of certain Birds of Cuba. 29 
also the most remarkable instances of the upper and under man- 
dibles touching each other merely at their base and point; as 
Myrmecophaga, or the whole of the ra wev ove audodovra of Ari- 
stotle, and Anastomus* Illig. Both orders exhibit ornamental 
appendages to the head,—as the antlers of the Stag and the crown 
of the Crane ; and both afford us the only instances of true horns, 
—as Bos or Rhinoceros, and Palamedea L. To see a hundred 
such instances of resemblance it is only necessary to walk into a 
museum. I shall therefore only further say, that both orders 
contain polygamous animals, are generally gregarious, and more 
graminivorous than granivorous, being essentially inhabitants 
of marshes and savannahs. Thus then, with Linneus, I place 
the Bruta, or rather the whole order of Ungulata to which they 
belong, opposite to the Grallatores. 
Four orders in each class being now disposed of, it follows by 
parallelism of analogy, that the Glires ought to be placed oppo- 
site to the Rasores. But setting theory wholly aside,—is this 
position true in factt? 
Linneus, from the above-mentioned error in his series of 
affinity, considered the Rasores to be analogous to his group of 
Pecora. But this group, according to Aristotle and Ray, is 
only a subdivision of Ungulata, which have, I consider, been 
now proved to be analogous to the Grallatores. If, therefore, 
Linneus be right in making his Bruta analogous to the order of 
Wading Birds, it follows that his Pecora must be so also. 
* The genus Aramus, which I have killed in this island, also presents the peculiarity 
of the mandibles not meeting towards the middle of the beak. 
+ The ancient name of Strudhio Camelus, as well as the form and habits of the 
Ostrich, show indeed a relation of analogy to the Camel; but then we are to recollect, 
in the first place, that the Ostrich is at the osculant point or confines of the orders of 
Gralle and Rasores; and secondly, that such slight variations of the parallelism of 
analogy often appear, although, as has been said, Hore Entom. p. 403, I think it pos- 
sible that even these are subject to rule.
