the species is stated and the particular locality from which the 

 specimen exhibited was obtained. In addition information is 

 given as to any matters of special interest concerning the 

 fish. This Guide is a collection of the labels with some 

 additions, arranged systematically so as to shew the groups 

 into which fishes are divided, and is illustrated by figures 

 which are to a large extent taken from photographs of the 

 specimens actually seen in the cases.

ADDENDUM. 



Since the above preface was written, it has been thought desirable 

 not to use the " thick large type " for the numerals denoting the 

 individual specimens, and these have therefore been printed in 

 ordinary type.
