3. “ Ornithomimus” grandis .

The type of " Ornithomimus” grandis Marsh has not been located in the United States National Museum; its generic and family reference is therefore doubtful at present. It may belong to the genus Deinodon Leidy. Hatcher’s record regarding its geological position (Bull. U. S. Geol. Surv. 257, pp. 12-41-87) is that it was found in the Eagle Sandstones.6

4 If the genus Struthiomimus is established this species should be transferred to it.
