DICYNODONTnLE. 19 



the ' Trans. Geol. Soc' ser. 2, vol. vii. pis. iii., iv., and also 

 in his ' Catalogue of the Fossil Eeptilia of South Africa/ 

 pi. xxiii. The tusks are considerably damaged, and the 

 borders of the orbits are broken, so that the orbital contour 

 and the width of the interorbital bar cannot be accurately 

 determined. The suture introduced into the occiput of the 

 first figure as dividing the exoccipitals from the supra- 

 occipital is really a fracture across the former. 



Presented by A. G. Bain, Esq., 1853. 



R. 859. The imperfect skull of a rather larger individual ; from the 

 Karoo system of the Gouph district near Beaufort West \ 

 south of the Nieuwveldt range. Of the cranium only the 

 preorbital portion remains, but the mandible is nearly 

 entire. The base of the tusk has the same forward incli- 

 nation as in the type. 



Pur chased from T. Bain, Esq., 1880. 



Dicynodon leoniceps, Owen 2 . 

 Syn. (?) Dicynodon recurvidens, Owen 3 . 



Of very large dimensions. Apparently allied to D. lacprtlcejps, 

 but the orbits directed mainly laterally, and not distinctly trian- 

 gular in contour ; interorbital bar very wide ; the parietal bar long 

 and narrow; and the temporal fossae also elongated and narrow. 

 The occiput seems to be inclined forwards. 



If the young skull on which D. recurvidens was founded really 

 belong to the present form there will be no question but that the 

 latter cannot be the adult of D. lacerticeps. 



Hab. South Africa. 



47047. The imperfect cranium of an adult ; from the Karoo system 

 {Fig.) of the Gat river, on the southern flank of the Sneewberg 

 range in the Graaf-Eeinet district. The type ; figured by 

 Owen in his ' Catalogue of the Fossil Eeptilia of S. Africa,' 

 pis. xxiv., xxvi. The temporal arcades have been some- 

 what crushed inwardly, but the left orbit is nearly entire. 

 The tusk approximates in its inclination to that of the 

 type, but is perhaps somewhat less oblique. The larger 

 and narrower parietal bar and temporal fossae are well 

 shown. The articular surface of the quadrate and the 

 posterior portion of the palate are well displayed. The 

 bones marked maxillae (20) in Owen's figure (pi. xxvi.) 



1 Beaufort West is on the flank of the Nieirwveldt range, and must not be 

 confounded with Fort Beaufort, which lies considerably to the eastward.
