Since the details of the Theromorpha-bearing beds of Sinkiang haveas yet not been fully outlined,we feel that it is too early to draw any reliablestratigraphical and pal(?)ntological conclusions now,but we mention the wealthof the fauna.The two specimens here described are all well preserved andnearly complete.According to the information supplied by Yuan,there arestill a considerable number of boxes unpacked.We hope to find more interest-ing finds so as to obtain a general view of the fauna in Sinkiang. pal(?)ntological seaking,the genera of the fauna so far recognizedare Dicynodon,Lystrosaurus and Chasmatosaurus(a Pelcosimia)(to be describedin the near future).No Cynodontia or other interesting forms are recorded.This strongly suggests that,as in the Karroo formation,Dicynodon andLystrosaurus also represent the most common and widely distributed animalsamong the other Theromorphan reptiles in Sinkiang. As far as the known forms in Sinkiang are concerned,no remarkableanatomical characters are found.All three genera are known in S.Africa.It therefore seems,that either a land connection between both existed or thatthe conditions between both during the Permo-Triassic time were extremelysimilar.
