INTRODUCTION. 
In the summer of 1903, the Carnegie Museum became enriched through the gen- 
erosity of its founder with a magnificent collection of fossil remains, which, as 
regards the great group of Vertebrata, is without doubt the largest, most important, 
and most valuable assemblage ever brought together by a private individual in 
Europe, and rivals many of the more notable gatherings of fossil vertebrates in 
the public museums of the world. 
This splendid acquisition, long coveted by American and foreign institutions, 
was the famous Bayet Collection, amassed after years of patient effort and very 
great expenditure by Baron Ernst de Bayet of Brussels, who for a long time was 
the Secretary of the late King Leopold of Belgium. A brief summary of the con- 
tents of this wonderful collection, a mere coup d’wil, as it were, of the riches which 
it presented at first inspection, was contributed by Dr. W. J. Holland to Science 
for June 19, 1903, and its installation in the Carnegie Museum was duly recorded 
in the Annual Report of the same institution for that year.1 Some of the fossil 
avian remains in the collection were described in the second volume of the Memoirs 
of the Carnegie Museum, but with the completion of that paper systematic in- 
vestigation of the great wealth of material contained in the Bayet Collection was 
temporarily suspended. Recently, however, the present writer was invited to 
undertake the difficult and important task of classifying and arranging the fossil 
fishes contained therein, and the present article may be considered as preliminary 
to more detailed contributions based upon the collection which may be made in 
the future.
