TAPINOCEPHAXID.E. 81 



incisives are shown. The latter have very small pulp- 

 cavities, and are thereby readily distinguished from the 

 corresponding teeth of the following family. 



Presented by the Director of the Albany Museum. 



Gexerically Fndetekjilned Specimens. 



R. 1722. The proximal half of the right humerus of a large form ; 

 from the Karoo system of the Cape Colony. This spe- 

 cimen is broken off at the entepicondylar foramen. 

 Although of smaller size, it approximates in contour to 

 the humerus of Cynodraco. 



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



36300. The distal portion of a right humerus, agreeing in size with 

 the preceding specimen, and probably referable to the 

 present suborder ; from the Karoo system of the Rhen- 

 osterberg branch of the Sneewberg range. 



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



R. 510. Fragment of rock containing numerous imperfect bones of 

 a small Anomodont probably referable to the present 

 suborder ; from the Karoo system of the Orange Free State. 

 This specimen shows a portion of the dorso-lumbar and 

 caudal regions of the vertebral column, portions of the 

 pelvis, the femur of either side, and the left tibia. 



By exchange with the Blomfontein Museum. 



Family TAPINOCEPHALID.F1. 



This family is taken to include the undermentioned imperfectly 

 known large forms. The teeth always appear to have had large 

 pulp-cavities, but in the type genus the nature of the dentition is 

 very imperfectly known, although there were apparently no tusk- 

 like teeth. In the other genus, however, the dentition was of a 

 carnivorous type and differentiated into groups. The type genus 

 appears to have no secondary posterior nares. 



Vertebra? notochordal, with flattened terminal faces to the centra 

 and moderately tall neural spines; no intercentra in dorsal region. 

 Humerus relatively short and wide, with the proximal extremity 

 much expauded, and a sudden angulation at the point of origin of 

 the dclto-pectoral crest.
