EDITORIAL NOTE, 
Owine to unavoidable circumstances the original index issued with Volume XI 
of the Annals could neither be prepared nor revised in proof by the author of 
Volume XI or by the permanent editor of the Annals. As the index so issued 
contains many errors, and as in any case owing to the changes now made by the 
author in the supplement, even if accurate when issued it would no longer be so, 
the editor has compiled a single index to the species mentioned or described and 
plates contained in both Volume XI and its appendix. It is recommended that the 
index issued with Volume XI be replaced by the one now issued. Two copies of 
the revised and enlarged index are issued with the appendix to allow of a copy for 
Volume XI and for its appendix separately if desired.
