APPENDIX. 
The best known Monograph of the Paradiseidce hitherto published is that by Mr. D. G. Elliot. 
This Monograph was written in 1873: it is illustrated by magnificent plates, lithographed by Smit from 
original drawings by Joseph Wolf. Gould, in his * Birds of New Guinea,’ figured nearly every species 
known in bis day, and he bad intended to publish a complete Monograph of the Family, for which 
purpose he kept the lithographic stones from which the plates in his above-mentioned work had been 
prepared. Thus it came to pass that when Messrs. Sotheran purchased the stock of Gould’s works after his 
death, they acquired the stones with which he had intended to illustrate his Monograph of the Paradiseidce. 
Many of them were broken or otherwise damaged, and of these some have been redrawn or replaced by 
new plates by Mr. Hart. Since Gould’s time, however, many marvellous new species have been discovered, 
and these have been described and figured in the present work. 
The most elaborate memoir of the Birds of Paradise, however, is that published by Count Salvadori in 
his ‘ Ornitologia della Papuasia e delle Molucche.’ With the exception of the Australian species, which 
did not come within the scope of Count Salvadori’s work, every Bird of Paradise and Bower-Bird is treated 
of in a way that practically exhausted the subject at the time; and I may once more take the opportunity of 
acknowledging the obligation I owe to the labours of my friend Count Salvadori, as from bis work the 
synonymy of most of the species in the present Monograph is taken. 
In 1894 I published a list of the Paradiseidce and Pt'ilon orhyn chi da; (Bull. Brit. Orn. Club, iv. pp. xii-xv). 
It is not so complete as it ought to have been, as I omitted Pferidophora alberti and Crcispedophora ctlberti, 
and the number of species should have been 84 instead of 82. 
Dr. A. B. Meyer, who has always occupied himself with the study of the Paradiseidce, and has described 
some of the most wonderful forms, such as Pferidophora alberti , Astrar chia Stephanies, Paradisornis rudolphi, See., 
has recently published a complete list of the known species (Abhandl. k. zool. Mus. Dresden, vii. 
no. 2, pp. 39—63). This is an invaluable contribution to our knowledge of the Birds of Paradise, of which 
96 species are now recognized by Dr. Meyer. Lastly, in the ‘ Thierreich,’ the Hon. Walter Rothschild has 
monographed the Paradiseidce once more, and his essay is, therefore, the latest revision of the Family. As 
he has admitted in a recently published paper in his ‘ Novitates Zoological ’ (v. pp. 84-87), he differs 
considerably from me and from the other ornithologists above named in his estimate of the worth of certain 
genera and species. 
In place, therefore, of giving a complete historical list of the literature appertaining to the Paradiseidce 
and Ptilonorhynchidce, as was so well done by Mr. Elliot in his ‘ Monograph ’ that it would have to be 
copied here, I have decided merely to give a list of the species as recognized by me at the conclusion of 
the present ‘Monograph,’ with a few additional criticisms on the work of Dr. Meyer and the Hon. Walter 
Rothschild, so as to bring the book up to date.
