54 REPORT OF NATIONAL MUSEUM, 1908. 
Gustav Hambach collection included a number of fossil fishes, rep- 
tiles, and mammals. The collection obtained by Mr. C. W. Gilmore 
on the Smithsonian expedition to Alaska during the summer of 
1907 and deposited in the Museum contains several fragmentary 
specimens representing fossil species of the mastodon, bison, musk ox, 
caribou, beaver, ete. The most important find was a nearly complete 
skull of a new species of Ovébos, which Mr. Gidley has described 
under the name Ov/hos yuhonensis. A fossil turtle from the Kansas 
chalk is also worthy of mention. 
The Teleoceras remains, so extensively represented in the Marsh 
collection, have been completely overhauled and cleaned, and from 
them has been selected sufficient material for the purposes of the Na- 
tional Museum, together with a fine lot of duplicates for exchange. 
This work was greatly delayed by Mr. Gilmore’s absence in Alaska 
and the time subsequently consumed in the writing of his report. 
Aside from the above, Mr. Gilmore has devoted his attention mainly 
to the preparation of Camptosaurian material, which has progressed 
as rapidly as could be expected, and he feels confident of beimg able 
to mount one and perhaps two fairly complete exhibition specimens. 
The working out of the very large collection of Stegosaurian material 
has also been begun.’ Some 2,500 catalogue cards were prepared. 
Mr. J. W. Gidley has studied and described the Miocene and Plio- 
cene horses of North America, two new species of Pleistocene 
ruminants, a new species of fossil deer from the Mascall formation 
of Oregon, a new species of multi-tuberculate mammal, a new species 
of Eocene mammal, a new species of Orbos, the position and mechan- 
ics of limb and foot structure of sundry small mammals, and a small 
collection of fossil mammals from the Miocene of Nevada. 
There are now cleaned and ready for mounting skeletons of a small- 
horned rodent, “pigaulus hatcher/, from Kansas; a creodont mam- 
mal, Sinopa, from the Bridger Basin of Wyoming; a shortlimbed 
rhinoceros, Teleoceras fossiger, from Kansas; two species of the 
Jurassic reptile, Camptosaurus; a fossil cetacean, Zeuglodon cetloides ; 
at least one 7itanotherium, and a Lower Eocene carnivore, /fop- 
lophonius. The type specimen of Ceratosaurus nasicornis can also 
be prepared for mounting in relief with a comparatively small 
amount of labor. In addition, it is expected that in another year or 
eighteen months the work of cleaning the bones of Stegosaurus unqu- 
latus, a reptilian form ranking in grotesque character with the 
Triceratops, will be completed. 
Paleobotany.—The principal accession in this division consisted 
of about 235 specimens of fossil plants, forming a part of the Gustav 
Hambach collection, previously referred to. It contaims 16 types 
from Florissant, Colorado, described by W. C. G. Kirchner in the
