OSTEOLOGY OP THE AKMOEED DINOSAUKIA. 121 As to the position of these various shaped skin scutes, the present specimen offers but few suggestions^ and anything that can be said regarding them is largely a matter of conjecture, since all were mixed up in somewhat of a disassociated manner and mingled with various other parts of the skeleton. Judging from the length of the femur the present dinosaur in life was of low stature, with a height at the hips of about 4 feet, and that it was quadrupedal in gait appears to be indicated by the robust character of such parts of the pectoral girdle and fore limbs as have been preserved. DiNosAuu Armor prom the Lance Formation. In 1911 Wieland figured' and described a number of dinosaurian dermal plates from the Lance formation of Wyoming that are now pre- served in the paleontological collections of Yale University. While none of these were so associated with other bones as to be positively identified, they are of interest as show- ing agreat diversity of shapes, and they especially emphasize the paucity of our knowledge concerning the animals to which they belong. Comply- ing with Wieland's suggestion that "it would be of very considerable interest to know the actual number and pro- portion of these elements in the collections, and especially their associations," I have prepared a brief account of those in the United States National Museum, with figures of the more characteristic plates. Cat. No. 5793 is the dermal element (fig. 73) figured by Marsh ^ as the dermal spine of Triceratops and of which Hatcher ^ says "may have been arranged in pairs ' Amer. Joum.
