Abstract
Four apparently tridactyle footprints impressed on two coarse-grained sandstone plates were collected by Mr., S., SATO's party of geological explorers of the Mansyu Kogyo Kaihatu Kaisya at Ssuchiatzu near Yangshan, lying south of Choyang in Chinchou., The sandstone is presumably Cretaceous in age., The best one is here photographed (somewhat reduced, about 0., 7 of natural size)., For the convenience of future reference, the footprints are to be distinguished under the name Jeholosauripus s-satoi ; some details are to be given in the forthcoming number of the Proceedings of the Imperial Academy, Vol., XVI.,
