1891] Remarks on Reptiles Called Dinosauria. 435 
those of the heavy pachydermal mammals, and attest, with 
the hollow, long bones, the terrestrial habits of the species. 
The combination of such characters, some as the sacral ones, 
altogether peculiar among reptiles, others borrowed, as it were, 
from groups now distinct from each other, and all manifested by 
creatures far surpassing in size the largest of existing reptiles, will, 
it is presumed, be deemed sufficient ground for establishing a dis- 
tinct tribe or suborder of saurian reptiles, for which I would 
propose the name of Dinosauria ” (p. 103). 
A few years later, in 1843, Fitzinger (4) placed Megalosaurus in 
the family “ Megalosauri,’ among the Loricata; Iguandon we 
find under the family name “ Therosauri,” among the order 
Sauri. ‘ 
In 1845 H. v. Meyer (5) introduced the name Pachypodes for the 
group he had established in 1830, including Iguanodon, Hylzo- 
saurus, Megalosaurus, Plateosaurus. 
Paul Gervais (6) established the families Megalosauridz and 
Iguanodontide in 1853, without giving definition. 
In 1866 Owen (7) characterized the Dinosauria thus : 
“ Cervical and anterior dorsal vertebrae with par- and diapoph- 
yses, articulating with bifurcated ribs; a few anterior vertebrz, 
more or less convex in front and cupped behind, the rest with flat 
or slightly concave articular ends; dorsal vertebrae with a neural 
platform; sacral vertebra exceeding two in number; body sup- 
ported on four strong ambulatory unguiculate limbs. Skin in 
some armed by bony scutes. Teeth confined to upper and lower 
jaws, implanted in sockets.” He names the genera: Iguanodon, 
Scelidosaurus, Megalosaurus. 
In the same year Haeckel (8) and Cope gave the first classifica- 
tion of the Dinosauria. 
Haeckel considers the Dinosauria a subclass, which he divides 
in two orders : 
“ Erste Ordnung der Dinosaurier : Harpagosauria H.; Carnivore 
Lindwiirmer. Zweite Ordnung der Dinosaurier: Therosauria H.; 
Herbivore Lindwürmer.” : 
Haeckel uses the same name as Fitzinger for the herbivorous 
forms represented by Iguanodon.
