APPENDIX 



PLATALEiE (p. 1) and HERODIONES (p. 56). 



Owing to various causes the preparation of the present volume has 

 been delayed, and consequently many additions to the foregoing 

 pages have become necessary. It has therefore been considered 

 more convenient to place the " Appendix " at the immediate end 

 of the descriptions of the species of Herons, in order that the 

 additions can be more easily studied.
