Sab. — The typical form from the Northern Pacific slopes, from Sitka southward. 

 Shading, in the Cascade, Coast Rauge, and Sierra Nevada of California, into var.

 (and eastward to Fort Lyons, in the Arkansas Valley). Inosculating with stelleri 

 proper about the head-waters of the Columbia ; separated from it thence Southward by 

 the Great Basin. Passing, on. tbe Table-lands of Mexico, into var. diadematus, and 

 this last passing southward into v.ar. coronatus.
