tamaricinus, ineridianus LinGmel.”; the author quotes “ Gerbidlus Desm.” as 
a synonym; the diagnosis of the genus is not applicable to Zapus; and, as 
if to clinch the matter, Illiger expressly enumerates ‘‘ Dipus canadensis Shaw” 
under a preceding genus, Dipus. Hence it is clear that Meriones, as proposed 
by Illiger, had no reference, even by implication, to the American type Zapus. 
But, a few years afterward, in 1825, Fréd. Cuvier (Dents des Mammif. ete. 
p. 187) committed the Gallicism of Meriones, and said: “Le type de ce genre 
est le dipus americanus, de Barton,” without the slightest allusion to Iliger,— 
just as if he were proposing a new genus. All that he did, however, was 
to transfer Illiger’s name to a totally different generic type, to which Illiger 
never intended it to apply. The case is parallel with that of Wagler’s and 
Wagner's transferring of Jacudus from certain Old World types to the Ameri- 
can one. It is immaterial whether or not Meriones is tenable for the group 
upon which Illiger based it; it certainly cannot stand for any other group. 
Hence it is clear that the Aierican animal never had a name based upon 
itself, nor any tenable name, until Zapus was proposed. In establishing the 
genus, I thought it unnecessary to more than briefly allude to the facts in the 
case; but, as { observe some indisposition to coincide in this instance with 
my views, I have thought proper to set forth my reasons at length.
