Since 1920'S,abundant fossil mammals have been collected from the Middle Eocene Hetaoyuan Formation,Xichan,Henan Province．0n the contrary,only two reptile remains from these continental deposits have been reported——a turtle,Sinohadrianus sichuanensis Ping,1929,and a crocodile Pristichampsus aff．P．rollinati identified on the basis of several ziphodont teeth(Chowz a1．,1 973)．In recent years,with the progress of studying Eocene mammals,lower tetrapodcollections have also been accumulated．The fossils described are all dissociatedand fragmentary,and do not offer much of anatomical or phylogenetic interest；theyare sufficient in most cases,however,to identify the group to which they belong；only a few remains preserved well enough for a detailed study．Three genera oflizard and three sorts of crocodilian teeth are described in the present paper．This is the first Eocene lower tetrapod assemblage reported from China． Among them,Tinosaurus is an agamid widely distributed in the Northern Hemisphere,whileand CrPPr； henanensis are new elements ofAgamidae and Anguidae respectively．The author is deeply indebted and thankful to Tong Yongsheng for turnning these valuable materials and for allowing her to make the following description．
