R. Ridgway, Proc. Un. St. Nat. Mus. Vol. 5. p. 113. 



Very much browner above than exaniples from the continent 

 (closely resembling-, in this respect, Californian specimens herein- 

 after described as occidentolis) , the rump is more deeply tawny, 

 and the lower parts appear to be of a much duller "white though 

 this may be owing to a soiling of the plumage. 



Hab.: England. 

 +- 386. Certhia montana. 



R. Ridgway, Proc. Un. St. Nat. Mus. Vol. 5. p. 114. 



The general tone of coloration is decidedly grayer above than 

 in any other form of the species, the flanks are decidedly grayish, 

 the crissum more pronounced buff than in either of the three 

 European races, and the tawny of the rump in more abrupt con- 

 trast with the grayish of the back. The most decided difierences, 

 however, are in proportions: thus, while the wing averages shorter 

 than in either famüiaris or Costae, the tail is decidedly longer ; 

 the bin also averages much louger than in famüiaris or Costae, 

 but is altogether more slender, both the vertical height and the 

 transverse thickness being much less. As is the case with all the 

 American races, the hallux and hind claw — the latter especially — 

 are almost constantly shorter than in the European forms. 



Hab.: Middle Province of North America; (north to Kadiak, 

 Alaska) breeding south to New Mexico and Arizona, in wooded 

 mountains. 



-^287. Certhia occidentalis. 



R. Ridgway, Proc. Un. St. Nat. Mus. Vol. 5. p. 115. 



Next to mexicana, this is the darkest colored of all the races 

 of this species. In extremely slender bill it agrees with montana 

 but, apparently, has a shorter tail (although this apparent difference 

 may be due to an insufficient number of specimens compared-one 

 specimen having the tail 15 of an inch longer than the longest- 

 tailed specimen of montana), but the colors are strikingly dififerent. 

 Instead of being grayer than rufa, occidentalis is much browner, 

 extreme examples having the light patches of the remiges a bright
