REPORT OF NATIONAL MUSEUM, 1914. 1238 
by the Canadian Geological 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. 
Vertebrate paleontology.—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 vertebrze 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, Vhescelosaurus neglectus, and of a partial skeleton of the 
duck-billed form, Z’rachodon, the practical completion of the work 
of cleaning up the Stegosaurus material; the preparation of partial 
skeletons of five individuals of the Ceratopsian dinosaur Brachy-
