34 Mr. W.S. Macueay on the Comparative Anatomy 
unt.” p.83. Hermann finally gave it the generi¢ name of Hy- 
rav, which Illiger adopting, placed the animal itself in his Pro- 
dromus, p. 95, as the link between the Cavies and the Bruta of 
Linneus. In the Régne Animal, we discover this puzzling genus 
forming together with the Rhinoceros one small group of the 
Ungulata, with the observation that, ‘en les examinant bien 
on trouve qu’a la corne prés ce sont en quelque sorte de Rhino- 
ceros en miniature.” (vol. i. p. 240.) Hence it is allowable, I 
conceive, to pass from the Glires to the Ungulata. 
When Dampier and Ray assigned the name of Sea Cow to 
the Manati of the West Indies, they probably gave the hint of 
that anatomical affinity to Ungulata, which has been followed up 
and proved by subsequent zoologists, Accordingly, Linnzus 
went so far as to place the Manati among his Bruta. And 
M. de Blainville, trusting entirely to the principle of division, 
and ignorant of the maxim of variation, has said* that, ‘le 
Lamantin appartient au groupe qui contient les Elephans dont 
il n’est qu'une modification propre 4 vivre dans l’eau.” Now, 
though it is difficult to look at a Manati or Dugong, and call it 
an Elephant, it is impossible to deny that it is a modification of 
the Pachyderm form ; and therefore we cannot refuse our assent 
to the accuracy of M. Cuvier in making the Herbivorous Ce- 
tacea follow the Ungulata in the arrangement of the Reégne 
Animal. 
Arrived thus, then, among those enormous Mammalia, which 
Nature points out to us as the direct medium of her transition 
from the Quadruped form to that of Fish, we proceed in the 
series of Mammalia to the genera Trichecus and Phoca. It is 
true indeed, that M. Cuvier, from the artificial plan of the 
Regne Animal, is obliged to deny this affinity, or at least to 
make no mention of it in the work: but it has been noticed
