantarum” of 
Linneus, 1753. 
The following restrictions, as concerning Zoology, now 
follow :— 
(i). That specific names shall in no case antedate the 
promulgation of the Linnzean rules (“ Philosophia Botanica,” 
1751), that (11) until the formal notice by publication of the deci- 
sion of such associated specialists (in such manner as may be 
by them determined upon) shall be decisively promulgated, the 
adoption of the epoch as starting point recommended by the 
Committee of the British Association in 1842, viz.:—the XII. 
Edition of the ‘‘ Systema Naturee” shall be taken as the estab- 
lished epoch for all Zoological Nomenclature. 
It is pointed out by Prof. Verrill and others how much 
better the date of the tenth edition would have been, as especially 
in Arachnida and Entomology, certain authors are in danger of 
having their names repudiated, who published between 1758 
and 1767. 
It is likewise shewn that some authors, such as Mr. G. R. 
Gray in his ‘‘Genera of Birds,” adopt the I. Edition of the 
“Systema,” (1735) for genera, the X. for specific names (1758). 
VI.—La SocIETE ZOOLOGIQUE DE FRANCE, 1881. 
In 1881 the Société Zoologique de France published the 
results of the Commission appointed by that body to investi- 
gate the question of nomenclature. This Commission was com- 
posed of Messieurs E. Simon, F. Lataste, L. Chaper, Kiinckel 
* A. de Candolle, Lois de la nomenclature botanique, rédigées et commentées, Paris, 1867.
