from one anotlier, but it is quite manifest tliat the lachrymal 

 is small and the pi'efrontal only moderate-sized. The na.sal 

 extends well back and forms a broad suture with the frontal. 

 The frontals form the greater part of the interorbital region 

 and most of the supraorbital ridge. There are no postfrontals, 

 and the postorbitals are remarkable in forming only a postorbital 

 process and in not meeting the jngal to form a postorbital arch. 

 The jugal is slender and passes back nearly to the articular region. 

 The portion of the squamosal that supports the quadrate is well 

 developed, but the zygomatic portion is slender.

Side view of the type and only known specimen of JBaiiria cynofs. Since the speci- 

 men w.as first figured it has been considerably further developed at the British 

 Museum and by myself. The jaws are represented as closed. The molar teeth 

 must meet one another as shown in the figure. When first described the teeth 

 were regarded as round, but further development shows that thej' are about 

 twice as broad in one diameter as in the other. Though the incisors are mostly 

 broken the impressions of the gi'eater part of each is preserved, and the lower 

 must have met the upper as shown in the figure. The jugal arch is represented 

 in its central part only by the impression, but there is no doubt it must have 

 been practically as restored. It certainly did not meet the postorbital, which 

 is perfectly preserved on both sides. All the sutures shown in unbroken line 

 can be clearly made out. 



The palate is as in typical Cynodonts, the secondary palate 

 being as well developed. The vomer, palatines, and pterygoid, so 

 far as can be seen, all are of the ordinary Cynodont type. The 

 lower part of the alisphenoid appears to be of the same type as in 

 higher Cynodonts, articulating with the basisphenoid and passing 

 out to the quadrate. It is just possible, however, that this 

 outward extension may be, as in the Therocephalians, entirely 

 formed by the pterygoid. The basisphenoid is unlike that of 

 either the Anomodonts, Therocephalians, or higher Cynodonts. 

 It is short, with a broad articulation for the basioccipital behind, 

 and a narrow articulation in front for the alisphenoid and 

 probably the vomer. From its under surface there passes down
