Family TAPINOCEPHALIP.E. This family includes remains of 

 two large forms from the Karoo beds, South Africa, namely, 

 Tapinocephalus and Titanosuchus. Their dentition indicates a 

 carnivorous type of reptiles. An imperfect skull, several entire 

 limb-bones, and vertebras are preserved in the Collection. 



Family GALESAURID^. Nearly the whole of the typical 

 Theriodontia are included in this family. They form a remark-

 arrangement of the teeth bearing a greater resemblance to the 

 dentition of the Mammalia than any other group of the class
