452 MELVILL: THE PRINCIPLES OF NOMENCLATURE. 
committee was appointed, at the Meeting in Newcastle in 1863, 
consisting of Sir W. Jardine, Bart., Messrs. A. Russel Wallace, 
C. Spence Bate, Philip P. Carpenter, J. E. Gray, C. Babington, 
D. Francis, Philip Lutley Sclater, Sir J. D. Hooker, J. H. Bal- 
four (of Edinburgh), H. T. Stainton, J. Gwyn Jeffreys, A. New- 
ton, T. H. Huxley, G. J. Allman, and G. Bentham. 
The actual work of revision seems to have been carried 
out by four of these gentlemen, viz. Gwyn Jeffreys, A. R. 
Wallace, P. L. Sclater, and Sir Wm. Jardine as reporter. 
The chief alterations and emendations, as given on p. 28 
of the Report of the British Association for 1865, held at 
Birmingham, are as follows :— 
(I.) That Botany should not be introduced into the 
Strickland rules and recommendations. 
(II.) ‘That the permanency of names and convenience of 
practical application being the two chief requisites in any code 
of rules for scientific nomenclature, it is not advisable to dis- 
turb by any material alterations the rules of Zoological 
nomenclature which were authorized by Section D at the 
meeting of the British Association in Manchester in 1842. 
(III.) ‘That the Committee are of opinion, after much 
deliberation, that the XII edition of Linné’s “Systema Naturee,” 
1767, is that to which the limit of time should apply. But as the 
works of Artedi and Scopoli have been already extensively used 
by entomologists and ichthyologists, it is recommended that 
the names contained in or used from these authors should not 
be affected by this provision. ‘This is particularly requisite as 
regards the generic names of Artedi used by Linnzeus himself. 
Besides these three recommendations, it was proposed that 
(a) it was extremely injudicious to adopt a specific name as a 
generic, but that when this had been done, it was the generic 
name, not the specific, which should be thrown aside, and that 
the Stricklandian rule as to this should be altered.
