 ample, as follows : — 



Merula migratoria. Dolichonyx oryzivorus. 



Turdus u. swainsoni. Charadrius dominicus. 



Turdus a. pallasi. Actitis macularia. 



Turdus fuscescens. Tryngites subruficoUis. 



Galeoscoptes carolinensis. Larus Philadelphia. 



Harporhynchus rufus. Rhodostethia rosea. 



Dendroica virens. Xema sabinii. 

 Anthus pensilvanicus. 



Tlie migration of each of the nearly four hundred species is treated in 

 detail, sometimes several pages being given to a single species. A work on

 Cory's 'Birds of the Bahama Islands', issued a few months since, is a 're-

 as given in the first edition, and the last named species is considered as 

 identical with 5. ricordii. The 'changes in nomenclature' consist mainly 

 of a concordance, showing the present equivalents of various names used
