Recommendation. — When the name of the author of a scientific name is abbrevi- 
ated, the writer will do well to conform to the list a of abbreviations published by 
the Zoological Museum of Berlin. 
Discussion. — Since authors’ names are cited as aids in bibliographic 
work, it follows that they should not be cited in a manner to render 
such work more difficult. Thus, if abbreviations are used — their use 
in connection with authors* names is not to be recommended— an 
abbreviation should be used which is not ambiguous. ‘‘Cob.,’’ for 
instance, is unfortunately used for both Cobb and Cobbold. 
Art. 23. When a species is transferred to another than the original 
genus or the specific name is combined with any other generic name 
than that with which it was originally published, the name of the 
author of the specific name is retained in the notation but placed in 
parentheses. Examples: Taenia lata Linne, 1758, and Dibothrioceph- 
alus latus (Linne, 1758); Fasciola i hepatica Linne, 1758, and Distoma 
hepaticum (Linne, 1758). 
If it is desired to cite the author of the new combination, his name 
follows the parentheses. Example: Limnatis nilotica (Savigny, 1820) 
Moquin-Tandon, 1826. 
Discussion.— If a species is transferred from one genus to another, 
the generic name is of course changed, but the old specific name, if 
valid, is retained. When Taenia lata is transferred to Dibothrioce- 
phalus , we must of course drop Taenia (for this species) in favor of 
D ibothriocephalus, but lata becomes latus. The case is very much 
like that of a woman named “ Mary Jones,*' who by marrying into the* 
Smith family becomes “Mary Smith." 
In all such transfers of species the original author responsible for 
the specific name is to be cited in parentheses. Thus u Dibothrioce- 
phalus latus (Linmeus, 1758) Liihe’, 1899," means to the zoologist that 
Linnaeus, in 1758, described a species under the name latus , - urn , 
but not as Dibothriocephalus latus / further, that Lithe quoted this 
species as Dibothriocephalus latus in 1899. 
Art. 24. When a species is divided, the restricted species to which 
the original specific name of the primitive species is attributed may 
receive a notation indicating both the name of the original author and 
the name of the reviser. Example: Taenia solium Linne, parting Goeze. 
Discussion. — As different groups of animals become better known, 
it is common experience to find that what was once considered to rep- 
resent a single species may in fact contain several distinct species. 
In separating these various forms, the original name is retained for 
one of them. Thus Taenia solium Linnseus, 1758, contained three 
species, namely, T. solium , T. saginata , and T. hydatigena (T. margi- 
nata). T. solium of to-day therefore represents only a restricted part 
of Taenia solium as known to Linnaeus, 1758.
