134 Mr. D. G. Elliot on HOrbigny’s Specimens of 
mentioned by him are not represented among his specimens 
in the Museum; and in certain instances, where he has re¬ 
ferred them to a well-determined species represented by 
Lesson in one or other of his works on this family, I have 
retained them under the modern name of such species; but 
in cases where the indications are either imperfect or do not 
exist at all, it seems to me that it will be necessary to exclude 
D^Orbigny’s names from the nomenclature of the group, as, 
access to his specimens failing, there remains no possible 
way of ascertaining what were the species he intended to 
describe. 
I desire to express my thanks to Prof. A. Milne-Edwards 
and to Mons. E. Oustalet, Aide-Naturaliste, for the great 
facilities afforded me in examining the specimens and records 
relating to them in the Museum under their charge. 
The species, in the following remarks, are arranged in the 
order in which they stand in the ( Synopsis Avium/
