b. Compound Greek words, in which the attribute should precede the principal 

 word. Examples : Sleiiogyra, Pleurobranckns, Tylodina, Cyclostoiniim^ Sanocystis, 

 Pelodyfes, Hydropkihis, Rhizobiiis. 



This does not, however, exclude words formed on the model of Hippopotamus, 

 namely, words in which the attribute follows the principal word. Examples : 

 Philydrus, Biorhiza. 



c. Latin substantives. Examples : Ancilla, Auricula, Dolium, Harpa, Oliva. 

 Adjectives (Prasina) and passed participles {Produdus) are not recommended. 



d. Compound Latin words. Examples : Stiliger, Dolabrifer, Seniifustis. 



e. Greek or Latin derivatives expressing diminution, comparison, resemblance, 

 or possession. Examples : Dolium, Doliohim ; Strongylus, Eustrongylus ; Limax, 

 Limacella, Limacia, Limacina, Linuicites, Limacula ; Lingula, Lingulella, Lingu- 

 lepis, Linguliiia, Liiigulops, Liiigulopsis ; Neomenia, Proneomenia ; Buteo, Archi- 

 buteo ; Gordius, Paragordius, Polygordius. 



f. Mythological or heroic names. Examples : Osiris, Venus, Brisinga, Velleda, 

 Crimora. If not Latin, these should be given a Latin termination {Aegirtis, 

 Gdndulid). 



g. Proper names used by the ancients. Examples : Cleopatra, Belisarius, 

 Melania. 



h. Modern patronymics, to which is added an ending to denote dedication : 



a. Names terminating with a consonant take the ending ius, ia, or ium. 

 Examples : Selysius, Lamarckia, Kollikeria, Miilleria, Stalia, Kr^yeria, 

 Ibanezia.

 us, a, or um. Examples : Blainvillea, IVyvillea, Cavolinia, Fatioa, 

 Bernaya, Quoya, Schulzea. 



y. Names terminating with a take the ending ia. Example : Danaia. 



S. In generic names formed from patronymics, the particles are omitted 

 if not coalesced with the name, but the articles are retained. Examples : 

 Blainvillea, Benedenia, Chiajea, Lacepedea, Dumerilia. 



e. With patronymics consisting of two words, only one of these is used 

 in the formation of a generic name. Examples : Selysius, Targionia, 

 Edwardsia, Duthiersia. 



f. The use of proper names in the formation of compound generic names 

 is objectionable. Examples: Eugrimmia, Buchiceras, Heromorpha, Alobiusi- 

 spongia. 



i. Names of ships which should be treated the same as mythological names 

 ( Vega) or as modern patronymics. Examples : Blakea^ Hirondellea, Challengeria. 



j. Barbarous names, that is, words of nonclassic origin. Examples : Vanikoio, 

 Chilosa. Such words may receive a Latin termination. Examples : K?^m5, Fossarus.

 Clancnlus, Salifa, Torix. 



I. Names formed by anagram. Examples : Dacelo, Verlusia, Linospa. 



Art. 9. — If a genus is divided into subgenera, the name of the 

 typical subgenus must be the same as the name of the genus (see 

 Art. 25;. 



Art. 10. — When it is desired to cite the name of a subgenus, 

 this name is to be placed in parenthesis between the generic and 

 the specific names. Example : Vanessa (^Pyniineis) cardiii.
