printed in double columns, the representing species of each being 

 placed opposite to each other. 



The Linnsean orders are retained, while the greater divisions are 

 put into subclasses. Among the Linnsean Accipitres, the Raptor es 

 of the moderns, we find Aquila Washingtonii retained as a species. The 

 American osprey is separated from the European under the name of 

 Pandion Carolinensis ; but among European, North American, and 

 Australian specimens in our possession, we cannot discover charac- 

 ters on which we could found specific distinctions. Buteo Lagopus 

 and vulgaris are neither placed on the American side ; the first is 

 considered, and we think correctly, as the young of B. Sancti Johan- 

 nis, and to the other the name of B. Swainsonii has been applied. F. 

 peregrinus is represented by the species considered hitherto as such, 

 but now called the F. anatum : the habitat given is " the northern 

 parts." Astur palumbarius is represented by F. atricapillus. Circus 

 cyaneus is thought to be distinct from the American bird, which is 

 given as C. uliginosus, Noctua Tengmalmi of America is made di- 

 stinct, and is called JV". Richardsonii, while the Kite or Barn owl of 

 Wilson is named tit. pratincola. 



Among the Passeres of Bonap. and Linn., Insessores of moderns, we 

 find the following species, which have been considered identical, now 

 separated : Certhia familiaris, represented in America by C. Ameri- 

 cana ; Pica caudata by P. Hudsonica ; Corvus Corone by C. America- 

 nus; and the C. Coraw by C. Catototi; and Corvus Columbianus is 

 placed under the genus Nucifraga. Ectopistes migratoria is omitted 

 in the European side, but we believe it has been twice killed in Scot- 

 land, and would rank as an accidental straggler with as much pro- 

 priety as the Erythrophrys Americana. Among the remaining or- 

 ders there is less change, the species most closely allied showing at 

 once some specific distinction easily seized, at the same time the 

 comparative list is most interesting to look over, and still more so if 

 the two representing species can be at the same time compared. 

 Among the ducks, Clangula vulgaris is placed opposite to C. Ameri- 

 cana, the A. clangula of Wilson. Several of the above-named birds 

 we have examined, and at the time we thought very minutely, and 

 considered identical : a comparison of many specimens from each 

 country might induce a change of opinion ; and we have now to re- 

 gret that the distinctions between all those so closely allied had not 

 been shortly given, by which we should have been at once enabled 

 to judge of the propriety or impropriety of the Prince's separations.
