"The present volume contains several genera of Fishes so 

 extremely rich in species, that we must not expect to find the 

 greater portion of them united in one collection. However, in order 

 to give as many original descriptions as possible, and to determine 

 with accuracy the specimens in the British Museum, several of the 

 Continental Museums have been personally examined. Prof. Schlegel 

 of Leyden, Dr. E. Ruppell of Frankfort, Prince Max of Neuwied, 

 Prof. Peters of Berlin, Prof. Troschel of Bonn, Dr. v. Bleeker of 

 Batavia. Prof. Aitkcn at Fort Pitt, Prof. Gill of Washington, <fec., 

 &.C., have either given mo much valuable information, or most 

 liberally assisted me during my visits to their collections."
