to its original contour it would appear that the mandible was com- 

 paratively narrow and pointed at the symphysis, and the cranium 

 somewhat less depressed, and with a deeper postorbital flange than 

 in the next species.

R. 1710. Fragment of the right mandibular ramus ; from the 

 {Fig.) Beaufort beds of the Karoo -system on Ihe Blinkwater 

 river, south of the Winterberg peak l , north of Fort 

 Beaufort. This specimen, which appears to be all that 

 now remains of the type skull, has been vertically cut and 

 polished, and exhibits three teeth in use, and a germ- 

 tooth in its alveolus. Described and figured by Owen in 

 his ' Catalogue of the Fossil Eeptilia of S. Africa/ p. 8, 

 no. 15, pi. viii. figs. 1, 2, and also by Seeley in the * Phil. 

 Trans.' for 1888, p. 74, pi. xvi. fig. 2.

R. 1710 a. Cast of the imperfect and distorted skull. The original, 



(Fig.) of which the preceding specimen is a fragment, was the 



type. The cast is figured by Owen in his i Catalogue/ 



pis. vi., vii., and also (from the palatal aspect) by Seeley 



in the ' Phil. Trans/ for 1888, pi. xvi. fig. 1.

Pariasaurus bombidens, Owen 2 . 



This species was originally said to differ from the type by the 

 teeth having broader serrations, and a more convex contour of the 

 outer surface, but subsequent observations throw doubt on the 

 validity of these differences 3 . It is suggested 4 that the cranium 

 was more depressed than in the type, with a deeper postorbital 

 flange, and a wider and more rounded mandible. It is, however, 

 difficult to say whether the latter differences are not at least par- 

 tially due to the crushed and imperfect condition of the type skull. 

 The length of the entire skeleton is approximately about 8 feet. 

 The ilium has a prominence in advance of the acetabulum.
