APPENDIX. 



In the preparation of this Appendix it was found necessary to 

 examine somewhat exhaustiyely the literature relative to that part of 

 Ord's Zoology included in his tabulated lists. In this labor I have 

 been exceptionally favored by free access to the unexcelled scientific 

 library of the Academy of Natural Sciences of Philadelphia. The 

 results of this study, especially with respect to the Mammals, seem 

 to show that the nomenclature of Mammalogy yet affords a wide 

 field for critical investigation, ere we shall be able to give due credit 

 to the work of pioneers in this branch of natural history. 



The labors of American Ornithologists during the past twenty years have 

 left comparatively little to be done in our scientific ornithology. The 

 appended notes on Ord's catalogue of Birds were mainly compiled by 

 my friend, Mr. Witmer Stone, of the Academy of Natural Sciences. 

 To Dr. Elliott Coues I am much indebted for his critical inspection 

 of the manuscript of this Appendix and for valuable suggestions 

 regarding the bibliographic and historical questions involved. I am 

 also indebted to Prof. E. D. Cope for a similar service in respect to 

 the table of "Amphibia." The names of those species to which Ord 

 gave new binomial names are printed in heavy faced type. A 

 summary of the changes in nomenclature proposed may be found at 

 the end of this Appendix. 



TITLE PAGE. 



As noticed in the Introduction, the Title Page of the only copy of the 

 Second American Edition of Guthrie's Geography seen by Dr. Coues 

 was defective, (Birds of the Colorado Valley, 1878, Bibliographical 

 Appendix, P. 603.). The titles of the first and third American editions 

 of Johnson and Warner (afterwards Benjamin Warner) are as follows: 



The title page of the first (1809) edition is identical in word and 

 spacing with the second edition to and including the words "To which 

 are added:" under the table of contents; from this it reads 

 || A geographical index with the names of places alphabetically ar- || 

 ranged. 2. A table of the coins of all nations. 3. A chro- || nological 

 table of remarkable events, from the || creation to the present time. || 

 By William Guthrie, Esq. || The astronomical part by James Ferguson, 

 F. R. S. 'I To which have been added, || the late discoveries of Dr.
