1891.] Remarks on Reptiles Called Dinosauria. 441 
“Feet ungulate; pubis projecting and connected 
in front; no postpubis. Opisthoceha. 
Feet ungulate; pubes projecting free in front ; 
postpubis present. Orthopoda. 
Feet unguiculate; pubes projecting downwards 
and coossified distally ; calcaneum not pro- 
duced. Gontopoda. 
Feet unguiculate; calcaneum much produced 
backwards; (?) pelvis. Hallopoda.” 
In 1884 Marsh (20) again published another classification. He 
divided the sub-class Dinosauria into four orders and three sub- 
orders : 
1. Order Sauropoda. 
2. “ Stegosauria. 
3. “Ornithopoda. 
4. “ Theropoda: 
Suborder Cceluria. 
“ — Compsognatha. 
“ Ceratosauria. 
The Hallopoda are now considered an soli of atic not 
placed within the Dinosaurs. 
In 1885 Cope (21) placed the Criscia among the Dinosauria, 
and gave the following character: “Os quadratum immovably 
articulated, capitular and tubercular rib articulations distinct. 
Ischium and pubis distinct, the latter directed forwards, back- ` 
wards, or downwards ; two posterior cranial arches; limbs ambu- 
latory ; no procoracoid.” 
In 1887 (22) Baur divided the Dinosauria in three groups: 
“ A. Carnivorous Dinosaurs, Harpagosauria Haeckel, 1866. 
I. Goniopoda Cope, 1886 (Theropoda Marsh, 1881). 
B. Herbivorous Dinosaurs, Therosauria Haeckel, 1866. 
II. Orthopoda Cope, 1866. 
1. Ornithopoda Marsh, 1881. 
2. Stegosauria Marsh, 1877. 
C. Crocodilian-like Dinosaurs, Sauropoda Marsh, 1878. 
III. Opisthoccelia Owen, 1859.” 
In the same year Prof. Seeley (23) gave a new classification.
