Sp. Chau. (8.454 Shoalwater Bay, W. T., March 10, 1854; Dr. J. G. Cooper.) Above 

 phinibeous-unjher, inclining to gruyitth-phnubeous on wings an<l tail; shafts of the dorsal 

 feathers conspicuously while. Whole crown and nape, aliove the lores and auriculars, 

 sooty-black ; separated from the brown of the back by a whitish tint. Forehead (narrow- 

 ly), nasal tufts, lores, whole lateral and under side of liead. with jnguluni. pure white, rest 

 of lower parts a duller and more brownish white. Wing, .5.50; tail, 5.30; culmen, .93; 

 tarsus. 1.20. Young (5,904, Shoalwater Bay). Entirely plumbeous-brown, inclining to 

 brownish-whitt* beneath. Dorsal feathers with white shafts, and those of the forehead, 

 crown, and nape, as well as the wing-coverts, with obsolete whitish borders. 



This form, as described above, seems to lie peculiar to the northwest coast, 

 reaching its extreme develo2)ment in Washington Territory and Oregon. 

 Xorth of Sitka, and in the Yukon Territor}-, specimens incline toward the 

 var. canadensis, in broader frontal w^hite, and ])urer jdumbeous colors. 



Habits. Dr. Cooper met with this variety at the mouth of the Columbia 

 Eiver in March in small scattered flocks, industriously seeking insects and 

 seeds among the spruce-trees, occasionally whistling in a loud melodious 

 tone like that of the Cardinal Crrosbeak. He also states that the notes of this 

 bird (lifter much from the other Jays in being clear and musical, and they 

 sometimes show a considerable variety of song. 



This Jay, Mr. Lord states, is so familiar and confiding, and so fond of 

 beinjj near the hal)itations of man, that the settlers never harm it. In the 

 cold weather he has seen it hop by the fire, ruffle up its feathers and 

 warm itself without the least fear, keeping a sharp lookout for crumbs, and 

 looking so beseechingly with its glittering gray eyes, that no one could 

 refuse such an appeal for a stray morsel. It winters in British Columbia 

 and Vancouver Island.

 light bluish-plumbeous, becoming much lighter on the anterior portion of the back ; 

 tertials, secondaries, w'ing-coverts, primaries, and tail-feathers passing into whitish 

 terminally, on the latter forming quite broad and distinct tips. A nuchal patch of a 

 slightly darker tint than the back, and separated from it by the hoary whitish of the 

 anterior dorsal region. Whole of the head (except the nuchal patch), with the anterior 

 lower parts, as far as the breast, puri' white; rest of lower parts ashy-white, becoming
