premaxilla passes backwards to the level of the back of the canine, appearing 
in its posterior part as a narrow splint of bone lying medial to the maxilla. 
The dorsal surface has been almost completely developed. Anteriorly the 
bone forms the floor and outer side of the nasal opening — no ossified inter- 
nasal septum being present. Near the front of the nasal floor on each side 
there is a rounded foramen, and just anterior to this the septomaxilla lies 
on the premaxilla. Behind the septomaxilla the lateral portion of the 
premaxilla is a thin inclined plate of bone lying on the maxilla and passing 
back to the level of the back of the canine. Medial to this plate there is a 
deep channel which is flanked medially by an upstanding process, somewhat 
swollen above, which extends from the level of the last incisor to the level 
of the front of the canine. This palatine process forms the inner wall of 
the premaxilla and is separated from its neighbour by a deep narrow channel, 
which is partly divided by a longitudinal thin bony plate not reaching down 
to the secondary palate. This palatine process of the premaxilla does not 
seem to be separate from the main body of the bone. The bone is some- 
what cracked, and the cracks are filled with red iron oxide ; but the cracks 
are so unsymmetrical, and no one of them can be matched by a counterpart 
on the other side, that none can be considered as a suture dividing off the 
premaxilla from a prevomer. 
Broom has mentioned and figured the occurrence of such processes in 
Lycochampsa ferox and Watson in Gomphognathus polyphagus, but no 
adequate description has been given of either. 
Septomaxilla. — This bone is only preserved in the right nostril. It lies 
on the floor and against the lateral portion of the premaxilla and is almost 
completely separated by that bone from the maxilla, only meeting the latter 
at its upper corner. The front lower half of the bone is a very thin lamina, 
concave from above (called the pars horizontalis of the os narialis by Wegner, 
1922). Half-way up it thickens considerably and sends inwards a fairly 
thin turbinal process (processus intrafenestralis of Wegner) which almost 
reaches the mid-line of the skull. The turbinal process lies wholly in front 
of the palatine process of the premaxilla. On the floor of the nostril there 
is a foramen between the front of the septomaxilla and the narial portion of 
the premaxilla. The septomaxillary foramen is very small. 
Maxilla. — The maxilla carries 1 large canine and 10 molars. The molar 
series occupies a length of 103 mm. Only the sockets of the molars are 
preserved. These are longer than wide, and begin almost directly behind the 
canine. The last tooth is very small. 
Lachrymal. — This bone has contact with the prefrontal, nasal, maxilla, 
and jugal. In front of the orbit it is excavate as in many Gorgonopsids 
and is bounded behind by a pronounced ridge which forms here the antorbital 
border. At the bottom of the excavated portion is the lachrymal foramen
