PREFACE. 



THE dry and mounted specimens of Reptiles and Fishes are 

 exhibited in two parallel Galleries on the west side of the ground 

 floor behind the Bird Gallery. The Batrachians are contained in 

 one large table-case placed in the cross gallery between the last 

 named and the Fish Gallery. 



This Guide gives a general account of the animals belonging to 

 these three classes. The first edition was written by Dr. Gunther, 

 late Keeper of the Zoological Department, and published in 1887. 

 The present (the fourth) edition has been revised by Mr. G. A. 

 Boulenger, the changes being mostly in the sections devoted to the 

 classes Reptilia and Batrachia. That of the Fishes,, except for 

 some corrections necessitated by alterations in the arrangement of 

 the specimens, has been left much as written by Dr. Gunther.
