degree of sub-species or a sub-species becomes a 

 species. 



st 25. — The name of the typical sub-genus 

 should be the same as that of the genus. 



Clause 26. — When a species has been finallv 

 placed in a genus other than that in which its 

 author placed it. the name of this author is pre- 

 served in the notation, but placed in parenthesis, 

 with the date at which the species has been 

 established. Ex., Pontobdella muricata iLinne), or 

 delta muricata (Linne, 175S). 



The name of the author who has transferred a 

 species into another genus can be placed after the 

 name of the author of the species, but outside the 

 parenthesis. Ex., Pontobdella muricata (Linne) 

 Lamarck, or Pontobdella muricata (Linne, 175S), 

 Lamarck. 1S1S 



--. — When a species is divided, the 

 species to which is given the name of the primitive 

 species can have a notation showing at the same 

 time the name of the author who established the 

 original species and of he who made the sub- 

 division of this species. Ex., Taenia solium Linne 

 partim Kuchenmeister. 



In conformity with Clause 26, the name of the 

 first author is put in parenthesis if the species has 

 been transferred into another genus. 



Clause 2->. — A genus formed by the union of 

 several others takes the name of the oldest of the 

 genera or sub-genera which compose it. 



If the names are of the same date, that which 

 has been chosen by the first reviser should remain. 



Clause 29 — The above rule is applicable when 

 several species or sub-species are united into one. 



Clause 30. — If, on the joining together of two 

 genera, two animals having the same specific name 

 are in the new genus, the more recent should lose 

 its specific name and receive a new one.

Clause 31.— Family names are formed by adding 

 the termination idae to the root of the genus which 

 is the type Subdivisions of the family are 

 designated by adding the termination inac to the 

 name of the genus which is the type 



Clau-.e 32 — The family name should disappear 

 and be replaced if the generic name on which it is 

 flooded falls away in the synonym and dis.i;

(b) That the author has understood and applied 

 the rules of binomial nomenclature. 



Clause 34. — The tenth edition of the " Systema 

 Naturae" (175S) is the work to be followed in the 

 general application of the binomial system in 

 zoological nomenclature. The date 1758 is, 

 therefore, accepted as the starting-point of 

 zoological nomenclature and the appearance of 

 the law of priority. 



Clause 35. — The law of priority prevails, and 

 consequently the oldest name is the one pre- 

 served : 



(a) When any part of an animal has been named 

 before the animal itself ; 



(b) When a larva has been named before the 

 imago. 



Exception is made, at least for the present, for 

 animals in metamorphosis or migration ; many of 

 which species ought to be subjected to a revision, 

 which would result in a considerable overthrow- of 

 the nomenclature : 



(c) When two sexes of the same species have 

 been considered as distinct species, or even as 

 belonging to distinct genera ; 



(d) When the animal has a regular succession of 

 different generations which have been con- 

 sidered as belonging to distinct species or 

 genera. 



Clause 36. — When several names have been 

 proposed simultaneously, without it being possible 

 to establish the priority, the name to be adopted 

 is : 



(«) The name by which a typical species is 

 designated, if it is not already the name of a 

 genus ; 

 (&) The name which is accompanied by a draw- 

 ing, a diagnosis, or a description of an adult, if 

 it is not already the name of a species; 



(c) The name chosen by the author of the first 

 revision ; 



(d) All things being equal, the name cited in the 

 first place in the work. 



Clause 37. — All generic names already in use in 

 zoology are rejected. 



Clause 38.— In the same way all specific names 

 already in use in a genus are rejected. 



Clause 39.— Names rejected because of homonymy 

 cannot be used again. Names rejected in con- 

 sequence of synonymy cannot be again employed, 

 In the case of the restoration of groups 

 suppressed by mistake. 



1 -A generic or specific name once made 

 public cannot be rejected for an improper reason, 

 even by its author.
