PREFACE TO THE REVISED EDITION. 



The original edition having been for a long time 

 exhausted, the publishers requested me to revise and 

 make such additions as were necessary to bring this 

 little volume up to date. In doing this I have 

 discovered that very little was necessary beyond a 

 more definite recognition of the differences which 

 subsist between the true Reptiles and the Batra- 

 chians, in accordance with the views of the most 

 celebrated zoologists of the day. I have permitted 

 the chapter on Gray's Banded Newt to remain, and 

 also the plate, although under the impression that 

 the species has been introduced into the British list 

 by error. The flattering reception which was ac- 

 corded to the first edition by the most competent 

 authorities in this country, encourages me to hope 

 that the present will share the good fortune of its 

 predecessor, and maintain its position in Popular 

 Natural History. 



April, 1893. M. C. Cooke.
