Tkeriodontia Clepsydrop id&. 



Two very remarkable genera of Theriodonts, Cynognathus and 

 Gomphognathus, have lately been described by Prof. H. G. 

 Seeley. In both the skull is remarkable for its mammalian 

 appearance, that of Cynognathus especially, with its small^'incisors 

 and powerful canines, having a striking resemblance to the 

 skull of a Carnivore, such as the wolf. The occipital condyle 

 is double, also a mammalian character, and the quadrate is 

 much reduced, ^n imperfect skeleton of Cynognathus crater- 

 onotus is exhibited in a separate case in the middle of the gallery. 

 Gomphognathus is further remarkable for its broad-crowned 

 molar teeth.

Naosaurus. Family CLEPSYDROPID^:. These Theriodonts differ from the 



GALESAURID^; either in having teeth on the palate, or by the 

 extraordinary character of their dorsal vertebrae, in which large 

 intercentra are typically present. These forms all belong to
