292 The American Naturalist. [Mareh, 
The Botanical Club of the American Association for the 
Advancement of Science at a meeting held Aug. 19, 1892, adopt- 
ed these principles of Nomenclature: Resolved: That the Paris 
code of 1867 be adopted except where it conflicts with the following: 
I. The Law of Priority. Priority of publication is to be regarded as 
the fundamental principle of botanical nomenclature. II. Beginning 
of Botanical Nomenclature. The botanical Nomenclature of both 
genera and species is to begin with the publication of the first edition | 
of Linnzus “Species Plantarum,” in 1753. III. Stability of Specifie 
Names. In the transfer of a species to a genus other than the one 
under which it was first published the original specific name is to be 
retained, unless it is identical with the generic name or with a specifie 
name previously used in that genus. IV. Homonyms. The publica- 
tion of a generic name or a binominal invalidates the use of the same 
name for any subquently published genus or species respectively. V. 
Publication of Genera. Publication of a genus consists only (1) ia 
the distribution of a printed description of the genus named. (2) im 
the publication of the name of the genus and the citation of one or 
more previously published species as examples or types of the genus, 
with or without adiagnosis. VI. Publication of Species. Publication 
of a species consists only (1) in the distribution of a printed descrip- 
tion of the species named, (2) in the publishing of a binominal, with 
reference toa previously published species asa type. VII. Similar 
Generic Names. Similar generic names are not to be rejected on 
account of slight differences, except in the spelling of the same word; 
for example Apios and Apium are to be retained, but of Epidendrum 
and Epidendron, Asetrocarpus and Astrocarpus, the later is to be rejected 
VIII. Citation of Authorities. In the case of a species which has 
been transferred from one genus to another the original author must 
always be cited in parenthesis, followed by the author of the nee 
binominal. N. L. Britton, John M. Coulter, Henry H. Rusby, Wil- 
liam A. Kellerman, Frederick V. Coville, Lucien M. Underwood, 
Lester F. Ward, Committee. 
At the meeting of the New York Academy of Sciences to be held on 
March 5th prox., will. be held a debate between the supporters of the 
Neodarwinian and Neolamarckian theories of organic evolution. Prof. 
E. 8. Poulton, of the University of Oxford, England, will open for 
the former, and Prof. E. D. Cope, of Philadelphia, will reply for the 
latter. Profs. W. B. Scott, of Princeton, and E. B. Wilson of New 
York, -will also speak. 
Prof. W. P. Wilson has brought to Philadelphia twenty-four cat 
loads of exhibits, mostly of natural objects, which were displayed at 
the Chicago Exposition.
