c. Sides and flanks light brown; outermost tail feathers not more than one- 

 half white; general coloration much darker and form much stouter. 



Junco fulvescens, young. 

 ee. Sides and flanks buff; outermost tail feathers mostly white; general col- 

 oration much paler and form much more slender.. Junco bairdi, young. 



The following have not been included in the preceding ''ke}^" on 

 account of their unsatisfactoiy status. They each represent a con- 

 necting series between two well-characterized forms, and in my opinion 

 are .simply hybrids and not true *" intergrades."

Junco annectens Baird, in Cooper's Orn. Cal., 1870, 564 (type from Fort Bridger, 

 Wyoming, in IT. S. Nat. Mus.-). — Ridgway, Nom. N. Am. Birds, 1881, no. 



' This type specimen, which I have carefully examined and compared, is No. 7046 of 

 Mr. Brewster' s collection, and was taken by Mr. Brewster at Colorado Sjirings April 26, 

 1882. It is very nearly typical of ,/. Jiyeinalis, with sides only slightly tinged with cinna- 

 momeous and the back slightly brownish. It may be a young female, of the preced- 

 ing year, of J. hyemalis; at any rate it has nothing to do with tlie form of /. oreganus 

 {J. 0. shufeldti) , to which the name connectens was unadvisedly applied by action of the 

 A. O. U. Committee in 1896. 



-Although of the several specimens considered l>y Professor Baird to represent his 

 /. annectens all but one represent J. mearnsi, it is nevertheless easy, in view of the 

 characters most prominently mentioned in the diagnosis, to determine which should 

 be considered as the type. For instance, the phrase " wliole interscapular region . . . 

 light chestnut rufous," found in the description, applies only to no. 11164, an adult 

 male from Fort Bridger, obtained April 12, 1858, all the other specimens then in the 

 Smithsonian collection having the interscapular region hair brown, very different 

 indeed from chestnut-rufous. The remarks which follow the description are, so far 

 as they apply to the color of the back, equally convincing, for it is distinctly stated 

 that the color is "that of caniceps, not of oregonus," the back of./, mearnsi being even 

 less rufescent than that of J. oreganus.
