Amherst College and Mr. Brooks, a recent graduate of Amherst. 

 They were successful in discovering a skull which lacked the upper 

 portions of the horns only, and which has an especially complete 

 frill. Portions of the skeleton also of the same animal and of 

 other homed Dinosaurs and the remains of a carnivorous 

 Dinosaur of gigantic size were found; and just before the 

 expedition closed three Crocodile skeletons and portions of the 

 skeletons of several beaked Lizards (rhynchocephalians) were 

 discovered. 



The second expedition in Montana, under the leadership of 

 Dr. W. D. Matthew, was in quest of mammals, chiefly of the Mio- 

 cene period. Two important discoveries were made. First, of 

 the beds containing the remains of some of the smaller animals 

 of the period when the Titanotheres flourished, especially small 

 carnivores and rodents and some primitive species of Horse, 

 among them Mesohippus westoni. The small fauna of the lower 

 Oligocene had already been made known partly through the re- 

 searches of Earl Douglas, but our collection greatly adds to his 

 interesting results. The second discovery of this party consisted 

 of the lower jaws and extensive portions of the limbs and skele- 

 ton of a large Rhinoceros, probably belonging to the species R. 

 lualacorhinus Cope, a long-limbed animal which has been known 

 hitherto from its skull and a single foot bone only. We are 

 now enabled to give almost the complete characters of this long- 

 limbed and long-skulled type, which stands in marked contrast 

 to the more abundant short-limbed and short-skulled Rhinoceros 

 of the same period, named Teleoceras. 



The third expedition, under the leadershi]) of Walter Granger 

 asstjciated with Peter Kaison, returned to the vicinity of the fa- 

 mous Bone CaVjin dinosaur quarry of central Wyoming for the 

 fourth year of excavation. The early part of the season was de- 

 voted to a new dinosaur quarry discovered by W. H. Reed, and 

 systematically explored by the Museum for the first time in 1901. 

 This quarry proved to be very rich, especially in remains of the 

 giant herbivorous Dinosaur named Camarasanrns. After work was 

 finished at this point, the Bone Cabin quarry was systematically
