54 REPORT OF NATIONAL MUSEUM, 1908. 



Giistav PTambach collection included a number of fossil fishes, rep- 

 tiles, and mammals. The collection oljtained by Mr. C. W. Gilmore 

 on the Smithsonian expedition to Alaska during; the summer of 

 1907 and deposited in the jNIuseum contains several fragmentary 

 specimens representing fossil species of the mastodon, bison, musk ox, 

 caribou, beaver, etc. The most important find was a nearly complete 

 skull of a new species of Ovibos, which Mr. Gidley has described 

 under the name Ovihos yul'onensis. A fossil turtle from the Kansas 

 chalk is also worthy of mention. 



The Teleoceras remains, so extensively represented in the Marsh 

 collectio-n, 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, Avhich has progressed 

 as rapidly as covdd be expected, and he feels confident of being 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 Ovibos^ 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, Epigavliis luifchen, from Kansas; a creodont mam- 

 mal, SinojM^ from the Bridger Basin of Wyoming; a shortl imbed 

 rhinoceros, Teleoceras fossiger, from Kansas; two species of the 

 Jurassic reptile, Camptosaiirus/ a fossil cetacean, Zeiiglodon cetoidcs; 

 at least one Titanotherium,, and a Lower Eocene carnivore, Hop- 

 lophonius. The type sjDecimen of Geratosaumis 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 ungu- 

 latus, a reptilian form ranking in grotesque character with the 

 Trireratops. will be completed. 



Paleohotany. — 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 contains 16 types 

 from Florissant, Colorado, described by W. C. G. Kirchner in the
