INTRODUCTION. 
National Museum at Eio de Janeiro, made "with the kind help 
of Professor Orville A. Derby, has also yielded some new facts; 
while a study of the small series of Swiss Neocomian fishes and 
Lebanon Cretaceous fishes at Geneva, thanks to the kindness of 
Drs. Bedot and Weber, has elucidated several points left doubtful 
by PictePs original descriptions. The Museums of the Universities 
of Munich and Naples have been re-visited ; while the Woodwardian 
Museum at Cambridge, and the Willett Collection in the Brighton 
Museum, have proved as useful to the author now as in the prepara¬ 
tion of the previous volumes of the Catalogue. Thanks are not only 
due to the many friends and colleagues in Palaeontology who have 
facilitated these researches, but also to Mr. G. A. Boulenger, P.B.S., 
whose valuable advice and assistance have been continually at 
the writer’s disposal, and whose opinions concerning the general 
relationships of the higher fishes ^ correspond very closely with those 
suggested by this Catalogue.
