30 INDEX GENERUM MAMMALIUM. 
of gerbilles (Gerbillinze) of northeast Africa. The same name was pro- 
posed by Le Conte in 1830 for a group of meadow mice (Microtinz) 
from Georgia, and by Peeppig in 1835 for a group of octodonts (Octo- 
dontinz) from Chile. Both Le Conte and Peppig were evidently 
ignorant of the previous use of Psammomys at the time their descrip- 
tions were published. | Orca was applied by Wagler in 1830 to a group 
of toothed whales, including De/phinus bidentatus and D. desmaresti, 
while 7irs/o was used by him for Delphinus peronii from the southern 
seas. Gray in 1846 adopted De/phinapterus for the latter species and 
transferred the name 7^s;o to another group of dolphins typified by 
Delphinus tursio from the North Atlantic and North Sea. In both 
these cases the names used by the later authors are homonyms, pro- 
posed inadvertently in the case of Psammomys and intentionally in the 
case of Zurs/o. ‘The extent to which such homonyms have been pub 
lished has not been generally appreciated. About 150 useless names 
are attributable to this source alone, and most of them would not 
have been published if their authors had used more care or had had 
access to a fairly complete list of the genera of mammals already pro- 
posed. A full list of the duplicated names is given below, and one of 
the objects of this index will have been attained if such duplication 
of mammal names is avoided in future.
