Type locality. — Northeastern North America. 



Geoij raphicol dhtrihution. — Eastern United States west to Indiana; 

 southern part of eastern Canada; in winter also to Texas. 



This species is apparently distinct from intermedins of Central 

 America, though in most respects quite similar.

This recent discovery of Mr. Nelson's is remarkably ditl'erent from 

 its nearest geographical relatives, l)eing, in fact, intermediate between 

 T. aedon aztecus and Troglodytes niuaculm striatulus. From the
