These names are formed by changing the last syllable of the geni- 

 tive into idee or ina ; as Strix gives Strigida, from the genitive Stri- 

 gis, Buceros gives Bucerotidce, from the genitive Bucerotis ; not 

 Bucerida. 



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 written 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 injus- 

 tice, 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 LINN.EUS : to distinguish here the author of the former name 

 and give due justice to LINN.EUS, it may be written, Tyrannus crinitus^ 

 (LiNN.) SWAIN. By this we do not intimate whether the genus Tyran- 

 nus is SWAINSON'S or not; it is sufficient for the purposes of science to 

 show here that the above title, as a whole, was first adopted by SWAIN- 

 SON. 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 corrects a false or- 

 thography, 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 etymol- 

 ogy 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 de- 

 fined, and that the descriptions be inserted in such periodical or other 

 works as are likely to obtain immediate and extensive circulation.
