564 ADDITIONAL SPECIES. 



This species is almost exactly like D. iiiijresceiis in the color and murliings of 

 the back (with its blackish interscapular streaks), 'wings, and tail, as well as of the 

 under parts, except that the chin and throat are yellow, margined with black, 

 instead of black margined with white. The heads are, however, very difierently 

 marked. 



This interesting addition to the fauna of Arizona was made by Dr. Coues, during 

 his residence in that Territory. It is an inhabitant of the pines about Prescott, 

 where it breeds, though its nest was not obtained. It has much the habits of 

 other warblers, without any very striking or conspicuous note. 



Junco annectens, Baird. 



THE FINK-SIDED SNOW-BIRD. 



Sp. Char. TMiole upper jiarts, with head and neck all round, and upper part of breast, 

 nearly uniform ah^h-color ; this on the under surface with a convex outline behind, and 

 not extending under the wings. Whole interscapular region, outer webs of greater wing 

 coverts, and sides of body from bend of wing, liglit diestnut rufous ; paler beneath, and of 

 a pinkish tinge, and contrasting quite abrui)tly with tlie white of middle of breast, belly, 

 and anal region. Lores abruptly darker; outer two tail leathers white, the next with 

 longitudinal white stripe Bill yellow, with dusky tip; legs yellow. Length, 5 50; wing, 

 3.10; tail, 2.80. 



Hab. Rocky Mountains to Arizona. (Fort Bridger, Fort Burgwyn, and Fort Wliip- 

 pie.) 



This species or race is so decidedly intermediate in character between J. Ore- 

 gonus and caniceps, that I have always considered it (with concurrence of Dr. 

 Coues, who met with it in life) as a hybrid between the two. The characters, 

 however, appear very constant, the relative share of the two species being always 

 preserved, and I think, therefore, that iF'is entitled to a provisional appellation, 

 even if a hybrid. In the case of the Upper Missouri hybrid Colaptes (between 

 Mexicamis and auratus), no two specimens are alike in the proportional share of 

 features of the parent species, while in the present instance there is a decided 

 constancy. 



The general appearance is that of canicejis, in the light, uniform ash-eulor of 

 the upper and anterior jjortion of body, and the blackish lores in appreciable con- 

 trast with the rest of the face. The posterior outline of the ash on the breast, 

 however, is not concave, extending along the sides as in caniceps and hi/emalis, but 

 convex, transverse, and on tlic sides washed with pinkish-rufous, as in Ore</oiiiis. 

 This latter color, however, is usually deeper, more extended, and better defined 

 against the white of the belly. The chestnut or rufous of the back is not con- 

 fined to the interscapidar region, as in canicep.^ but extends on the wing coverts as 

 in Oregonus and ciiiereus. Its color is, however, that of cauiaps, not of Oregoiitis.
