of the mammals. The rearrangement of the osteological 

 material has not been taken up, as was hoped would be 

 possible, owing to lack of storage facilities. 



Publications. — Eight papers published in the Bulletin for 

 this year represent the scientific work of the department. 

 Others are well advanced in preparation, including one on the 

 Muskoxen and their near allies, living and extinct, by the 

 Curator, now in press in the Memoirs. 



"A Review of the Primates," by D. G. Elliot, in three 

 royal octavo volumes, has been printed during the year, but 

 its publication has been delayed awaiting the completion of 

 the colored plates. These volumes aggregate 1,348 pages, 

 with 128 half-tone plates of skulls and figures from life, and 28 

 colored plates. This work forms the first of the Monograph 

 series, and is the largest and most important single zoological 

 publication thus far undertaken by the Museum. 



EXTINCT VERTEBRATES 



Henry Fairfield Osborn, Curator Emeritus; W. D. Matthew, Curator 



Department of Vertebrate Palaeontology. — The past 

 year has been one of unusual success in the field. In the 

 Cretaceous formations of Alberta, Associate Curator Brown 

 secured a magnificent collection of fossil reptiles including 

 three fine skulls of Horned Dinosaurs, a complete skeleton 

 with skin of a Duck-billed Dinosaur, materials for completing 

 a mounted skeleton of the great Armored Dinosaur, and a 

 large series of skulls and skeletons of dinosaurs, most of them 

 new or Httle known. Associate Curator Granger secured from 

 the Eocene of New Mexico and Wyoming a large collection of 

 the rare and interesting fossil mammals of this epoch, which 

 will be of great value in unraveling the early stages in the 

 evolution of various races of quadrupeds. Mr. Thomson 

 obtained from the Lower Miocene of Nebraska three splendidly 

 preserved skeletons of the gigantic and grotesque "Clawed 

 Ungulate " Moropus, which had been one of the greatest 

 desiderata for the Tertiary Mammal Hall. A conservative
