of the Sierras, numbers occupying the same reach of stream when food is abundant.

9. Sialia arctica, Sw.—Rocky Mountain Bluebird. 
Apparently much rarer than the preceding species ; indeed, I am not positive that I 
detected its presence at all, though a flock of Bluebirds seen in the high Sierras late 
in October were supposed to be of this species. This seems the more probable, as Dr. 
Cooper speaks of finding it numerous about Lake Tahoe and the summits of the Sier¬ 
ras in September.

10. Begulus calendula , (L.)—Ruby-crowned Kinglet. 
This species is very abundant during the migrations, and may perhaps be yet found 
breeding in the high mountains of Southern California, as it probably does in the more 
northern half of the State.

11. Polioptila ccerulea, (L.) —Blue-gray Gnatcatcher. 
The neighborhood of Fort Tejon was the only locality where this Gnatcatcher was 
seen. It was here particularly numerous, the bushes along the sides of the canons be¬ 
ing for some reason or other especially favored by their numbers. Neither here nor 
elsewhere was the closely-allied species P. melanura detected.

The Ground Wren appears to inhabit Southern California at large, and was detected 
by us at several widely-separated points both in the Coast range and the Sierras. Its
