SOME CARNIVOROUS THERAPSIDS. 1023 
bounded on the outside by a narrow bar which is certainly trans- 
palatine. The pterygoid no doubt combines with this bone to 
form the relatively small flange against the inner side of the lower 
jaw. Behind this region the two bones are separated by a small 
interpterygoid vacuity, which is shown quite conclusively to be 
undivided, no parasphenoid crossing it as is usually the case in 
early Therapsids. 
The inner edge of the pterygoid, which forms the border of 
this vacuity, rises, when viewed from below, until it meets its 
fellow, and the two then end in suture with the very deep keel of 
the basisphenoid. 
From the pterygoid at the side of the interpterygoid vacuity 
the posterior ramus runs off. It has a deep flange down its outer 
border and a horizontal ledge on the inner side. The pterygoid 
ramus of the quadrate runs along the front face of this bone as in 
all reptiles, whilst in the Cynognathids, in which the apparent 
posterior ramus of the pterygoid is really formed by the alisphe- 
noid (=epipterygoid), it runs behind. 
With the skull of Bauria described above are some very badly 
preserved posteranial bones. The scapula is fairly well preserved, 
and seems to show that the blade was narrow and had no spine 
and no definite acromion. 
The coracoid and precoracoid are also shown; they are of the 
ordinary South-African Therapsid type, but are relatively very 
large. The whole arrangement must have closely resembled that 
figured by Dr. Broom in /etidosaurus. 
MiICROGOMPHODON OLIGocyNus Seeley. (Text-fig. 2.) 
Another Cynodont which must be regarded as a close ally of 
Bauria is Microgomphodon oligocynus, known only by the type- 
skull. [The fine skeletal fragment which Seeley referred to this 
-genus is shown by the very unsatisfactory jaw fragment to he 
quite distinct, being, no doubt, a Cynognathid. | 
ape type-skull is illustrated with slight restoration in text- 
fig. which should be compared with Prof. Seeley’s excellent 
Tcheewenie figures (Phil. Trans. 1895, B, pl. i. figs. 1-4). The 
animal resembles Bawria in the following respects :— 
The short temporal region. 
The relatively heavy face. 
The dentition. 
The presence of an interpterygoid vacuity. 
The presence of suborbital vacuities. 
The slight reduction of the posterior part of the lower 
jaw. 
7. Small squamosal, 
8. The nostril directed more anteriorly than outward. 
9. The nasal not widened. posteriorly. 
10. The frontal entering into the orbital margin.
