X PREFACE. 



Norfolk, naturally suggested itself as of chief interest, 

 and I consider myself most fortunate in once more 

 securing Mr. Wolf's services, whose original drawing 

 for the present frontispiece was made from sketches 

 of living specimens, in the Regent's Park Zoological 

 Gardens. The drawing on the stone and colour pattern 

 were executed by Mr. J. Smit, and the plates have 

 been coloured by hand by Mr. William Smith, with 

 his usual ca.re a,nd skill.
