by the Canadian (jeological Survey. He likewise continued work in 

 joint authorship with Dr. Ferdinand Canu, of Versailles, France, 

 on a monograph of American Tertiary Bryozoa, which at the end 

 of the year had grown to such proportions that it became necessary 

 to subdivide it. The first volume, which will deal with the early 

 Tertiary Bryozoa, will be published by the United States Geological 

 Survey. 



Y ertebrate pcdeontology. — Especially noteworthy among the ac- 

 cessions to this section were some 600 separate bones of vertebrates 

 from the Blackfeet Indian Reservation in northwestern Montana, 

 collected by Mr. Charles W. Gilmore, assistant curator, while on de- 

 tail with the Geological Survey, by which they were transferred to 

 the Museum. Aside from filling important gaps in the reptilian 

 series, this material furnished the type of a new species, Brachy- 

 ceratops montanensis Gilmore, as well as an exceptional specimen for 

 exhibition. Also of much importance are several hundred specimens 

 obtained by Mr. James W. Gidley, assistant curator, in the course of 

 further explorations of the cave deposit near Cumberland, Md., 

 begun the previous year. They include many nearly complete skulls, 

 jaws, and articulate feet and limbs, belonging in part to genera and 

 species not previously reported from the locality. A mountable 

 skeleton and several good skulls of a new genus of peccary are not- 

 able; and bears, small carnivores, rodents, etc., are well represented. 



Collections made by Mr. William Palmer and Mr. Norman H. 

 Boss, of the Museum staff, in Miocene deposits near Chesapeake 

 Beach, Md., contain a nearly complete skeleton, with skull and jaws, 

 and a second nearly perfect skull of fossil porpoises, both suitable for 

 exhibition purposes, besides several more or less fragmental parts 

 of porpoises and other cetaceans. A small beak secured by Mr. Boss 

 is of particular interest on account of the perfect preservation of the 

 jaws and teeth. A skull, lower jaw, and five cervical vertebrae of the 

 fossil bison. Bison alleni, from Alaska, a fine exhibition specimen, 

 was obtained by purchase from Dr. O. P. Hay; and the type speci- 

 men of Crossotelos annulatus Case was received in exchange from 

 Dr. E. C. Case, of the University of Michigan. Valuable material 

 was also contained in 10 other small accessions. 



Some 66 boxes of the " Marsh collection " were opened and their 

 contents worked out. Much other material from the Geological Sur- 

 vey, resulting from more recent field work, was also made ready for 

 study. The most important progress on the reptile collection com- 

 prised the mounting of the nearly complete skeleton of the new 

 dinosaur, These elosaurus neglectus^ and of a partial skeleton of the 

 duck-billed form, Trachodon; the practical completion of the work 

 of cleaning up the Stegosaunts material; the preparation of partial 

 skeletons of five individuals of the Ceratopsian dinosaur Brachy-
