1922] Swarth: Birds and Mammals of the Stikine Region 249 



as previously shown, the juneo of the Stikine region, although in a 

 sense intermediate in appearance between hyemaUs and oregamis, can 

 not properly be considered as an aggregation of hybrid individuals. 

 The only alternative left, therefore, is to consider this form as a dis- 

 tinguishable geographical race of the species it most nearly resembles, 

 and apply a separate name, as I have done. 



As we descended the Stikine, leaving the habitat of connedens 

 behind and drawing nearer to that of oreganus, every effort was made 

 to secure juncos. At Telegraph Creek and Glenora, juneos {connec- 

 iens) were abundant. At Doch-da-on Creek, though in lessened num- 

 bers they were still fairly numerous, and all still of the same subspecies. 

 Our next stop was at Flood Glacier, some forty miles down stream 

 and about seventy miles from the coast. There we were in a region 

 where either coast or inland species might occur, and the junco was 

 one of several birds that we searched for especially at that point. 

 Juneos were not numerous, however, and our two weeks of collecting 

 there yielded but fifteen specimens. Of these, eight are adults, six 

 males and two females. The two females are Junco o. oreganus, beyond 

 a doubt. Of the male birds, one (no. 39999) is typical connedens. 

 It is in extremely worn plumage but is evidently of exactly the same 

 character as Telegraph Creek specimens. One bird (no. 39993), while 

 not an average connedens (it shows some rusty on the back), can be 

 matched by one variant taken at Telegraph Creek. Another (no. 

 39998) is somewhat more reddish on the. back, though the sides are 

 slaty. The remaining three adult males (nos. 39987, 39988, 39990), 

 if taken farther south, in their winter home, would undoubtedly be 

 considered as examples of Junco oreganus shufeldti. They are shorter 

 winged than Arizona winter specimens of shufeldti, but they have 

 the black head (a glossier black above than in connedens), brownish 

 back, and pink sides of that race. However, despite their general 

 appearance, I cannot believe that these birds are shufeldti. I do not 

 believe it possible for the habitat of that subspecies to extend north- 

 ward as a tongue inserted between the ranges of connedens and 

 oreganus. Juncos can not be distributed uninterruptedly from the 

 southward over the glacier covered mountains that constitute so large 

 a part of this intermediate region. Their distribution must lie in nar- 

 row ribbons along the river valleys extending from the interior to the 

 coast, such as the Stikine, and the affinities of birds taken at any one 

 point in these valleys must lie with others immediately adjacent, above 

 and below. Therefore, despite the superficial resemblance of these
