The ventral scutes, which are much smaller, are arranged in longi- 
tudinal and transverse rows. They are strongest near the ventral middle 
and disappear towards the side. Four longitudinal rows were counted 
on one side in the scanty remains of this ossification in the present fossil. 
The length of some good specimens is from 4,5 mm. in the forward ones 
to 4 mm. in the more caudal ones and their breadth from 3,5 to 3 mm. 
Apparently the present form is not closely allied to any of the known 
exotic pseudosuchian genera. This cannot be said off-hand of the South 
African forms, because these are only known from badly preserved speci- 
mens. It will therefore be necessary to compare our form with all those 
South African reptiles which show a sufficient resemblance. 
Euparkeria Broom.— A comparison with Euparkeria shows that in 
this genus the skull is much higher with regard to the length than in our 
fossil. In other words, the skull of Euparkeria is blunt compared with 
the new form. 
The preorbital cavity in Euparkeria is much larger and has a quite 
different shape. The distance between the nostril and the preorbital 
cavity is much smaller in Euparkeria. There is further a marked difference 
in the dentition. The scapulae also show marked differences. A com- 
parison of the feet gives the same result. The first metatarsal in the foot 
of Euparkeria is slightly longer than half the third metatarsal. In the 
present form they are nearly equally long. In Euparkeria the dermal 
scutes along the back are twice as long as those of the present form. 
Mesosuchus Watson.— Although Mesosuchus is probably a Rhyn- 
chocephalian, it is not out of place to mention it here, because it was origi- 
nally taken to be a pseudosuchian. Watson, and Broom after him, both 
state that the teeth of Mesosuchus are acrodont. In the present form 
they are thecodont. The side view of the preserved part of the skull is 
quite different to that of the corresponding part of the Bloemfontein reptile. 
“ Eosuchus ” Watson. — Yon Huene pointed out that the name 
“ Eosuchus ” was preoccupied and Watson’s type will therefore have to 
be renamed. The only possible comparison with our type is with the 
metatarsals. In “ Eosuchus ” the fourth is the longest. In our form 
the third metatarsal is the longest. The foot of “ Eosuchus ” is much 
nearer to the Protorosaurus foot than that of our form. The lengths of 
metatarsals I-V in “ Eosuschus ” are : 7,5 mm., 20 mm., 27 mm., 32,5 mm., 
and 14 mm. 
Howesia Broom possesses rather Rhynchocephalian properties. 
Proterosuchus Broom is more than twice as large as our form. 
Erythrosuchus Broom is still larger. 
Apparently the above leads us to accept the present form as new and 
belonging to a new genus. I propose to call it Pedeticosaurus Leviseuri in 
honour of Mr. M. Leviseur, the enthusiastic Hon. Secretary of the Bloem- 
fontein Museum. 
Pedeticosaurus is only closely allied to one of the four known families 
of the Pseudosuchians i.e. the Ornithosuchidae. Y. Huene places Orni- 
thosuchus and Euparkeria in this family. Both these genera have broadly 
identical relations in the preorbital portion of the skull and as already 
stated above, these are entirely different to the conditions existing in
