III. Progress of Correlation Work. 
Dr. Louis Dollo’s valuable detailed report upon the succession of verte¬ 
brates in the Mesozoic and Cenozoic horizons of Belgium is accompanied by 
a full description as to location of types, etc. This report has been trans¬ 
lated by Dr. Matthew and is to appear as Bulletin No. 2. 
Dr. Osborn has continued his researches on the correlation of the Ceno¬ 
zoic, especially of France and of North America, in cooperation with Pro¬ 
fessor Charles Deperet in France and Dr. W. D. Matthew in North America. 
A preliminary report on this correlation is now in course of publication by 
the United States Geological Survey. 
Dr. W. D. Matthew has completed a full series of faunal lists of the 
Tertiary Mammalia of North America which also are ready for publication. 
The lists of other vertebrates, that is, Reptilia, Aves and Amphibia, are 
completed down to the year 1900 with the data, so far as readily obtainable.
