The preparietal is well developed, and the relations of the 

 bones in this region are very similar to the typical Bicynodon 

 arrangement. There is a large postfrontal.

I have much pleasure in naming the species after Dr. C. W. 

 Andrews, F.R.S., of the British Museum. 



DiCYMODON OSBORNI, sp. n. (Text-fig. 31.) 



This very strikingly new species is from Wapatsberg, near 

 New Bethesda Road, and is from beds which are undoubtedly in 

 the Lystrosaurus zone. In the same horizon are found not only 

 Lystrcsaurus, but the Therocephalian recently described by me 

 as Moschorhinus Idtchlngi. When Jloschorhimts was described 

 the exact locality was unknown to me, and when later I dis- 

 covered it I made a special expedition to the spot to try and 

 discover the back portion of the skull. Though I did not succeed 

 in getting the rest of the type, I got another imperfect skull, two 

 specimens of Lystrosaurus, and the type skull which I am now 

 describing. 



The present skull is not only of much interest as a new type, 

 but is of great importance as being one of the very iew Die ynodon
