80 REVIEW OF AMERICAN BIRDS. [PART I. 
Thus far I have seen none of the common Black-capped Titmouse 
(2. 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. N. 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 Parus meridionalis, than the North 
American Black-caps.
