lamily Endothiodoktid^:.— This family includes a number 
ot large reptiles from the Karoo formation of the Cape, of 
which the genus Endothiodon forms ilie type. They are dis- 
tinguished trom the preceding by the presence of numerous 
eeth on the palate. The skull resembles Oudenodon , but the 
muzzle is more elongated and the nares (nostrils) are terminal 
and are overhung by massive nasal bones. The border of the 
jaws has a cutting edge, but the surface of the palate and 
mandiole carry one or more longitudinal rows of columnar and 
cy indrical teeth. the palate of Endothiodon is remarkably 
mammalian in type. 
Sub-order 3.— Theriodontia.

two large foims from the Karoo beds, South Africa, namely 
Topinocephalus and Titanosuchus. Their dentition indicates a 
carnivorous type of reptiles. A n imperfect skull, several entire 
limb-bones, and vertebras are preserved in the Collection.
