306 Mr J. D. Dana on Nomenclature in Natural History. 



§ 8. It is recommended that generic names, and specific 

 names which are derived from names of persons, be written 

 with an initial capital ; that all other specific names be 

 with a small initial letter. 



This principle is introduced with reference to names of 

 this kind already in use ; for it is to be hoped that they may 

 not be added to in future. (§ 6, c.) 



§ 9. It is recommended that the original authority of a 

 species always follow the name in brackets ; and if the name 

 be subsequently altered, the authority for the same as altered, 

 be added without brackets. 



It has been common for systematists to change a generic 

 name, and then to add their own name to all the species. 

 To prevent this injustice, which is no less than a kind of 

 piracy, the above rule is proposed. As an example — the 

 Tyrannus crinitus of Swainson is the Muscicapa crinita of 

 Linnaeus : to distinguish here the author of the former 

 name, and give due justice to Linnaeus, it may be written 

 Tyrannus crinitus^ (Linn.) Swain. By this we do not inti- 

 mate whether the genus Tyrannus is Swainson' s or not ; 

 it is sufficient for the purposes of science to shew here that 

 the above title, as a whole, was first adopted by Swainson. 

 The authority for the genus will be found elsewhere. 



§ 10. It is recommended that when an author, through 

 ignorance of what his predecessors have done, gives to a 

 species an appropriated specific name, the name of such 

 author be omitted. 



§ 11. It is recommended that when an author only cor- 

 rects a false orthography, his name be not added as 

 authority for the corrected term. 



§ 12. It is recommended that in subdividing a genus, the 

 new generic names proposed for the subdivisions formed, agree 

 in gender with that of the original genus. 



§ 13. It is recommended that in proposing new genera, 

 the etymology of the names be always stated ; and that one 

 species be pointed out as a type or standard of reference. 



§ 14. It is recommended that new genera and species be 

 amply defined, and that the descriptions be inserted in such
