of Scymnosaiirus is unknown, bat as it is a rather highly 

 specialised type of Therocephalian, it seems likely that it is 

 fi-oni the upper division of the Lower Beaufort beds. The 

 close resemblance of Scymnosaurus to the Russian genus 

 Inostranzewia {Amalitzky) is worthy of note. They are 

 apparently distinct, but closely allied. 



I have much pleasure in naming the Natal specimen after 

 Dr. E. Warren, of the Government Museum, Pietermaritz- 

 burg. 



The specimen was discovered at the Little Tugela River 

 by Mr. P. Paterson.
