DICYNODONTID^. 23 



of this specimen resembles that of the type, although the 

 parietal bar is relatively wider. The parietal foramen is 

 very large, and although proportionately much smaller in 

 the type is still comparatively large.

** Dicynodon rectidens, Owen 1 . 



A doubtful species, apparently only separable from the preceding 

 by the cylindrical section of the tusk. 

 Hob. South Africa. 



47057. The imperfect skull ; from the Beaufort beds of the Karoo 

 {Fig.) system near Fort Beaufort. The type specimen ; figured 



by Owen in his ' Catalogue of the Fossil Reptilia of 

 S. Africa,' pi. xl. The whole of the upper surface of the 

 cranium is wanting. If placed in the same position as 

 the type skull of D. pardiceps (which is not the case in 

 the figures), the contour of the two appears to be identical. 

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



47058. Mass of rock containing five imperfect dorsal vertebrae 

 (Fig.) apparently associated with the pieceding specimen. 



Figured by Owen in his ' Catalogue,' pi. xxxv. fig. 3. 

 Two of the vertebral centra have been longitudinally 

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



47058 a. Mass of rock containing some imperfect cervical (?) ver- 

 tebrae and some flat bones, probably belonging to the same 

 individual as the preceding specimen. 



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



** Dicynodon curvatns, Owen 2 . 



Founded upon a very imperfect cranium which appears to ap- 

 proximate in contour to that of D. pardiceps. 



Hob. South Africa. 

 R. 1655. Cast of the imperfect cranium. The original, which is the 

 type, and was formerly in the collection of the late Prof. 

 John Morris, was obtained from the Beaufort beds of the 

 Karoo system at Cradock 3 , on the upper part of the Great 

 Fish river, north-west of Fort Beaufort.
