lower parts are of a yellowish rather than silvery white, the crissum 

 aud flanks are more decidedly tinged with buff", the lores are distinctly 

 dusky, and the upper parts are decidedly more tawny. Two of the five 

 specimens have the maxilla a clear light-brown color, ichich I have never 

 seen in an American specimen. The measurements are as follows :

Two examples from England differ from all continental specimens 

 which I have seen very nearly as much as C. mexlcana does from the 

 ordinary North American bird ; and since it would appear from descrip- 

 tions that these specimens represent the normal style of coloration of 

 specimens from the Bi'itish Islands, I see no alteruative but to charac- 

 terize the British specimens as a race always distinguishable from the 

 two continental forms. These British examples are very much browner 

 above than those from the continent (closely resembliug, in this respect, 

 Californian specimens hereinafter described as occidenfaUs), the rump is 

 more deeply tawny, aud the lower parts appear to be of a much duller 

 white, though this may be owing to a soiling of the plumage. These 

 are the specimens which in History of North American Birds (i, pp. 124, 

 125) were supposed to be the true C. familiar is, thus leading to the erro- 

 neous views of their relationships therein given. TLie measurements 

 are as follows, the tail being in both examiiles much worn at the tip, and 

 therefore not included :

Creepers from eastern North America have almost invariably a de- 

 cidedly shorter bill and hind claw than European specimens, while
