„ Junco annectens, (Baird.) — An adult specimen, probably a 
female, since it is smaller than the males in the National Museum 
and other collections, differs from typical examples in having the 
pinkish of the sides invading the whole breast and strongly ting- 
ing the throat. In other respects, however, it does differ from 
ordinary specimens. Its measurements are as follows : Wing, 
3.20; tail, 2.80; bill, from nostril, .35; tarsus, .78.
