is the xagyugodorra of Aristotle, the Carnivora of Ray, and Fere 
of Linnzus. ‘Their claws, their abdominal mamme, and their 
organs of generation, separate the Feræ from the former 
order. 
Another natural group. is distinguished from the preceding 
under the title of ra un zagyaægoðora by Aristotle; who did not, 
however, seize its true character*. "This remained in obscurity 
until Ray described certain animals as ** Quadrupeda vivipara 
pede multifido herbivora binis prelongis dentibus anterioribus 
in utráque maxillà seu Leporinum genust.”  Linneus saw the 
truth of the order as thus characterized, from all others; but 
changed the name to Glires, which has given way among the - 
disciples of Illiger to the clumsy appellation of Prensiculantia, 
and among those of Cuvier, to the very applicable one of Ron- 
geurs or Rodentia. A Member of the Linnean Society may, 
however, be permitted to retain the name of GLIRES. 
Another most natural group was pretty well understood and 
characterized by Aristotle under the name of ra ge» ovx apdodorra, 
all other viviparous quadrupeds being appodorra,—that is, fur- 
nished with cutting-teeth or incisors in both the upper and 
under jawf. He also penei them as not furnished with 
claws: but. with- hoofs;-which-occasióned ‘Ray, who understood 
the value of the group, to call it Ungulata, all other quadrupeds 
being Unguiculata. Somehow or other, Linnzus unfortunately 
lost sight of this group, and contented himself instead with 
* Tt is not clear whether Aristotle placed this group among the au¢odovra or not. 
My only reason for thinking he did so is, that he places them in opposition to the 
xagyagotoyra. If, however, the word appo8ovra means circumdentata,—a signification 
that it will bear,—then it is clear that he could not have meant the Glires to be 
_ included in this group.
