These species are all new and, with the exception of the American 

 eland, the dog, and one of the bears, which Air. Gidley has already 

 described,^ have not yet been named. 



( )ther species represented by more fragmentary material inclnde 

 the mastodon, tapir, horse, and beaver, besides several species of the 

 smaller rodents, shrews, bats, and others. 



Idiis strange assemblage of fossil remains occnrs hopelessly inter- 

 mingled and comparatively thickly scattered through a more or less 

 unevenly hardened mass of cave cla\s and breccias, which com- 

 ])letelv filled one or more small chambers of a limestone cave, the 

 material together with the bones evidently having come to their final 

 resting place through an ancient opening at the surface a hundred 

 feet or more al)Ove their present location. The deposit is at present 

 exposed at the l)ottom of a deep cut through which the A\'estera 

 Maryland Railroad has built its tracks. The railroad excavation first 

 brought to light the ancient bon.c deposit and incidentally made access 

 to the fossils comparatively easy. It is proposed to continue work 

 on this important deposit during the next season. 



A FOSSIL HUNTING EXPEDITION IN MONTANA 



\\ bile engaged in Geological Survey work in northwestern Mon- 

 tana in 1912, Air. Eugene Stebinger discovered a promising locality 

 of vertel)rate fossil remains. The following summer (T913), imder 

 the auspices of the U. S. Geological Survey, Mr. Charles W. (iilmore, 

 assistant curator of fossil reptiles in the National Museum, headed 

 an expedition for the purpose of obtaining, if possible, a representa- 

 tive collection from this area. 



In |ul\' a camp was established on Milk River, some thirtv-five 

 miles north and west of Cut Ijank, iMontana, on the Blackfeet Indian 

 Reservation. Foin* weeks were spent here in collecting, the work 

 being confined entirely to the Upper Cretaceous (Belly River beds) 

 as ex])ose(l in the bad-lands for ten miles along this stream. Later. 

 in August, camp was moved some fifty miles south on the Two Medi- 

 cine River, and two weeks were spent working in the same geological 

 formation. 



Taking into consideration the short time at the disposal of the 

 party, the results of the expedition were most gratifying. Between
