ORNITHOLOGY. — Critical notes on the eastern subspecies of Sitta 

 carolinensis Latham. Harry C. Oberholser. The Auk 24: 

 181-187. April, 1917. 

 Although the white-breasted nuthatch of the eastern United States 

 has been recently divided into three forms, careful investigation now 

 shows that only two, a northern and southern, are recognizable. The 

 race from Florida, hitherto called Sitta carolinensis atkinsi, must now 

 be known as Sitta carolinensis carolinensis Linnaeus, since birds from 

 the type locality of the latter, South Carolina, are referable to the 

 Florida form. The recently described Sitta atkinsi litorea of Maynard, 

 from the coast region of southern North Carolina, consequently becomes 

 a synonym. True Sitta carolinensis carolinensis therefore ranges from 

 Florida and Louisiana north to southern North Carolina and southern 

 Illinois. The bird of the northeastern United States, from northern 

 Illinois and northern North Carolina northward into southern Canada, 

 heretofore called Sitta carolinensis carolinensis, becomes therefore 

 nameless and is here christened Sitta carolinensis cookei. H. C. 0. 



ORNITHOLOGY. — A synopsis of the races of Bombycilla garrula 



(Linnaeus). Harry C. Oberholser. The Auk 24: 330-333. 



July, 1917. 



The Bohemian waxwing, which occurs in northern North America, 



northern Asia, and northern Europe, although heretofore supposed to 



be undifferentiated into geographic races, is found to be made up of 



three recognizable subspecies. These are Bombycilla garrula garrula 



(Linnaeus), from Europe; Bombycilla garrula centralasiae Poljakov, from 



central and northern Asia; and Bombycilla garrula pallidiceps Reichenow, 



from North America. The North American representative proves to 



be a well-marked form. H. C. 0.
