4. Both the preceeding article and article 21 of the rules 
adopted by the Zoological Congress of Paris, in 1889, are ap- 
plicable to names of persons, as Boydanovi, Metcknikovi. 
5. The virginal spelling and all diacritic signs must be pre- 
served in the Roumanian and certain other Slavonic languages 
(Polish, Croatien, Bohemian), and likewise in those which use 
the Latin alphabet, as Tania Medici, Congeria CZjzzki. 
6. Specific names may be formed from feminine patrony- 
mics or from common nouns. In such cases the genitive takes 
the ending oe or orum to the full name of the person to whom

(b) A capital letter can be used with certain geographical 
names, as Antillarum, Galliae. 
(c) In all other cases, the specific name is spelled with a 
small letter, as Oestrus bovis, Corvus corax, Inula helenium. 
8. If the name of the subgenus is cited, it should be placed 
in parenthesis between the generic and specific names, as 
Hirudo (Haemopis) sanguisuga. 
9. If the name of a subspecies or variety is cited, it follows 
the specific name without any inter-punctuation. The name 
of the author of this subspecies or variety can be cited likewise 
without inter-punctuation, as Rana esculenta marmorata Hallo- 
well. 
10. If a species has been placed in a genus other than the 
one to which it was assigned by its author, the name of this 
author is retained in notation, but placed in parenthesis, as 
Pontobdella muricata (Linné). 
V. SUBDIVISION AND CONSOLIDATION OF GENERA AND
