288 Mr. G. K. II. Burrett-lJamiltuu on 



and coloured drawing can give any true idea of the lavish 

 mixture of various colours exhibited in summer by the bill of 

 Lunda cirrhata ; but I do not here repeat a description of the 

 soft parts of this particular species, although I made a sketch 

 of the bilb because they have already been given in detail 

 by Dr. Stejneger. Realizing therefore the impossibility of 

 attaining to exactness, I have thought it well not to amend 

 the nomenclature of my original rough notes as regards the 

 colours of the soft parts of the specimens, since after all the 

 effect of the most elaborate scheme invented for the purpose 

 cannot convey to the imagination one half the glories of some 

 of these as seen in their original freshness. It must be 

 borne in mind, however, that in many cases the colour of the 

 same part varies in different individuals of the same species, 

 even when obtained on the same date, so that when I have 

 used different names for the same part of different individuals 

 of the same species, I may often be quite correct in doing so.
