Di'Rixci the past sunimer coUectinji' in tlie Eocene deposits of Wvo- 

 mino- for the Department of Vertebrate Paheontol()()T was continued bv 

 Air. Walter Granirer. His party was four months in the field and 

 devoted its attention ])rinci])ally to the exposures of the Wind River 

 beds of the Lower Eocene formation in the Wind River basin in the 

 central part of the State. This is the formation in which the famous 

 skeleton of the small four-toed horse, Eohippus, was found in 1880 

 by Professor Cope's collectors. Fossil remains are rare in tiie Wind 

 River beds and usuallv are framuentarv and badlv preserved. Thev are 

 desirable, however, because they fill an important place in the Eocene 

 history of North America. The collection obtained this season com- 

 prises more than four hundred specimens, representing probably all of 

 the forms previously known to occur in the formation as well as several 

 new ones. It will, therefore, considerably increase our collection illus- 

 trating early Eocene life. 



AIr. Barxum Browx of the Department of Vertebrate Palaeontology 

 returned early in November from a field season spent in collecting in the 

 Laramie Cretaceous rocks of Montana. ]\Ir. Brown was assisted by 

 Mr. Peter C. Kaisen, and their efforts were richly rewarded by securing 

 the major portion of a ceratopsian skeleton besides parts of three skele- 

 tons of a new predentate dinosaur from the Hell Creek horizon. Further- 

 more, much material was obtained which will be used in mounting a 

 skeleton of the three-horned dinosaur Triceratops. 



There has been installed in the new accession cases of the Depart- 

 ment of Anthropology (Siberian Hall, southwest corner of the ground 

 floor) a selected series of specimens from the material collected by Mr. 

 Alanson Skinner last summer among the Winnebago, Ojibway and Cree 

 Indians, and by Mr. W. C. Orchard among the Penol)scot Indians. 



The twenty-seventh annual convention of the American Ornitholo- 

 gists Union is to be held at the Museum Tuesday to Thursday, Decem- 

 ber 7 to 9, inclusive.
