42 International Code of Nomenclature 



Recommendation 6b. Sect. 1. Naming of Taxa 



Reconiinendation 6b (6) . This recommendation, found necessary in 

 botany, has rarely, if ever, been of significance in bacteriology. 



Rccommcndatioyi 6b (7) . Many such hybrid words used as specific 

 epithets have been proposed, as acidophilus (acid-loving) , nlbo- 

 chryseus (whitish golden) . 



Additional Recommendations of the Botanical Code. The Botanical 

 Code includes several Recommendations relating to specific epithets 

 that are of interest. The Botanist is urged: 



(a) To use Latin temiinations insofar as possible. 



(d) To avoid those formed of two or more hypliened words. 



(e) To avoid those which have the same meaning as die generic 

 name (pleonasm) . 



(h) To avoid those which haAe been used before in any closely allied 

 genus. 



Additional Recommendations from the Zoological Rules are also 

 pertinent. 



(1) The best specific name (epithet) is a Latin adjective, short, 

 euphonic, and of easy pronunciation. Latinized Greek words 

 or barbarous words may, however, be used. Examples: gym- 

 nocephalus, echinococciis, agnti, koactli, urubitinga. 



(2) It is well to avoid the introduction of the names (epithets) 

 typicus and typus as new names for species or subspecies, 

 since these names are always liable to result in later con- 

 fusion. 



(3) The use of compound proper names indicating dedication, 

 or of compound words indicating a comparison with a simple 

 object, does not form an exception to Art. 2. In these cases 

 the two words composing the specific name (epithet) are 

 written as one word with or without the hypen. Examples: 

 sanctae-catharinae or sanctaecatliarinae , jan-maveni or 

 janmaveni, cornu-pastoris or cornupastoris, com-anguinum or 

 cornanguiniim, cedo-nulli or cedonulli. 



(4) Expressions like rudis planiisque are not admissible as spe- 

 cific names (epithets) .
