is the xagyueodorre of Aristotle, the Carnivora of Ray, and Fere 
of Linneus. Their claws, their abdominal mamme, and their 
organs of generation, separate the Frr« from the former 
order. 
Another natural group is distinguished from the preceding 
under the title of ra wy xeeyagodovra 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 utraque maxilla seu Leporinum genust.” Linnzeus 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 Guires. 
Another most natural group was pretty well understood and 
characterized by Aristotle under the name of ra jer ovx apPodorre, 
all other viviparous quadrupeds being ePoderre,—that is, fur- 
nished with cutting-teeth or incisors in both the upper and 
under jawt. He also described them as not furnished with 
claws but with hoofs, which occasioned 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 
* It is not clear whether Aristotle placed this group among the augolovre or not. 
My only reason for thinking he did so is, that he places them in opposition to the 
xagxagodovra. If, however, the word azgodovra means circumdentata,—a signification 
that it will bear,—then it is clear that he could not haye meant the Glires to be 
included in this group.
