Chondestes grammica, stigata, Buteo borealis socorroensis as new races, 

 and Tinnunculus sparverioides, Thrasaetus harpyia, and Actodromas 

 acuminatus as additions. (c) Genera described or added since 1S59, ant ^ 

 generic names orthographically emended since that date. Under this 

 heading are briefly discussed the status and history of three "genera" 

 among the Thrushes, including a defence of Mcrula as a generic designa- 

 tion for our common Robin, and the genera Myiodioctes, Ulula, etc. (</) 

 Species included which are not yet known to have been taken within the 

 prescribed limits, (e) Old World species of regular occurrence in Green- 

 land or merely casual visitants to Eastern North America. (_/~) " Palse- 

 arctic" and oceanic species occurring in Alaska or on other parts of the 

 Pacific coast. (g) " Palsearctic" species found in both Greenland and 

 Alaska but not at intermediate points, (h) Tropical American species 

 occurring only in the southern portions of the United States. (/') Sup- 

 posed valid species described by Audubon and Wilson, but not since met 

 with, and of which there are no known specimens extant. (/) Untena- 

 ble species and races described since 1S5S. (X-) Exotic species apparently 

 wrongly attributed to North America. (/) Partial list of foreign birds 

 which have been introduced, or which have been captured after escape 

 from confinement. Each of these lists is appropriately annotated, the an- 

 notations varying in character with the special requirements of the several 

 categories, and the information thus succinctly presented is not only of the 

 most useful and interesting kind, but hard to find when wanted without this 

 admirable index of references. 



The " Addenda" gives, first, a commentary on 6 species, 4 of which are 

 supplementary to those contained in the Catalogue itself. Then follows a 

 list of the families of North American birds, with the number of genera 

 and species of each recorded in the Catalogue, and finally a " Concordance" 

 of the two Catalogues of 1859 and 1881, in which the corresponding 

 numbers of each are given in parallel columns.* There is also an "Index 

 to the Genera." 



As already noted, the present "Nomenclature" is a "revised edition" 

 of Mr. Ridgway's " Catalogue " of a few months' earlier date. But it 

 should be added that in a footnote to page 5 of the present work is given 

 a schedule of the more important changes from the first edition, which 

 embrace a new introduction, various changes of generic, specific, and 

 English names, and corrections of authorities. The work is exceedingly 

 free from typographical errors, and in every way evinces the exercise of 

 the utmost care in its preparation. — J. A. A. 



Ridgway's Revised Catalogue of the Birds of Illinois, t — The 

 present catalogue is based primarily upon the same author's "Catalogue 



* The numbers of the old catalogue are also given in the new, following the English 

 names and enclosed in brackets.
