Report of the President. 27 



Although the expeditions were planned to secure fossil 

 horses, incidentally several splendid specimens of other 

 animals were discovered. Among them was the shell of 

 a great Glyptodont, or armored Edentate, the first discovered 

 in North America. Numerous remains of Camels, Rhin- 

 oceroses and the skull and skeleton of the great fossil Dog, 

 Dinocyon, were also found. 



The exploration for Dinosaurs, begun by the Museum in 

 1897, was continued in western Colorado, in the Black Hills 

 region of South Dakota and in the Laramie Plains of central 

 Wyoming. At the last point, the Bone Cabin Quarry, famous 

 for the great discoveries that have been made there, was 

 worked for a fourth season, yielding a number of very rare 

 Dinosaur skulls more or less complete. In this same region 

 another quarry, together with a quantity of very large Dinosaur 

 bones, was purchased. ' The car-load of material thus obtained 

 was loaded and transported directly to the East through 

 the courtesy of Messrs. E. H. Harriman and J. P. Morgan. 



The department has been enriched not only by the expedi- 

 tions, but also by exchanges with foreign museums. Chief 

 among these is the superb specimen of an Ichthyosaur, or 

 Fish-lizard, presented by the Royal Museum of Stuttgart 

 through Prof. Eberhard Fraas. It is remarkable as contain- 

 ing seven young Ichthyosaurs. Two noteworthy purchases 

 have been made: The first, a magnificent Cretaceous fish 

 belonging to the genus Porthens, allied to Chirocentrus, now 

 found only in the Indian Ocean; and the second, a skull of a 

 southern variety of the mammoth, Elephas imperator, with a 

 pair of large tusks more than thirteen feet in length. 



Reproductions of restorations made in the department have 

 been sent to museums in various parts of the world, and new 

 series of casts have been prepared. Among these the casts 

 illustrating the evolution of the feet of the Horse and the 

 Camel are of special note. 



The scientific work of the Department has continued, sev- 

 eral bulletins by the Curator and his associates and a valuable 

 memoir on the fossil mammals of eastern Colorado having 

 been published.
