PREFACE. Tii 



Among tlie Officials at tte British Museum, I must record my acknowledgments to 

 Professor Owen, c.b., Mr. Winter Jones, and the late Br. J. E. Gray, for such help as they were able 

 to affiard me to obtain free access to the Ichthyological collection. 



At the Hague, the late Dr. Bleeher, not only permitted me free access to his invaluable 

 Ichthyological Museum (containing about 2000 species),* his notes and his unpublished figures of 

 fish, but he also assisted me with his opinion on the validity of species as well as presented me 

 with many of his types. In him I have personally to deplore the loss of a kind friend, and one 

 who stood unrivalled among the Ichthyologists of the present time. 



Professor Schlegel, the Director of the Leyden Museum, and his able Ichthyological assistant. 

 Dr. Hubrecht, have rendered me invaluable assistance. The latter, as may be seen in the pages 

 of this work, has been indefatigable in searching out superior examples of such fish as I desired 

 to figure, but of which I did not possess sufficiently good specimens. 



At Paris, I have to offer my thanks both to M. VaUlant and Dr. Sauvage, who most kindly 

 assisted me at the Museum in the Jardin des Plantes, more especially in respect to the type 

 specimens of Cuvier and Valenciennes^ great work on Fishes. I cannot resist noticing here how 

 excellently preserved and scientifically registered the fish in that unrivalled Ichthyological 

 Collection are. 



I have also to give my best thanks to A. 0. Brisiane Neill, Esq., of the Madras Medical 

 Service (retired), for his valuable assistance in carrying this work through the press, a labour 

 which can scarcely be appreciated except by those who have undertaken similarly arduous tasks.
