PREFACE. IX 



3. That the names should be formed on the analogy 

 of existing Greek or Latin words : but that it is ad- 

 visable to maintain a uniformity of -termination through- 

 out each Tribe, to assist the memory. 



4. Names taken from localities commonly become 

 inappropriate, from the occurrence of the species in 

 other places : and names taken from persons should not 

 be lightly applied. This distinction should be reserved 

 for those whose works and scientific labours give them a 

 claim to the admiration of posterity. 



November 1858. 



For, specific (from species, facere) is that which makes a thing of the 

 species of which it is ; while that which notes a species is special. Thus, 

 " special name," not " specific name," is strictly correct. Since both 

 these adjectives are in common use, with significations different from one 

 another and from either of the above, it would perhaps be well (if the 

 compound "species-name " be considered open to objection) to retain the 

 Linnaean designation "trivial name."
