No. 1. A fairly complete skull, with lower jaw, of an animal 

 slightly smallei" than the type. A consi(lera])le part of the 

 premaxillarj' is woathert^d away, but the other bones of the top of 

 the head are well shown. The nasals forma median suture of 

 nearly an inch, behind the upper end of the median process of 

 the premaxillary. Behind the frontals and the front of the 

 parietal foramen is the median preparietal. Between the frontals 

 and the bones which have usually been regarded as postfrontals 

 are interposed a very distinct pair of narrow^ bones. These are 

 very similar to those figured by Seeley in the skull of 

 Morhlorhinus ,>//tfi/>r/)s (Ann. and Mag. Nat. Hist., Feb. 1808), 

 and regarded by him as postorbitals. But as it has been custo- 

 mary to regard the anterior and upper of the two bones behind 

 the orbit, as the postfrontal and the posterior, the postorbital, we 

 must look upon the narrow bone as the true postfrontal — 

 apparently lost in the other Dicynodonts— and the large bone 

 which has hitherto l^een looked upon as the postfrontal as really 

 the postorbital. The specimen has been split transversely, and 

 there has been revealed much of the internal structure of the 

 skull. The parietals are seen to form lateral walls to the brain 

 cavity, and in front they are seen articulating with the 

 columella. A section of the true vomer is seen with the palatine 

 on either side, and in contact posteriorly with the large median 

 sphenoid. In the mandible the dentary is much exfoliated 

 but the surangular and angular are well shown with between them 

 and the dentary a large oval foramen. The angular has a large 

 downward and inward process, as in Udenodon. The articular 

 is a fairly large element.

No. 2. A badly weathered skull, which has lost the front of 

 the snout, and practically all the bones of the frontal, parietal and 

 occipital regions. It has been split transversely in the plane of the 

 pterygoids, and the larger fragment again vertically near the 

 middle line. Tlie first fracture shows thoroughly the structure of
