Repoi't of the President 31 



The routine work of the department has progressed. 

 Fire-proof storage cases of superior design have been devised 

 and constructed for the skins of large mammals, and the 

 study collection has been in part rearranged. 



In addition to his department duties, the Curator has 

 continued the editorship of the Bulletm, a task which absorbs 

 more and more of his time. 



EXTINCT MAMMALS AND BIRDS 



Department of Vertebrate Paleontology. — The ac- 

 tivities of this department in the field were limited to two 

 expeditions, both of which were very successful: one to the 

 Laramie Cretaceous of Montana, under the direction of Mr. 

 Barnum Brown; the other to Wyoming for exploration of the 

 Tertiary formations of the Wind River Basin, under Mr. 

 Walter Granger. 



Among Mr. Brown's finds, especially noteworthy are a 

 nearly complete skeleton and a complete skull and jaws of 

 the gigantic horned dinosaurs or ceratopsians, and portions 

 of three skeletons of a new orthopodous dinosaur. 



After concluding the work in Montana, Mr. Brown pro- 

 ceeded to Didsbury, Alberta, Canada, and made a reconnais- 

 sance in this region, where he found abundant fossil remains 

 and a fertile field for future work. 



In Wyoming, Mr. Granger and his party explored the 

 fossil beds of the Beaver Divide, a region which apparently 

 had not previously been worked by collectors, the Lost Cabin 

 region, Muddy Creek on the Shoshone Reservation and the 

 Crowheart Butte. The material he obtained consists chiefly 

 of small mammals, and, while not of a character to make 

 showy exhibition specimens, it is especially valuable from a 

 scientific standpoint. The geologic results of this expedition 

 are especially noteworthy. 



Considerable attention has been given by Dr. Matthew to 

 perfecting the catalogue of the department material. Espe- 

 cially has he devoted his time to the preparation of a catalogue 

 of the published specimens.
