INTRODUCTION. 



Every " type-specimen ' is distinguished by a small disk of 

 green paper affixed to it ; and upon the label is a reference to 

 the work in which such " type- specimen "has been figured and 

 described. 



The student or visitor who desires intelligently to study the 

 Fossil Fishes in this Gallery will find it indispensable to com- 

 bine with it a careful examination of the fine collection of 

 living Fishes, prepared and mounted for exhibition in the first 

 North- Western Gallery of the Zoological Department, on the 

 other side of the Great Central Hall. 



It is only proper to state here that the Gallery has been 

 arranged by Mr. William Davies, F.G.S., with the assistance 

 of Mr. Arthur Smith Woodward, F.G.S., to whom the writer 

 is also much indebted for valuable assistance in the preparation 

 of this Guide.
