scribed by Cope as Episcoposaurus, because even they belong to at least 
two quite different animals. Cope describes as belonging to this species: 
“two caudal vertebre, a proximal and a distal one; one humerus; two ulne; 
a femur lacking the condyles; a proximal part of a tibia; the distal part of 
a fibula; a caleaneum and a number of dermal bones. The only part of 
the skull probably belonging to this animal is a splenial bone.” The 
named parts of the fore leg are so very much smaller than those of the 
hind leg that from all experience in Parasuchia it seems impossible that the 
animal could have been so | | 
disproportionate. The two 
caudal vertebre and the sple- 
nial (two splenials) may be- 
long to the same animal as 
the hind leg. The dermal 
bones of Mystriosuchian type 
may possibly belong to the 
latter too, but there are differ- 
ent types of scutes and it is 
hard to say whether they 
really all did belong to differ- 
ent parts of the same animal 
(species). 
In consequence I shall 
eliminate humerus, radius 
(which is also there) and 
ulna from the determination 
Episcoposaurus horridus and 
shall take the bones of the 
hind leg as the real type of 
this species, appending also 
the splenials, the two caudals. 
and possibly some of the 
scutes. 
Femur: As demonstrated 
by Cope the femur is a thick

is also the greater part of the 
distal extremity with part of the condyles of the same right femur, neglected 
by Cope (Fig. 12). And this taken together with the greater piece, though
