Four apparently tridactyle footprints impressed onl two coarse-grained Sandstone P!ates were collected by Mr. S. SATO'S party of geological explorers of the Mansyú Kôgyô 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 inurle Jcholosauripus s-satoi; some details are to be given in the forthcoming number of the Proceedings of the Imperial Academy, Vol.XVI.
