SITTA.

? Sitta carolinensis, ScuatER, P. Z. S. 1856, 293 (Cordova) ; 1858, 300 
(Oaxaca) ; 1859, 363 (Xalapa), 373 (Oaxaca). 
Hab. Western and Middle United States, south to Cordova, Mex. 
As remarked in Birds N. Am., the only appreciable difference 
between this species and the preceding is in the much slenderer bill. 
The Mexican White-bellied Nuthatches seem to belong here rather 
than to the carolinensis ; at least the specimens I have seen do so. 
It is very difficult to express this difference appreciably ; but a com- 
parison of large series from the two localities will readily illustrate 
the fact as will the figures cited in B. N. A. 
Mr. Sclater calls attention to the inferiority of size of his speci- 
mens from Oaxaca; this might be anticipated from their southern 
locality as resident birds.
