96 ANOMODONTIA. 



Till the form of the crowns of the incisive teeth in the Tapino- 

 cephalidce is known it is impossible to say how far the present 

 group was related to that family ; but it would seem that in this 

 group the incisive teeth were larger in proportion to the jaws than 

 in the latter. 



Genus non det. 



Indicated by two dorsal vertebrae, the centra of which are mode- 

 rately compressed, with a subtriangular cross- section and without 

 haemal carina. The transverse processes appear to have been sup- 

 ported by flange-like buttresses, and the terminal cups are of mode- 

 rate depth. 



These specimens indicate a reptile of considerably larger size than 

 the next form, but apparently allied in the structure of the vertebrae. 



Hab. South Africa. 



R. 847. Two imperfect adjacent dorsal vertebrae ; from the Karoo 

 system of the Gouph district, Beaufort West. The greater 

 portion of the neural spines are wanting. The arches are 

 fairly well preserved, and the capitular rib-facet is clearly 

 seen on the anterior border of the. upper part of the 

 centrum. The length of the centrum is 0,070 (2*75 inches) 

 and its vertical diameter 0*066 {2-6 inches). 



Purchased from T. Bain, Esq., 1880. 



Genus non det. 



Represented by a series of bones, among which the humerus agrees 

 closely in size and contour with that of Brithopus {infra), but ap- 

 parently has no ectepicondylar foramen. Vertebrae with the centra 

 much compressed and furnished with a sharp haemal carina ; the 

 centra of the dorsals being smaller and longer than those of the 

 lumbars. Transverse processes of dorsals supported by three pro- 

 minent flange-like buttresses. No intercentra in the dorsal series. 



These vertebrae closely resemble those mentioned under the head 

 of B enter osaurus. 



Hob. South Africa. 



The following associated series of specimens ivere obtained from the 

 Karoo system at Balckars Kraal, in the Bouxville district of the 

 Orange Free State, and were presented by C. S. Orpen, Esq., 1884.
