32 AN0M0D0NTIA. 



R. 1720. The frontal region of a somewhat larger cranium appa- 

 rently referable to this species ; from the Karoo system of 

 the Cape Colony. This specimen exhibits very clearly the 

 marked eversion of the anterior border of the orbit and 

 the prominent tuberosity above the nares, which form 

 such striking features in the type skull. 



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



36252. The imperfect cranium of an adult individual; from the 

 (Fig.) Beaufort beds of the Karoo system on the Brak river, near 

 Fort Beaufort. The type of U. magnus ; figured by Owen 

 in his ' Catalogue/ pis. liv., lv., lvi. This specimen agrees 

 so exactly in contour with the preceding that there is no 

 reasonable doubt as to their specific identity. The parietal 

 bar in the present specimen is indeed constricted into a 

 sagittal crest ; but this appears to be due solely to age. 



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



38237. The symphysial extremity of the mandible, associated with 

 (Fig.) the preceding. Figured by Owen, op. cit. pi. lvii. The 



extremity of the beak has been cut and polished to show 



the absence of teeth. 



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



Udenodon greyi, Owen *. 



Known by a small and probably immature skull. Distinguished 

 from the young of U. prognathus by the narrower parietal and inter- 

 orbital bars. 



Hab. South Africa. 



36231. The imperfect and laterally crushed skull, showing on the 

 (Fig.) left side several of the hyoid bones ; from the Beaufort 

 beds of the Karoo system of the Rhenosterberg branch of 

 the Sneewberg range 2 . The type ; figured by Owen in 

 the ' Quart. Journ. Geol. Soc' vol. xvi. pi. iii. fig. 5, and 

 also in his ' Catalogue of the Fossil Reptilia of S. Africa,' 

 pi. lxii., and pi. lxv. fig. 8. 



Presented by Sir George Grey, K.C.B., 1858.
