NOMENCLATURE RULES. -The Nomenclature adopted in The Naturalist will be 

 —as far as possible — in accordance with the latest standard list or monograph, with such 

 alterations as are necessary to bring the name into accordance with the strict law of 

 priority. 



CAPITALISATION OF SPECIFIC NAMES -Hitherto the rule of The Naturalist has 

 been the Zoological one, that specific names shall invariably commence with a small 

 letter, never with capitals. Henceforth this rule will still apply to all Zoological names, 

 but in deference to the wishes of our botanical contributors the specific names of plants 

 will conform in this respect to the standard catalogue or monograph in each branch 

 of botany.
