REVIEW OF AMERICAN BIRDS. 



[part I. 



Thus far I have seen none of the common Black-capped Titmouse 

 (P. atricapillus), from the line of the Missouri River and westward 

 to the Rocky Mountains, that were not referable to the long tailed 

 species. Specimens vary in amount of white on the wings and tail, 

 but the real characters are pretty constant. The specimens at 

 present in the collection, however, are not in sufficiently good con- 

 dition, nor numerous enough, to exhibit the exact limitations of the 

 two species. 



I^have already referred (B. X. A. 389) to specimens from the 

 southern Rocky Mountains (Fort Massachusetts), in which the 

 white markings are of a plumbeous tinge. Some others, since re- 

 ceived, exhibit this same character, and it is not impossible that it 

 may indicate a specific form. The specimens, however, are not in 

 sufficiently good condition to settle the question, but their general 

 appearance is more that of Farus meridionalis, than the North 

 American Black-caps.
